• Generated feature vectors for processing 50,000 IMDB reviews and 900,000 tweets while achieving an accuracy of ~85% and ~64% respectively

• The first one was Doc2Vec technique where document vectors are learned via artificial neural networks which captures the context of the words while reducing the size of the data.
