This project is designed to give you experience doing empirical AI research, and will build upon our previous natural language processing and machine learning lectures and homework assignments. It will also give you exposure to a cutting edge research area, and experience in building a real AI system. You will be given a corpus of pre-classified email messages, and will be asked to first extract some features from them, then use machine learning techniques on the extracted features to perform several kinds of automatic classification. Your result will be some email filters that work more or less well.
