Natural-Language-Processing-with-Classification-and-Vector-Spaces

Classification and Vector Spaces in NLP This is the first course of the Natural Language Processing Specialization.

Week 1: Logistic Regression for Sentiment Analysis of Tweets

• Use a simple method to classify positive or negative sentiment in tweets

Week 2: Naïve Bayes for Sentiment Analysis of Tweets

• Use a more advanced model for sentiment analysis

Week 3: Vector Space Models

• Use vector space models to discover relationships between words and use principal component analysis (PCA) to reduce the dimensionality of the vector space and visualize those relationships

Week 4: Word Embeddings and Locality Sensitive Hashing for Machine Translation

• Write a simple English-to-French translation algorithm using pre-computed word embeddings and locality sensitive hashing to relate words via approximate k-nearest neighbors search
