In this paper, we study the problem of binary sentiment classification on a set of polar movie reviews. There are many models which have achieved state of the art performance, but one has to deal with the problem of tuning a large number of hyper-parameters. With the addition of the deep forest model as proposed by Zhi-Hua and Ji Feng, the number of hyperparameters to be tuned is less and the architecture is still able to perform well. The goal of this paper is to use Word2Vec, FastText and Doc2Vec for creating word vector representation of the reviews which are then trained on a deep forest model. In order to further enhance the performance, the trained model is further trained on a different set of classifiers and as a result, a significant improvement in performance was noticed.
