Objectives:

To understand the fundamentals of research areas, where Neuroscience, Machine learning and Engineering interact such as Vision, Audition, Natural Language and Reinforcement learning.

This interdisciplinary course will consist of lectures and hands on tutorials and is based on the premise that a two-way interchange between neuroscience and machine learning/AI will be mutually productive. The Lectures will be conducted by the faculty of IIT Madras, interacting with scientists at the Center for Computational Brain Research as well as world renowned international experts visiting the center during the course. The course focuses on four main areas of robust interactions between engineering and neuroscience (Vision, Speech/Audition, Natural Language and Reinforcement Learning) and also includes related topics (classical Machine Learning, Hardware and Statistical Physics).

    • Object recognition and detection,

    • Depth estimation,

    • Video based activity recognition.

Module 2: Audition
