CS772: Deep Learning for Natural Language Processing (Spring, 2025)
Department of Computer Science and Engineering
Indian Institute of Technology Bombay
Time Table and Venue:
- Slot: 14

- Tuesday: 5:30 PM to 6:55 PM
- Friday: 5:30 PM to 6:55 PM
Motivation:
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 orders of magnitude.
The course CS626 (Speech, NLP, and the Web) being taught in the first semester in the CSE Department at IIT Bombay for the last several years creates a strong foundation in 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 transformers are covered with applications in machine translation. Similarly, various techniques in word embedding are taught with applications to text classification, information extraction, etc.
