Each classifier is implemented with the following specifications:

Naïve Bayes (NB): Multinomial NB with additive smoothing constant 1

Logistic Regression (LR): Linear LR with L2 regularization constant 1 and limited-memory BFGS optimization

Support Vector Machine (SVM): Linear SVM with L2 regularization constant 1 and logistic loss function

Random Forests (RF): Averaging probabilistic predictions of 10 randomized decision trees

Gradient Boosted Trees (GBT): Tree boosting with learning rate 1 and logistic loss function Along with traditional machine learning approaches, we investigate neural network based models to evaluate their efficacy within a larger dataset. In particular, we explore Convolutional Neural Networks (CNN), Recurrent Neural Networks (RNN), and their variant models.
