This directory includes three functions to run neural networks, random forests, K nearest neighbors, and Gaussian mixture models (GMMs). 
All three functions use the same inputData.mat which contains 6 variables: feat_vec_train, feat_vec_devtest, feat_vec_evltest,
labels_train, labels_devtest, and labels_evltest. These pertain to feature vectors for training, validation, and evaluation sets whose 
rows represent the # of samples and columns represent # of features.
