86-375/675 (15-387) Computational Perception

Carnegie Mellon University

Fall 2016

Course Description

The perceptual capabilities of even the simplest biological organisms are far beyond what we can achieve with machines. Whether you look at sensitivity, robustness, or sheer perceptual power, perception in biology just works, and works in complex, ever changing environments, and can pick up the most subtle sensory patterns. Is it the neural hardware? Does biology solve fundamentally different problems? What can we learn from biological systems and human perception?

In this course, we will first study the biological and psychological data of biological perceptual systems in depth, and then apply computational thinking to investigate the principles and mechanisms underlying natural perception. The course will focus primarily on visual perception this year. You will learn how to reason scientifically and computationally about problems and issues in perception, how to extract the essential computational properties of those abstract ideas, and finally how to convert these into explicit mathematical models and computational algorithms. The course is targeted to neuroscience and psychology students who are interested in learning computational thinking, and computer science and engineering students who are interested in learning more about the neural basis of perception. Prerequisites: First year college calculus, some linear algebra, probability theory and programming experience are desirable.
