Time Table and Venue

Deep Learning (DL) is a framework for solving AI problems based on a network of neurons organized in many layers. DL has found heavy use in Natural Language Processing (NLP) too, including problems like machine translation, sentiment and emotion analysis, question answering, information extraction and so on, improving performance on automatic systems by order of magnitude.

The course CS626 (Speech, NLP and the Web) being taught in the first semester in CSE Dept IIT Bombay for last several years creates a strong foundation of NLP covering the whole NLP stack starting from morphology to part of speech tagging, to parsing and discourse and pragmatics. Students of the course which typically number more than 100, acquire a grip on tasks, techniques and linguistics of a plethora of NLP problems.

CS772( Deep Learning for Natural Language Processing) comes as a natural sequel to CS626. Language tasks are examined through the lens of Deep Learning. Foundations and advancements in Deep Learning are taught, integrated with NLP problems. For example, sequence to sequence transformer is covered with application in machine translation. Similarly, various techniques in word embedding are taught with application to text classification, information extraction etc.

CS772 is definitely the need of the hour. While CS626 concentrates on algorithmics and linguistics of NLP, the proposed course will concentrate on Data, Distributions, Neural Models, Non-parametric estimation, Information Coding, Representation and such questions
