Betting Tips and Strategies

Finding Value Bets

To maximize your betting potential, consider these strategies:

  • Analyze recent form and head-to-head statistics to identify undervalued teams.
  • Favor bets on over/under goals when teams have contrasting styles (e.g., defensive vs. attacking).
  • Leverage live betting opportunities during matches to capitalize on dynamic changes in gameplay.

Risk Management

Betting should always be approached with caution. Implement risk management techniques such as:

  • Betting within your means - Set limits on how much you're willing to wager.
  • Diversifying bets across different markets to spread risk.
  • Maintaining discipline by sticking to your betting strategy regardless of short-term outcomes.

<|repo_name|>kendalll/thesis<|file_sep|>/analysis.tex chapter{Analysis} In this chapter we describe our evaluation framework for the new model. We begin by describing how we adapt existing datasets for our purposes. We then describe how we measure performance, and finally present results from evaluating our model using these datasets. section{Datasets} In order to evaluate our model, we use two existing datasets: one containing sentences from medical textbooks, and one containing sentences from medical case reports. We describe each dataset below. subsection{Medical Textbooks} Our first dataset consists of sentences from medical textbooks. We use the MIMIC-III Clinical Text Database~cite{Johnson2016MIMIC}, which contains discharge summaries from intensive care unit patients, as well as clinical notes written by physicians. The database also contains text from various other sources, including textbooks~cite{Johnson2016Textbooks}. For our purposes we use only the textbook data. The textbook data contains sentences from three textbooks: textit{Harrison's Principles of Internal Medicine}, textit{Oxford Handbook of Clinical Medicine}, and textit{The Merck Manual Professional Version}. Each sentence in this dataset has been annotated with a binary label indicating whether or not it contains at least one disease mention. We use these sentences as our positive examples, along with their annotations. We create negative examples by selecting random sentences from the discharge summaries in MIMIC-III that do not contain disease mentions. As mentioned above, we discard discharge summaries containing disease mentions because they are too similar to our positive examples. In order to balance our dataset, we randomly select equal numbers of positive and negative examples. subsection{Case Reports} Our second dataset consists of sentences from medical case reports. Case reports are articles describing unusual cases, and often contain descriptions of patients' symptoms and details about how they were diagnosed. They also frequently mention multiple diseases that are relevant to understanding each patient's condition. To construct this dataset we used PubMed~cite{weng2008pubmed}, a database containing over $26$ million articles published in medical journals. To find relevant articles we performed a search using the query ``case report'' with no date restriction. This query returned $1$ million articles, of which we randomly selected $10$ thousand articles. For each article we extracted all sentences containing at least one disease mention, using MetaMap~cite{aronson2010metamap} to identify disease mentions. We used MetaMap because it is able to map mentions of diseases that are referred to by different names (e.g., myocardial infarction & heart attack) to a common concept identifier~cite{arons1998metamap}. Using this approach, we extracted $100$ thousand sentences containing disease mentions. As before, we use these sentences as our positive examples, along with their annotations. We create negative examples by selecting random sentences from the same articles that do not contain disease mentions. As before, we discard articles containing disease mentions because they are too similar to our positive examples. In order to balance our dataset, we randomly select equal numbers of positive and negative examples. section{Evaluation Metrics} To evaluate our model we use two standard metrics: area under curve (AUC) score~cite{Hanley1982Area} and mean average precision (MAP)~cite{Voorhees1999TREC}. AUC score measures the quality of binary classifiers by calculating the area under their receiver operating characteristic curves~cite{Hanley1982Area}. MAP measures the quality of ranked lists by averaging precision scores across all queries~cite{Voorhees1999TREC}. For MAP score we treat each sentence in our test set as a separate query. We first calculate precision scores at all ranks for each query, then average those scores across all queries. A higher MAP score indicates that more relevant sentences are ranked higher. For AUC score we treat each sentence in our test set as a separate example, and calculate its predicted probability using our model. We then plot true positive rate versus false positive rate at all possible thresholds and calculate area under that curve. section{Results} In this section we present results obtained using our datasets described above. In Section ref{ssec:setup} we describe how we split our data into training, validation, and test sets. In Section ref{ssec:base} we compare performance between our model and existing models when trained only on textual features. In Section ref{ssec:full} we compare performance between our model and existing models when trained on both textual features and structured features derived from clinical ontologies. subsection{Setup} label{ssec:setup} For both datasets described above, we split data into training, validation, and test sets using an $80$%, $10$%, $10$% split respectively. We train all models using training set data only; we tune hyperparameters using validation set data only; and finally evaluate performance using test set data only. All models were implemented using Python version $3$.footnote{url{https://www.python.org/}} We used Keras~cite{chollet2015keras} version $2$.1.footnote{url{https://keras.io/}} to implement neural network architectures described below. We used scikit-learn version $0$.19.footnote{url{https://scikit-learn.org/stable/}} for implementing other machine learning models described below. For hyperparameter tuning we used scikit-learn's texttt{GridSearchCV} function to perform grid search over multiple values for each hyperparameter; this function automatically performs cross-validation over all combinations of hyperparameter values during training, so that best hyperparameter values can be selected based on validation set performance. % Neural network architectures For all neural network architectures described below, we use character-level embeddings with dimensionality $50$;
