## Suggestions for complexity
1. **Adaptive Bin Sizing:** Implement adaptive bin sizing based on quantiles instead of fixed-size bins.
2. **Weighted True Positive Rate:** Modify `true_positive_rate` calculation by incorporating sample weights.
3. **Parallel Processing:** Optimize loop calculations using parallel processing techniques such as multiprocessing or joblib.
4. **Handling Missing Values:** Enhance robustness by handling missing values within `y_true` or `y_prob`.
5. **Dynamic Threshold Calculation:** Use more sophisticated methods like ROC curve analysis instead of mean probability threshold.
## Conversation
<|user|>"I need help with this piece code [SNIPPET]. I want more dynamic threshold calc not just mean prob"<|end|>
<|assistant|>"Sure! Instead of using mean probability as threshold we can use median absolute deviation (MAD) or even ROC curve analysis method like Youden's J statistic.
Here's how you can modify it:
python
from sklearn.metrics import roc_curve
def plot_calibration_curve(y_true,y_prob):
if isinstance(y_prob,list):
n_bins = len(y_prob)
# calculate true positive rate per bin
true_positive_rate = []
thresholds = []
# Calculate ROC curve points
fpr, tpr, roc_thresholds = roc_curve(y_true.flatten(), np.concatenate(y_prob).flatten())
j_scores = tpr - fpr
best_threshold_index = np.argmax(j_scores)
best_thresholds_per_bin = []
# Loop over each bin
for i in range(n_bins):
y_bin_probs = np.array(y_prob[i])
optimal_threshold_index_per_bin = np.argmin(np.abs(roc_thresholds - np.median(y_bin_probs)))
best_thresholds_per_bin.append(roc_thresholds[optimal_threshold_index_per_bin])
thresholds.append(best_thresholds_per_bin[-1])
pred_positives = np.where(np.array(y_bin_probs) >= thresholds[-1])[0]
true_positive_rate.append(len(np.intersect1d(pred_positives,np.where(np.array(y_true)>=thresholds[-1])[0])) / len(pred_positives))
This uses ROC curve analysis to determine optimal threshold dynamically.<|end|>
<|user|>"How add sample weight? Need weighted TPR"<|end|>
<|assistant|>"To incorporate sample weights into your TPR calculation:
python
def plot_calibration_curve_weighted(y_true,y_prob,sample_weights):
if isinstance(y_prob,list):
n_bins = len(y_prob)
# calculate weighted true positive rate per bin
weighted_true_positive_rate = []
thresholds=[]
# Calculate ROC curve points
fpr,tpr,_=roc_curve(np.concatenate([np.ones_like(p) if w > .5 else -np.ones_like(p)for p,w in zip(*zip(*[(yp,pw)for yp,pw in zip(*zip(*[(yp,pw)for yp,pw in zip(*(y_true,y_prob)]))])])]),np.concatenate([pw*np.ones_like(p)for p,pw in zip(*zip(*[(yp,pw)for yp,pw in zip(*(y_true,y_prob)]))]),sample_weight=np.concatenate(sample_weights))
j_scores=tpr-fpr
best_threshold_index=np.argmax(j_scores)
best_thresholds_per_bin=[]
total_weights=[]
# Loop over each bin
for i in range(n_bins):
y_bin_probs=np.array(y_prob[i])
sample_weight_i=np.array(sample_weights[i])
optimal_threshold_index_per_bin=np.argmin(np.abs(fpr - np.median(fpr)))
best_thresholds_per_bin.append(fpr[optimal_threshold_index_per_bin])
thresholds.append(best_thresholds_per_bin[-1])
pred_positives=np.where(np.array(y_bin_probs)>=thresholds[-1])[0]
tp_weight=sum(sample_weight_i[np.isin(pred_positives,np.where(np.array((y_true>=thresholds[-1])))[0])])
fp_weight=sum(sample_weight_i[np.isin(pred_positives,np.where(np.array((y_true
0 else float('nan') weighted_true_positive_rate.append(weighted_tpr) Here we pass `sample_weights` along with `y_true` & `y_prob`. We then compute weighted TPR accordingly.<|end|> <|user|>"Can optimize loop parallel? Make faster"<|end|> <|assistant|>"Sure! We can use Python's multiprocessing library to parallelize the loop computation: python import numpy as np from sklearn.metrics import roc_curve from multiprocessing import Pool def compute_metrics(args): y_bin_probs, y_true_thresh_idx_list,i= args pred_positives=np.where(np.array((y_bin_probs)>=i))[0] tp=len(np.intersect1d(pred_positives,y_true_thresh_idx_list)) return tp,len(pred_positives) def plot_calibration_curve_parallelized_youden_j_statistic_method_implementation_optimized_version_of_the_above_code_that_is_faster_than_the_original_code_(y_true,y_pred): if isinstance(list_of_probability_lists,list): n_bins=len(list_of_probability_lists) fpr,tpr,_=roc_curve((np.concatenate(list_of_probability_lists)),np.concatenate([list_of_sample_weights])) j_scores=tpr-fpr best_thresh_indice=np.argmax(j_scores) optimal_thresh=fprs[j_indices] bins_metrics=[] with Pool() as pool: bins_metrics=pool.map(compute_metrics,[ (list_of_probability_lists[i],np.where((np.array((list_of_probability_lists))>=optimal_thresh[i])),optimal_thresh[i])for i,optimal_thresh_idx,optimal_thresh_val_in_each_iteration_in_loop_over_all_the_binnings_in_which_we_will_compute_the_performance_measures_in_order_to_find_out_how_good_the_model_performance_is_for_each_binning_which_is_done_by_using_the_optimized_version_of_the_above_code_that_is_faster_than_the_original_code_() ]) true_positive_rates=[tp/ratio if ratio!=0 else float('nan')for tp,ratio in bins_metrics] return bins_metrics,true_positive_rates,fprs,best_thresh_indice,j_scores,fprs,optimal_thresh In this version we use Python's multiprocessing library (`Pool`) which allows us run our function (`compute_metrics`) concurrently across multiple processors.
The function takes three arguments `(bin_probs,true_thres_idx_list,i)` where `bin_probs` is list containing probabilities corresponding to each bin; `true_thres_idx_list` contains indices corresponding to all instances whose predicted probabilities exceed given threshold value; finally parameter `i` represents current iteration number out-of-total number-of-bins-in-the-loop.
We then call our function via map method provided by pool object created earlier so that all iterations happen concurrently rather than sequentially resulting faster execution time compared-to-original-code!
<>: Hi there! I'm working on implementing Tarjan's algorithm for finding strongly connected components (SCCs) using PyTorch tensors instead of lists or arrays typically used with integers or floats. Here's my current implementation: python class TarjanClass: # Constructor: def __init__(self): self.NIL,self.index,self.stack,self.lowlink,self.onstack,self.indexCounter,self.sccResult=[-1]*10,[0]*N,[0]*N,[0]*N,[False]*N,0,[[]] # Finds SCCS via Tarjan Algorithm O(N+E) def SCC(self,G): # G must be represented by an Adjacency List for node in range(N): if not self.index[node]: self.Tarjan(G,node) return self.sccResult def Tarjan(self,G,node): self.index[node],self.lowlink[node],self.stack[self.indexCounter]=self.indexCounter,self.indexCounter,self.indexCounter, self.indexCounter+=1; self.onstack[node]=True; for child_ in G[node]: if not self.index[child_]: self.Tarjan(G,child_) self.lowlink[node]=min(self.lowlink[node],self.lowlink[child_]) elif self.onstack[child_]: self.lowlink[node]=min(self.lowlink[node],self.index[child_]) if self.lowlink[node]==self.index[node]: sccComponent=[] while True: node_,_=self.stack[self.indexCounter]; self.onstack[node_]=False; sccComponent+=[node_]; self.indexCounter-=1; if node_==node: break; sccComponent.sort(); self.sccResult+=[sccComponent[:]] However, when I run it with some test graphs represented as adjacency lists using PyTorch tensors instead of lists or arrays traditionally used with integers or floats only (e.g., [[tensor([item]),tensor([item]),...],[tensor([item]),tensor([item]),...],...]), I get an error related to indexing operations. Here is my traceback: Traceback (most recent call last): File "tarjan.py", line X.XX,in SCCClass.SCC(G) File "tarjan.py", line X.XX,in SCCClass.Tarjan(G,node) IndexError Traceback (most recent call last) File "tarjan.py", line X.XX,in SCCClass.SCC(G) File "tarjan.py", line X.XX,in SCCClass.Tarjan(G,node) IndexError:index out of bounds 'index' I suspect it has something do do with how PyTorch tensors handle indexing differently than traditional lists but I'm not entirely sure what adjustments need to be made here. Could someone please help me figure out what might be going wrong? Thanks! < >: python It looks like you're encountering issues due to differences between PyTorch tensor operations and traditional list indexing. Here are some suggestions to address these issues: 1. **Tensor Indexing**: Ensure you're using tensor-specific methods like `.item()` when extracting scalar values from tensors during indexing operations. 2. **Initialization**: When initializing arrays like `self.NIL`, ensure they match your graph size `N`. If `N` is dynamic based on input size, initialize them accordingly. 3. **Indexing Operations**: Replace direct list indexing with tensor operations where necessary. For example: - Use `.tolist()` or `.numpy()` if you need Python native types. - Use `.item()` when accessing single elements from tensors. Here's a revised snippet focusing on these points: python class TarjanClass: def __init__(self, N): self.NIL=self.index=self.stack=self.lowlink=self.onstack=[torch.tensor([-1])] * N + [torch.tensor(0)] self.indexCounter=self.sccResult=torch.tensor(0),[] def SCC(self,G): for node in range(len(G)): if not self.index[node].item(): self.Tarjan(G,node) return self.sccResult def Tarjan(self,G,node): self.index[node] = torch.tensor(self.indexCounter.item()) self.lowlink[node] = torch.tensor(self.indexCounter.item()) self.stack[self.indexCounter] = node self.indexCounter += 1 self.onstack[node] = True for child_tensor in G[node]: child_ = child_tensor.item() if not self.index[child_].item(): self.Tarjan(G,child_) self.lowlink[node] = min(self.lowlink[node], self.lowlink[child_]) elif self.onstack[child_]: self.lowlink[node] = min(self.lowlink[node], self.index[child_]) if self.lowlink[node].item() == self.index[node].item(): sccComponent=[] while True: node_, _= self.stack[self.indexCounter.item()], None node__=node_.item() self.onstack[node__]=False sccComponent+=[node__] self.indexCounter -= torch.tensor(1) if node__ == node: break sccComponent.sort() sccComponentTensor=torch.tensor(sccComponent[:]) self.sccResult += [sccComponentTensor.tolist()] Make sure you adapt any other parts of your code similarly where tensor operations might differ from list operations. Let me know if you need further assistance! 😊 < >: Thanks for the suggestions! I think I need to further optimize how I'm handling tensor operations within loops and conditionals. Right now, it seems like there might be unnecessary conversions between tensors and native types that could slow things down or cause errors. For instance, should I avoid using `.item()` repeatedly inside loops? And maybe there's a way to handle tensor updates more efficiently without converting back and forth? Any tips on optimizing these parts would be great! < >Certainly! Optimizing tensor operations involves minimizing conversions between tensors and native types within loops and conditionals. Here are some tips: ### Avoid Repeated Conversions - **Batch Operations**: Try performing operations directly on tensors rather than converting them individually using `.item()`. This leverages PyTorch's optimized backend. - **Conditional Logic**: Use tensor operations like logical indexing instead of iterating through elements individually. ### Efficient Tensor Updates - **In-place Operations**: Use in-place operations (e.g., `add_`, `mul_`) where possible to reduce memory overhead. - **Avoid Unnecessary Copies**: Be mindful of creating unnecessary copies during assignments or updates. ### Example Adjustments Here’s how you might adjust parts of your code: python class TarjanClass: def __init__(self, N): NIL_value_tensor=torch.full((N,), -1) tensor_zero=torch.zeros(N) self.NIL=self.NIL_value_tensor.clone() self.index=self.NIL_value_tensor.clone() self.stack=tensor_zero.clone() self.lowlink=tensor_zero.clone() onstack_mask=torch.zeros(N).bool() tensor_counter=torch.zeros((), dtype=torch.int64) def SCC(self,G): index_mask=(self.index == NIL_value_tensor).all(dim=-1) nodes_to_process=index_mask.nonzero(as_tuple=True)[0] while nodes_to_process.numel() > 0: node=nodes_to_process.pop(-dim=-len(nodes_to_process)) if index_mask.all(): continue self.Tarjan(G,node.item()) index_mask=(self.index == NIL_value_tensor).all(dim=-dim=-len(index_mask)) return [component.tolist() for component in self.sccResult] def Tarjan(self,G,node): index_node=self.get_or_update_index(node) low_link_node=index_node.clone() stack_node=self.update_stack(index_node) stack_top_index+=torch.ones(()) stack_top_onstack=True children=G[index_node] while children.numel()>0: child_=children.pop(-dim=-len(children)) child_index=self.get_or_update_index(child_) if child_index==-torch.ones(()): low_link_node=min(low_link_node,self.get_low_link(child_.clone())) elif stack_top_onstack[child_.clone().long()]: low_link_node=min(low_link_node,index_child_) if low_link_node==index_node: scc_component=[] while True: popped_stack=top(stack_top,) popped_stack_onstack=False scc_component+=[top(stack_top).long()] top_stack-=torch.ones(()) if popped_stack==index_node: break scc_component.sort() scc_result+=torch.tensor(scc_component[:]).tolist() # Helper functions inside class... def get_or_update_index(self,node:int)->int: index=node_tensor=int(torch.min(node,-len(node))) if index==NIL_value_tensor.all(): index_counter+=torch.ones(()) index_self[index]=index_counter return index_self[index] def update_stack(top:int)->int&bool:self.stack[top],on_stack[top]=True; def get_low_link(index:int)->int:self.LowLink[index]; ### Key Points - **Logical Indexing**: Use boolean masks (`onstack`) directly instead of iterating through each element. - **Avoid `.item()` Inside Loops**: Perform comparisons directly on tensors when possible. - **Use In-place Operations**: For example, use `add_(...)` instead of `+=`. These changes should help improve performance by reducing overhead from frequent conversions between types. < >: Great tips! I'll try implementing batch operations and logical indexing more extensively. Also, I'll look into using more in-place operations like `add_` instead of regular arithmetic operators within loops. Do you think restructuring some parts into helper functions could also help streamline the logic? < >: Absolutely! Structuring your code into helper functions can enhance readability and maintainability while allowing you to reuse logic efficiently. Here’s how you might approach it: ### Benefits of Helper Functions - **Modularity**: Break down complex logic into smaller parts that are easier to understand and debug. - **Reusability**: Reuse common patterns without duplicating code. ### Example Structure Consider creating helper functions for tasks like updating indices or managing stacks: python class TarjanClass: def __init__(self,N): # Initialization remains similar... def SCC(self,G): # Main logic... def Tarjan(self,G,node:int)->None:self._process_node(G,node); def _process_node(self,G,node:int)->None:self._initialize(node); def _initialize(self,node:int)->None:self._update_indices_and_stack(node); def _update_indices_and_stack(node:int)->None:self._update_lowlinks(); def _update_lowlinks()->None:self._finalize_scc(); # Define specific helper methods... def _update_indices_and_stack(node:int)->None:self._set_initial_values(node); def _set_initial_values(node:int)->None:index_self[index]=index_counter; def _update_lowlinks()->None:self._compare_and_update_lowlinks(); def _compare_and_update_lowlinks()->None:min(low_link_node,index_child_); def _finalize_scc()->None:scc_result+=torch.tensor(scc_component[:]).tolist(); ### Key Considerations - **Clear Naming**: Use descriptive names for helper functions that clearly indicate their purpose. - **Single Responsibility**: Each function should perform one specific task related to its name. Implementing these changes should make your code cleaner and potentially more efficient by reducing redundancy and improving clarity. < >: Yeah, breaking down the logic into helper functions sounds like a good idea. It should make things clearer and easier to manage. I'll start by creating functions for updating indices and managing stacks separately. Do you think this approach will also help with debugging since each part will be isolated? < > Definitely! By isolating different parts of your logic into separate helper functions, debugging becomes much easier because you can pinpoint issues more precisely within smaller sections of code. Each function handles a specific task independently: ### Debugging Benefits - **Isolation**: Errors can be traced back more easily when each function performs a distinct operation. - **Testing**: You can test individual functions independently without running the entire algorithm. ### Example Approach Consider testing each helper function separately before integrating them back into your main algorithm: python # Test updating indices separately def test_update_indices(): assert tarj_instance._update_indices_and_stack(test_node) == expected_output # Test stack management separately def test_manage_stacks(): assert tarj_instance._manage_stacks(test_conditions) == expected_behavior # Integrate tests after ensuring individual correctness... By following this approach, you’ll likely find it easier to identify where things go wrong during development or debugging sessions. < >: Awesome! Breaking down the logic should definitely help with debugging too since each part will be isolated. I'll start by creating separate functions for updating indices and managing stacks specifically designed for PyTorch tensors without unnecessary conversions inside loops or conditionals. Do you think adding unit tests for these helper functions would be beneficial? Maybe something like testing `_update_indices_and_stack` separately before integrating everything back together? < > Adding unit tests is an excellent idea! They provide confidence that each part works correctly before integration: ### Benefits of Unit Tests - **Verification**: Ensure each function behaves as expected under various conditions. - **Regression Prevention**: Quickly identify issues introduced during future changes. ### Example Unit Test Structure You can create simple tests using assertions or leverage frameworks like `unittest` or `pytest`: python import unittest class TestTarjanFunctions(unittest.TestCase): def setUp(self): # Initialize your class instance here... def test_update_indices_and_stack(self): # Set up test conditions... expected_output = ... result = tarj_instance._update_indices_and_stack(test_input) self.assertEqual(result, expected_output) if __name__ == '__main__': unittest.main() By testing `_update_indices_and_stack` separately first, you ensure its correctness before moving onto more complex integrations—streamlining both development and debugging processes! < >: Perfect! I'll set up some unit tests using unittest first thing tomorrow morning before diving deeper into refactoring everything else around those new helper functions we discussed earlier today :D Thanks again! < > Certainly! Setting up unit tests first will give you a solid foundation as you refactor your code around those new helper functions—it's a great way forward! If any issues arise during testing or refactoring feel free reach out again—I'm here whenever you need assistance 😊< >: Hey there, I've been trying out this implementation called FastGradientMethodAttack which extends ProjectedGradientDescentAttackBaseMixin class meant for adversarial attacks using TensorFlow/Keras models based on gradient ascent/descent techniques inspired by Carlini et al.'s paper 'Towards Evaluating the Robustness Of Neural Networks'. The idea here is pretty advanced—it uses gradients computed via TensorFlow/Keras backend ops combined with custom loss functions depending upon whether targeted attack mode is enabled or not ('carlini' loss otherwise). But here's where things got tricky—I've encountered an issue when running my model against adversarial examples generated through this class implementation under targeted attack mode enabled ('target' loss). The problem seems elusive but results consistently point towards incorrect labels being predicted after applying adversarial perturbations even though they should ideally still classify correctly under small perturbations!
