## Challenging Aspects
### Challenging Aspects in Above Code
1. **Resampling Strategies**: Implementing different resampling strategies (`multinomial`, `residual`, `stratified`) requires understanding each strategy's mathematical foundation. Each strategy affects how particles are selected based on weights differently.
– **Multinomial Resampling**: Involves sampling particles according to their weights using multinomial distribution.
– **Residual Resampling**: Combines deterministic selection with stochastic selection.
– **Stratified Resampling**: Ensures that every particle has an equal chance by dividing weight space into strata.
Each strategy requires careful handling of numerical precision issues due to floating-point arithmetic.
### Extension
1. **Adaptive Resampling Threshold**: Introduce an adaptive threshold mechanism that decides when resampling should occur based on particle diversity.
– Calculate effective sample size (ESS) dynamically.
– Trigger resampling only when ESS falls below a certain threshold relative to `num_particles`.
2. **Dynamic Particle Count**: Allow dynamic adjustment of `num_particles` based on some criteria like computational budget or observed state complexity.
– Implement logic that increases/decreases `num_particles` adaptively.
3. **Weight Normalization Check**: Ensure robustness by adding checks that verify weight normalization after each update step.
4. **Integration with Observations**: Extend functionality so that particles can be updated based on new observations using Bayesian inference principles.
## Exercise
### Problem Statement:
Extend the given [SNIPPET] code by implementing additional functionalities:
1. Implement three different resampling strategies (`multinomial`, `residual`, `stratified`).
python
def resample(self):
if self.resampling_strat == 'multinomial':
return self._multinomial_resample()
elif self.resampling_strat == 'residual':
return self._residual_resample()
elif self.resampling_strat == 'stratified':
return self._stratified_resample()
else:
raise ValueError("Unknown resampling strategy")
def _multinomial_resample(self):
# Implement multinomial resampling here
def _residual_resample(self):
# Implement residual resampling here
def _stratified_resample(self):
# Implement stratified resampling here
### Requirements:
1. Add methods `_multinomial_resample()`, `_residual_resample()`, `_stratified_resample()` within `ParticleFilter` class.
– Use numpy functions efficiently.
– Ensure numerical stability especially when dealing with very small/large weights.
### Solution:
python
import numpy as np
class ParticleFilter(object):
def __init__(self,
num_particles=100,
init_particles=None,
resampling_strat='multinomial',
verbose=False):
"""
:param num_particles:

:param verbose:
"""
self.num_particles = num_particles
self.resampling_strat = resampling_strat.lower()
self.verbose = verbose
if init_particles is None:
self.particles = np.zeros((num_particles,))
self.weights = np.ones((num_particles,))
self.weights /= sum(self.weights)
else:
assert len(init_particles) == num_particles, "Initial particles count mismatch"
assert len(init_weights) == num_particles, "Initial weights count mismatch"
assert abs(sum(init_weights) -1) <= np.finfo(float).eps , "Weights must sum up to one"
self.particles = np.array(init_particles)
self.weights = np.array(init_weights)
def effective_sample_size(self):
return (np.sum(np.square(self.weights)))**(-1)
def normalize_weights(self):
total_weight = sum(self.weights)
if total_weight !=0 :
normalized_weights=self.weights/total_weight
else :
normalized_weights=np.ones_like(self.weights)/len(self.weights)
return normalized_weights
def _multinomial_resample(self):
indices = np.random.choice(
range(len(self.particles)), size=self.num_particles,
p=self.normalize_weights())
new_particles = [self.particles[i] for i in indices]

return new_particles,new_weights
def _residual_resample():

if n_eff<self.num_particle/5 :
indexes=np.zeros_like(particle_filter.particles)
num_copied=int(np.floor(particle_filter.num_particle*np.array(particle_filter.weight)))
base=np.cumsum(num_copied)-num_copied
residual_particle=particle_filter.particles.copy()[np.array(base,dtype=int)]
residual_weight=particle_filter.weight-residual_particle.astype(int)
residual_weight=residual_weight/sum(residual_weight)
indexes[:int(np.sum(num_copied))]=base.astype(int)
def _stratifed_resamble():
positions=(np.random.rand()+np.arange(0,self.num_particle))/self.num_particle
indexes=np.zeros_like(positions,dtype=int)
cumulative_sum=np.cumsum(particle_filter.weight)
i=0
j=0
while icumulative_sum[j]:
j+=1
if j==len(cumulative_sum):
j=len(cumulative_sum)-1
indexes[i]=j
i+=1
## Follow-up Exercise:
Implement an adaptive mechanism where you adjust `num_particle` dynamically based on computational budget constraints or observed state complexity:
* Increase particle count when variance among particle weights is high.
* Decrease particle count when variance among particle weights is low but keep it above a minimum threshold.
python
def adjust_num_particules_based_on_variance():
Implement a python module according to the following instructions:
## General functionality
The code provides utility functions for handling tensors within machine learning models built using TensorFlow/Keras frameworks. It includes functions for retrieving tensor outputs from layers given specific inputs or input keys, validating input shapes against expected model input shapes, and determining output keys from layers given specific inputs or input keys.
## Specifics and edge cases
– The function `_get_layer_outputs_from_inputs_or_input_keys` should handle two cases depending on whether input keys are provided along with inputs:
– If input keys are provided without actual inputs, it should raise an error indicating that both inputs and input keys must be provided together.
– If only inputs are provided without input keys, it should validate that each input corresponds to exactly one model input layer by shape compatibility; otherwise, it should raise an error indicating ambiguous matching between inputs and model inputs.
– The function `_validate_input_shapes_against_model_input_shapes` should compare each provided input shape with all model input shapes using broadcasting rules similar to those used by Keras backend functions like `K.expand_dims`. It should yield pairs of matched input shapes only if they are compatible according to these rules; otherwise, it should raise an error indicating incompatible shapes.
– The function `_get_output_keys_from_inputs_or_input_keys` should determine which output keys correspond to given inputs or input keys by traversing through layers connected via inbound nodes until it finds layers whose outputs match any of the model outputs.
## Programmatic aspects
– Use Python’s typing module for type annotations to clearly define expected argument types such as dictionaries mapping strings to tensors or lists thereof.
– Employ exception handling (`ValueError`) to manage error conditions such as missing arguments or incompatible shapes.
– Use generator expressions (`yield`) for efficient iteration over potentially large sets of data without needing intermediate storage.
– Utilize set operations for comparing collections of items such as output names from layers.
## Constants, data and tables
Not applicable; there are no hard-coded constants, tables, or lists specific to this code that need separate definition outside of standard library values.
## APIs and interfaces
The code interacts with TensorFlow/Keras APIs specifically:
– TensorFlow’s tensor manipulation functions such as `tf.shape`.
– Keras backend functions like `K.expand_dims`.
These interactions require familiarity with TensorFlow/Keras models’ structure and behavior.
## Extra details
– The code assumes that each layer has at most one inbound node per inbound connection (`assert len(layer.inbound_nodes) set[str]:
# Determine which output keys correspond…
pass # Placeholder implementation
# Example usage would be something like this:
# Assuming we have a Keras Model instance called my_model…
# my_model_outputs_names_set would be something like {‘output_0′, …}
# my_matched_inputs would be obtained via calling our function above…
# output_keys_for_my_matched_inputs would be obtained via calling our second function above…
**User:** I’d like you add caching mechanisms within `_get_layer_outputs_from_inputs_or_input_keys` so we don’t recompute outputs when called multiple times with identical arguments.
**Assistant:** To implement caching within `_get_layer_outputs_from_inputs_or_input_keys`, you can use functools’ `lru_cache`. Here’s how you can modify the function:
python
from functools import lru_cache
@lru_cache(maxsize=None) # Cache results indefinitely; remove maxsize parameter if you want unbounded cache size.
def _get_layer_outputs_from_inputs_or_input_keys_cached(model_hash:int,
serialized_inputs:str): # We need hashable arguments due to caching requirements.
# Convert serialized string back into actual objects inside this wrapper function…
pass # Placeholder implementation
# You will need a wrapper around your original function since lru_cache requires hashable arguments.
def get_layer_outputs_with_caching(model: Model,
*args,**kwargs): # args will contain either inputs alone or both inputs & input_keys together…
pass # Placeholder implementation including serialization/deserialization logic…
Remember that caching can lead to increased memory usage over time since cached results are stored until they’re evicted according to LRU policy.
**User:** Great! Now I want support for models where layers might have multiple inbound nodes per connection.
**Assistant:** To handle multiple inbound nodes per connection, you’ll need to adjust how you iterate over inbound nodes within your functions. Here’s what you could change:
python
# Inside your existing functions where you iterate over inbound nodes…
for layer_index,node_index,inbound_node_info,_outbound_node_index,_layer_inbound_index
,_node_inbound_index,_tensor_index,_tensor_slice
in node_to_layer_map.items():
inbound_layers=[model.get_layer(layer_info[‘inbound_layers’][i][0])
.input
.op.inputs[j]
.op
.outputs[k]
.name.split(‘/’)[0]
for i,j,k
in zip(node_info[‘inbound_layers’],node_info[‘tensor_indices’],node_info[‘tensor_slices’])]
assert len(inbound_layers)bool:
“””Custom validation logic.”””
if custom_validation_func is not None:
return custom_validation_func(input_shape[::-1], expected_shape[::-1])
else:
return all(i_dim == e_dim or i_dim is None or e_dim == None
for i_dim,e_dim in zip(input_shape[::-1],expected_shape[::-1]))
def _validate_input_shapes_against_model_input_shapes(input_shape:list[int],
expected_shapes_list:list[list[int]],
custom_validation_func=None)->Generator[list[int],None,None]:
“””Broadcasting rules similar…”””
yield from (
exp_shape
for exp_shape
in expected_shapes_list
if _validate_custom_logic(input_shape,
exp_shape,
custom_validation_func))
Now users can pass their own validation function when calling `_validate_input_shapes_against_model_input_shapes`. This function should accept two lists representing shapes and return a boolean indicating whether they’re considered compatible according to user-defined rules.Implement a python module according to the following instructions:
## General functionality
The code defines two classes intended for use within neural network architectures involving attention mechanisms. The first class implements multi-head attention pooling (MHAP), which aggregates information across different heads of an attention mechanism before combining them linearly with learned weights. The second class implements channel-wise attention pooling (CAP), which applies attention across channels after applying non-linear transformations followed by softmax normalization.
## Specifics and edge cases
### MultiHeadAttentionPooling Class:
– Initialize with parameters specifying dimensions (`dim_in`, `dim_out`), number of heads (`heads_count`), dropout rate (`dropout_rate`), activation type (`activation_type`), optional batch normalization flag (`use_bn`), optional dropout flag (`use_dropout`), optional last dimension flag (`last_dimension_only`), optional bias flag (`use_bias_last_linear_transformer`), optional pre-initialized linear transformation matrices (`first_linear_transformer_matrices`, `last_linear_transformer_matrixes`) along with corresponding biases (`first_linear_transformer_biases`, `last_linear_transformer_biases`). An optional device specification may also be provided; otherwise defaults determined by PyTorch will apply.
### ChannelAttentionPooling Class:
– Initialize similarly but only requires dimensions related specifically to channel attention pooling operations without heads count consideration since it operates channel-wise rather than head-wise.
For both classes:
– If pre-initialized transformation matrices/biases are not provided during initialization but flags indicating their use are set true without providing corresponding values raises exceptions ensuring consistency between configuration options chosen during initialization.
For MHAP forward operation specifics include handling cases where either first linear transformer matrices/biases are not used but last ones are initialized incorrectly leading again raising exceptions ensuring consistency between configuration options chosen during initialization.
For CAP forward operation specifics include reshaping operations necessary before applying non-linear transformations followed by softmax normalization across channels.
In both classes’ forward methods ensure correct tensor reshaping operations before returning final pooled output.
## Programmatic aspects used include object-oriented programming principles defining classes with encapsulated attributes/methods relevant specifically towards multi-head attention pooling functionality.
Error checking through assertions ensuring consistency between various configuration options chosen during initialization.
Use PyTorch library functionalities extensively including tensor operations such as reshaping/viewing tensors differently based on context-specific requirements.
Use PyTorch modules such as DropoutLayerWrapper encapsulating dropout functionality.
Use conditional statements extensively throughout forward methods adapting behavior dynamically based upon configuration flags set during initialization.
* Make sure to implement at least ( frac{N}{4} ) distinct extensions suggested above.
Here’s a basic implementation outline:

## Challenging Aspects
### Challenging Aspects in Above Code
1. **Resampling Strategies**: Implementing different resampling strategies (`multinomial`, `residual`, `stratified`) requires understanding each strategy's mathematical foundation. Each strategy affects how particles are selected based on weights differently.
– **Multinomial Resampling**: Involves sampling particles according to their weights using multinomial distribution.
– **Residual Resampling**: Combines deterministic selection with stochastic selection.
– **Stratified Resampling**: Ensures that every particle has an equal chance by dividing weight space into strata.
Each strategy requires careful handling of numerical precision issues due to floating-point arithmetic.
### Extension
1. **Adaptive Resampling Threshold**: Introduce an adaptive threshold mechanism that decides when resampling should occur based on particle diversity.
– Calculate effective sample size (ESS) dynamically.
– Trigger resampling only when ESS falls below a certain threshold relative to `num_particles`.
2. **Dynamic Particle Count**: Allow dynamic adjustment of `num_particles` based on some criteria like computational budget or observed state complexity.
– Implement logic that increases/decreases `num_particles` adaptively.
3. **Weight Normalization Check**: Ensure robustness by adding checks that verify weight normalization after each update step.
4. **Integration with Observations**: Extend functionality so that particles can be updated based on new observations using Bayesian inference principles.
## Exercise
### Problem Statement:
Extend the given [SNIPPET] code by implementing additional functionalities:
1. Implement three different resampling strategies (`multinomial`, `residual`, `stratified`).
python
def resample(self):
if self.resampling_strat == 'multinomial':
return self._multinomial_resample()
elif self.resampling_strat == 'residual':
return self._residual_resample()
elif self.resampling_strat == 'stratified':
return self._stratified_resample()
else:
raise ValueError("Unknown resampling strategy")
def _multinomial_resample(self):
# Implement multinomial resampling here
def _residual_resample(self):
# Implement residual resampling here
def _stratified_resample(self):
# Implement stratified resampling here
### Requirements:
1. Add methods `_multinomial_resample()`, `_residual_resample()`, `_stratified_resample()` within `ParticleFilter` class.
– Use numpy functions efficiently.
– Ensure numerical stability especially when dealing with very small/large weights.
### Solution:
python
import numpy as np
class ParticleFilter(object):
def __init__(self,
num_particles=100,
init_particles=None,
resampling_strat='multinomial',
verbose=False):
"""

:param verbose:
"""
self.num_particles = num_particles
self.resampling_strat = resampling_strat.lower()
self.verbose = verbose
if init_particles is None:
self.particles = np.zeros((num_particles,))
self.weights = np.ones((num_particles,))
self.weights /= sum(self.weights)
else:
assert len(init_particles) == num_particles, "Initial particles count mismatch"
assert len(init_weights) == num_particles, "Initial weights count mismatch"
assert abs(sum(init_weights) -1) <= np.finfo(float).eps , "Weights must sum up to one"
self.particles = np.array(init_particles)
self.weights = np.array(init_weights)
def effective_sample_size(self):
return (np.sum(np.square(self.weights)))**(-1)
def normalize_weights(self):
total_weight = sum(self.weights)
if total_weight !=0 :
normalized_weights=self.weights/total_weight
else :
normalized_weights=np.ones_like(self.weights)/len(self.weights)
return normalized_weights
def _multinomial_resample(self):
indices = np.random.choice(
range(len(self.particles)), size=self.num_particles,
p=self.normalize_weights())
new_particles = [self.particles[i] for i in indices]

if n_eff<self.num_particle/5 :
indexes=np.zeros_like(particle_filter.particles)
num_copied=int(np.floor(particle_filter.num_particle*np.array(particle_filter.weight)))
base=np.cumsum(num_copied)-num_copied
residual_particle=particle_filter.particles.copy()[np.array(base,dtype=int)]
residual_weight=particle_filter.weight-residual_particle.astype(int)
residual_weight=residual_weight/sum(residual_weight)
indexes[:int(np.sum(num_copied))]=base.astype(int)
def _stratifed_resamble():
positions=(np.random.rand()+np.arange(0,self.num_particle))/self.num_particle
indexes=np.zeros_like(positions,dtype=int)
cumulative_sum=np.cumsum(particle_filter.weight)
i=0
j=0
while icumulative_sum[j]:
j+=1
if j==len(cumulative_sum):
j=len(cumulative_sum)-1
indexes[i]=j
i+=1
## Follow-up Exercise:
Implement an adaptive mechanism where you adjust `num_particle` dynamically based on computational budget constraints or observed state complexity:
* Increase particle count when variance among particle weights is high.
* Decrease particle count when variance among particle weights is low but keep it above a minimum threshold.
python
def adjust_num_particules_based_on_variance():
Implement a python module according to the following instructions:
## General functionality
The code provides utility functions for handling tensors within machine learning models built using TensorFlow/Keras frameworks. It includes functions for retrieving tensor outputs from layers given specific inputs or input keys, validating input shapes against expected model input shapes, and determining output keys from layers given specific inputs or input keys.
## Specifics and edge cases
– The function `_get_layer_outputs_from_inputs_or_input_keys` should handle two cases depending on whether input keys are provided along with inputs:
– If input keys are provided without actual inputs, it should raise an error indicating that both inputs and input keys must be provided together.
– If only inputs are provided without input keys, it should validate that each input corresponds to exactly one model input layer by shape compatibility; otherwise, it should raise an error indicating ambiguous matching between inputs and model inputs.
– The function `_validate_input_shapes_against_model_input_shapes` should compare each provided input shape with all model input shapes using broadcasting rules similar to those used by Keras backend functions like `K.expand_dims`. It should yield pairs of matched input shapes only if they are compatible according to these rules; otherwise, it should raise an error indicating incompatible shapes.
– The function `_get_output_keys_from_inputs_or_input_keys` should determine which output keys correspond to given inputs or input keys by traversing through layers connected via inbound nodes until it finds layers whose outputs match any of the model outputs.
## Programmatic aspects
– Use Python’s typing module for type annotations to clearly define expected argument types such as dictionaries mapping strings to tensors or lists thereof.
– Employ exception handling (`ValueError`) to manage error conditions such as missing arguments or incompatible shapes.
– Use generator expressions (`yield`) for efficient iteration over potentially large sets of data without needing intermediate storage.
– Utilize set operations for comparing collections of items such as output names from layers.
## Constants, data and tables
Not applicable; there are no hard-coded constants, tables, or lists specific to this code that need separate definition outside of standard library values.
## APIs and interfaces
The code interacts with TensorFlow/Keras APIs specifically:
– TensorFlow’s tensor manipulation functions such as `tf.shape`.
– Keras backend functions like `K.expand_dims`.
These interactions require familiarity with TensorFlow/Keras models’ structure and behavior.
## Extra details
– The code assumes that each layer has at most one inbound node per inbound connection (`assert len(layer.inbound_nodes) set[str]:
# Determine which output keys correspond…
pass # Placeholder implementation
# Example usage would be something like this:
# Assuming we have a Keras Model instance called my_model…
# my_model_outputs_names_set would be something like {‘output_0′, …}
# my_matched_inputs would be obtained via calling our function above…
# output_keys_for_my_matched_inputs would be obtained via calling our second function above…
**User:** I’d like you add caching mechanisms within `_get_layer_outputs_from_inputs_or_input_keys` so we don’t recompute outputs when called multiple times with identical arguments.
**Assistant:** To implement caching within `_get_layer_outputs_from_inputs_or_input_keys`, you can use functools’ `lru_cache`. Here’s how you can modify the function:
python
from functools import lru_cache
@lru_cache(maxsize=None) # Cache results indefinitely; remove maxsize parameter if you want unbounded cache size.
def _get_layer_outputs_from_inputs_or_input_keys_cached(model_hash:int,
serialized_inputs:str): # We need hashable arguments due to caching requirements.
# Convert serialized string back into actual objects inside this wrapper function…
pass # Placeholder implementation
# You will need a wrapper around your original function since lru_cache requires hashable arguments.
def get_layer_outputs_with_caching(model: Model,
*args,**kwargs): # args will contain either inputs alone or both inputs & input_keys together…
pass # Placeholder implementation including serialization/deserialization logic…
Remember that caching can lead to increased memory usage over time since cached results are stored until they’re evicted according to LRU policy.
**User:** Great! Now I want support for models where layers might have multiple inbound nodes per connection.
**Assistant:** To handle multiple inbound nodes per connection, you’ll need to adjust how you iterate over inbound nodes within your functions. Here’s what you could change:
python
# Inside your existing functions where you iterate over inbound nodes…
for layer_index,node_index,inbound_node_info,_outbound_node_index,_layer_inbound_index
,_node_inbound_index,_tensor_index,_tensor_slice
in node_to_layer_map.items():
inbound_layers=[model.get_layer(layer_info[‘inbound_layers’][i][0])
.input
.op.inputs[j]
.op
.outputs[k]
.name.split(‘/’)[0]
for i,j,k
in zip(node_info[‘inbound_layers’],node_info[‘tensor_indices’],node_info[‘tensor_slices’])]
assert len(inbound_layers)bool:
“””Custom validation logic.”””
if custom_validation_func is not None:
return custom_validation_func(input_shape[::-1], expected_shape[::-1])
else:
return all(i_dim == e_dim or i_dim is None or e_dim == None
for i_dim,e_dim in zip(input_shape[::-1],expected_shape[::-1]))
def _validate_input_shapes_against_model_input_shapes(input_shape:list[int],
expected_shapes_list:list[list[int]],
custom_validation_func=None)->Generator[list[int],None,None]:
“””Broadcasting rules similar…”””
yield from (
exp_shape
for exp_shape
in expected_shapes_list
if _validate_custom_logic(input_shape,
exp_shape,
custom_validation_func))
Now users can pass their own validation function when calling `_validate_input_shapes_against_model_input_shapes`. This function should accept two lists representing shapes and return a boolean indicating whether they’re considered compatible according to user-defined rules.Implement a python module according to the following instructions:
## General functionality
The code defines two classes intended for use within neural network architectures involving attention mechanisms. The first class implements multi-head attention pooling (MHAP), which aggregates information across different heads of an attention mechanism before combining them linearly with learned weights. The second class implements channel-wise attention pooling (CAP), which applies attention across channels after applying non-linear transformations followed by softmax normalization.
## Specifics and edge cases
### MultiHeadAttentionPooling Class:
– Initialize with parameters specifying dimensions (`dim_in`, `dim_out`), number of heads (`heads_count`), dropout rate (`dropout_rate`), activation type (`activation_type`), optional batch normalization flag (`use_bn`), optional dropout flag (`use_dropout`), optional last dimension flag (`last_dimension_only`), optional bias flag (`use_bias_last_linear_transformer`), optional pre-initialized linear transformation matrices (`first_linear_transformer_matrices`, `last_linear_transformer_matrixes`) along with corresponding biases (`first_linear_transformer_biases`, `last_linear_transformer_biases`). An optional device specification may also be provided; otherwise defaults determined by PyTorch will apply.
### ChannelAttentionPooling Class:
– Initialize similarly but only requires dimensions related specifically to channel attention pooling operations without heads count consideration since it operates channel-wise rather than head-wise.
For both classes:
– If pre-initialized transformation matrices/biases are not provided during initialization but flags indicating their use are set true without providing corresponding values raises exceptions ensuring consistency between configuration options chosen during initialization.
For MHAP forward operation specifics include handling cases where either first linear transformer matrices/biases are not used but last ones are initialized incorrectly leading again raising exceptions ensuring consistency between configuration options chosen during initialization.
For CAP forward operation specifics include reshaping operations necessary before applying non-linear transformations followed by softmax normalization across channels.
In both classes’ forward methods ensure correct tensor reshaping operations before returning final pooled output.
## Programmatic aspects used include object-oriented programming principles defining classes with encapsulated attributes/methods relevant specifically towards multi-head attention pooling functionality.
Error checking through assertions ensuring consistency between various configuration options chosen during initialization.
Use PyTorch library functionalities extensively including tensor operations such as reshaping/viewing tensors differently based on context-specific requirements.
Use PyTorch modules such as DropoutLayerWrapper encapsulating dropout functionality.
Use conditional statements extensively throughout forward methods adapting behavior dynamically based upon configuration flags set during initialization.
* Make sure to implement at least ( frac{N}{4} ) distinct extensions suggested above.
Here’s a basic implementation outline:
python
import torch.nn.functional as F
class MultiHeadAttentionPooling(nn.Module):
class ChannelAttentionPooling(nn.Module):
Implement a python module according t othe following specifications:
* DO NOT create placeholders for various logic. Instead write the complete code including the logic. If the logic is unclear or very complicate,
* Try t otest th e code thoroughly

Add methods `_multinomial_resample()`, `_residual_resample()`, `_stratified_resample()` within `ParticleFilter` class. – Use numpy functions efficiently. – Ensure numerical stability especially when dealing with very small/large weights. ### Solution: python import numpy as np class ParticleFilter(object): def __init__(self, num_particles=100, init_particles=None, resampling_strat='multinomial', verbose=False): """ :param num_particles: :param init_particles: :param resampling_strat: 'multinomial', 'residual', 'stratified' :param verbose: """ self.num_particles = num_particles self.resampling_strat = resampling_strat.lower() self.verbose = verbose if init_particles is None: self.particles = np.zeros((num_particles,)) self.weights = np.ones((num_particles,)) self.weights /= sum(self.weights) else: assert len(init_particles) == num_particles, "Initial particles count mismatch" assert len(init_weights) == num_particles, "Initial weights count mismatch" assert abs(sum(init_weights) -1) <= np.finfo(float).eps , "Weights must sum up to one" self.particles = np.array(init_particles) self.weights = np.array(init_weights) def effective_sample_size(self): return (np.sum(np.square(self.weights)))**(-1) def normalize_weights(self): total_weight = sum(self.weights) if total_weight !=0 : normalized_weights=self.weights/total_weight else : normalized_weights=np.ones_like(self.weights)/len(self.weights) return normalized_weights def _multinomial_resample(self): indices = np.random.choice( range(len(self.particles)), size=self.num_particles, p=self.normalize_weights()) new_particles = [self.particles[i] for i in indices] new_weights=np.ones_like(new_particles)/len(new_particles) return new_particles,new_weights def _residual_resample(): n_eff=self.effective_sample_size() if n_eff<self.num_particle/5 : indexes=np.zeros_like(particle_filter.particles) num_copied=int(np.floor(particle_filter.num_particle*np.array(particle_filter.weight))) base=np.cumsum(num_copied)-num_copied residual_particle=particle_filter.particles.copy()[np.array(base,dtype=int)] residual_weight=particle_filter.weight-residual_particle.astype(int) residual_weight=residual_weight/sum(residual_weight) indexes[:int(np.sum(num_copied))]=base.astype(int) def _stratifed_resamble(): positions=(np.random.rand()+np.arange(0,self.num_particle))/self.num_particle indexes=np.zeros_like(positions,dtype=int) cumulative_sum=np.cumsum(particle_filter.weight) i=0 j=0 while icumulative_sum[j]: j+=1 if j==len(cumulative_sum): j=len(cumulative_sum)-1 indexes[i]=j i+=1 ## Follow-up Exercise: Implement an adaptive mechanism where you adjust `num_particle` dynamically based on computational budget constraints or observed state complexity: * Increase particle count when variance among particle weights is high. * Decrease particle count when variance among particle weights is low but keep it above a minimum threshold. python def adjust_num_particules_based_on_variance(): Implement a python module according to the following instructions: ## General functionality The code provides utility functions for handling tensors within machine learning models built using TensorFlow/Keras frameworks. It includes functions for retrieving tensor outputs from layers given specific inputs or input keys, validating input shapes against expected model input shapes, and determining output keys from layers given specific inputs or input keys. ## Specifics and edge cases – The function `_get_layer_outputs_from_inputs_or_input_keys` should handle two cases depending on whether input keys are provided along with inputs: – If input keys are provided without actual inputs, it should raise an error indicating that both inputs and input keys must be provided together. – If only inputs are provided without input keys, it should validate that each input corresponds to exactly one model input layer by shape compatibility; otherwise, it should raise an error indicating ambiguous matching between inputs and model inputs. – The function `_validate_input_shapes_against_model_input_shapes` should compare each provided input shape with all model input shapes using broadcasting rules similar to those used by Keras backend functions like `K.expand_dims`. It should yield pairs of matched input shapes only if they are compatible according to these rules; otherwise, it should raise an error indicating incompatible shapes. – The function `_get_output_keys_from_inputs_or_input_keys` should determine which output keys correspond to given inputs or input keys by traversing through layers connected via inbound nodes until it finds layers whose outputs match any of the model outputs. ## Programmatic aspects – Use Python’s typing module for type annotations to clearly define expected argument types such as dictionaries mapping strings to tensors or lists thereof. – Employ exception handling (`ValueError`) to manage error conditions such as missing arguments or incompatible shapes. – Use generator expressions (`yield`) for efficient iteration over potentially large sets of data without needing intermediate storage. – Utilize set operations for comparing collections of items such as output names from layers. ## Constants, data and tables Not applicable; there are no hard-coded constants, tables, or lists specific to this code that need separate definition outside of standard library values. ## APIs and interfaces The code interacts with TensorFlow/Keras APIs specifically: – TensorFlow’s tensor manipulation functions such as `tf.shape`. – Keras backend functions like `K.expand_dims`. These interactions require familiarity with TensorFlow/Keras models’ structure and behavior. ## Extra details – The code assumes that each layer has at most one inbound node per inbound connection (`assert len(layer.inbound_nodes) set[str]: # Determine which output keys correspond… pass # Placeholder implementation # Example usage would be something like this: # Assuming we have a Keras Model instance called my_model… # my_model_outputs_names_set would be something like {‘output_0′, …} # my_matched_inputs would be obtained via calling our function above… # output_keys_for_my_matched_inputs would be obtained via calling our second function above… **User:** I’d like you add caching mechanisms within `_get_layer_outputs_from_inputs_or_input_keys` so we don’t recompute outputs when called multiple times with identical arguments. **Assistant:** To implement caching within `_get_layer_outputs_from_inputs_or_input_keys`, you can use functools’ `lru_cache`. Here’s how you can modify the function: python from functools import lru_cache @lru_cache(maxsize=None) # Cache results indefinitely; remove maxsize parameter if you want unbounded cache size. def _get_layer_outputs_from_inputs_or_input_keys_cached(model_hash:int, serialized_inputs:str): # We need hashable arguments due to caching requirements. # Convert serialized string back into actual objects inside this wrapper function… pass # Placeholder implementation # You will need a wrapper around your original function since lru_cache requires hashable arguments. def get_layer_outputs_with_caching(model: Model, *args,**kwargs): # args will contain either inputs alone or both inputs & input_keys together… pass # Placeholder implementation including serialization/deserialization logic… Remember that caching can lead to increased memory usage over time since cached results are stored until they’re evicted according to LRU policy. **User:** Great! Now I want support for models where layers might have multiple inbound nodes per connection. **Assistant:** To handle multiple inbound nodes per connection, you’ll need to adjust how you iterate over inbound nodes within your functions. Here’s what you could change: python # Inside your existing functions where you iterate over inbound nodes… for layer_index,node_index,inbound_node_info,_outbound_node_index,_layer_inbound_index ,_node_inbound_index,_tensor_index,_tensor_slice in node_to_layer_map.items(): inbound_layers=[model.get_layer(layer_info[‘inbound_layers’][i][0]) .input .op.inputs[j] .op .outputs[k] .name.split(‘/’)[0] for i,j,k in zip(node_info[‘inbound_layers’],node_info[‘tensor_indices’],node_info[‘tensor_slices’])] assert len(inbound_layers)bool: “””Custom validation logic.””” if custom_validation_func is not None: return custom_validation_func(input_shape[::-1], expected_shape[::-1]) else: return all(i_dim == e_dim or i_dim is None or e_dim == None for i_dim,e_dim in zip(input_shape[::-1],expected_shape[::-1])) def _validate_input_shapes_against_model_input_shapes(input_shape:list[int], expected_shapes_list:list[list[int]], custom_validation_func=None)->Generator[list[int],None,None]: “””Broadcasting rules similar…””” yield from ( exp_shape for exp_shape in expected_shapes_list if _validate_custom_logic(input_shape, exp_shape, custom_validation_func)) Now users can pass their own validation function when calling `_validate_input_shapes_against_model_input_shapes`. This function should accept two lists representing shapes and return a boolean indicating whether they’re considered compatible according to user-defined rules.Implement a python module according to the following instructions: ## General functionality The code defines two classes intended for use within neural network architectures involving attention mechanisms. The first class implements multi-head attention pooling (MHAP), which aggregates information across different heads of an attention mechanism before combining them linearly with learned weights. The second class implements channel-wise attention pooling (CAP), which applies attention across channels after applying non-linear transformations followed by softmax normalization. ## Specifics and edge cases ### MultiHeadAttentionPooling Class: – Initialize with parameters specifying dimensions (`dim_in`, `dim_out`), number of heads (`heads_count`), dropout rate (`dropout_rate`), activation type (`activation_type`), optional batch normalization flag (`use_bn`), optional dropout flag (`use_dropout`), optional last dimension flag (`last_dimension_only`), optional bias flag (`use_bias_last_linear_transformer`), optional pre-initialized linear transformation matrices (`first_linear_transformer_matrices`, `last_linear_transformer_matrixes`) along with corresponding biases (`first_linear_transformer_biases`, `last_linear_transformer_biases`). An optional device specification may also be provided; otherwise defaults determined by PyTorch will apply. ### ChannelAttentionPooling Class: – Initialize similarly but only requires dimensions related specifically to channel attention pooling operations without heads count consideration since it operates channel-wise rather than head-wise. For both classes: – If pre-initialized transformation matrices/biases are not provided during initialization but flags indicating their use are set true without providing corresponding values raises exceptions ensuring consistency between configuration options chosen during initialization. For MHAP forward operation specifics include handling cases where either first linear transformer matrices/biases are not used but last ones are initialized incorrectly leading again raising exceptions ensuring consistency between configuration options chosen during initialization. For CAP forward operation specifics include reshaping operations necessary before applying non-linear transformations followed by softmax normalization across channels. In both classes’ forward methods ensure correct tensor reshaping operations before returning final pooled output. ## Programmatic aspects used include object-oriented programming principles defining classes with encapsulated attributes/methods relevant specifically towards multi-head attention pooling functionality. Error checking through assertions ensuring consistency between various configuration options chosen during initialization. Use PyTorch library functionalities extensively including tensor operations such as reshaping/viewing tensors differently based on context-specific requirements. Use PyTorch modules such as DropoutLayerWrapper encapsulating dropout functionality. Use conditional statements extensively throughout forward methods adapting behavior dynamically based upon configuration flags set during initialization. * Make sure to implement at least ( frac{N}{4} ) distinct extensions suggested above. Here’s a basic implementation outline: python import torch.nn.functional as F class MultiHeadAttentionPooling(nn.Module): class ChannelAttentionPooling(nn.Module): Implement a python module according t othe following specifications: * DO NOT create placeholders for various logic.
