Neural networks: Theory and Applications

Spring 2018 schedule:  COS495

Organization of synaptic connectivity as the basis of neural computation and learning. Perceptrons, convolutional nets, and recurrent nets. Backpropagation and Hebbian learning. Engineering applications including computer vision and natural language processing.

Requirements

  • Two 80 minute lectures and one precept per week.
  • Grades (A-F) will be based on class participation (5%), problem sets (25%), midterm (30%), and final exam (40%).
  • Participation includes speaking up in lecture and precept.
  • Participation also includes activity on Piazza—ideally asking good questions, giving good answers, and upvoting others’ contributions.

Prerequisites

  • Familiarity with linear algebra.
  • Basics of optimization and probability theory.
  • Knowledge of Julia or Python (or willingness to learn).

Lectures

Prof. Sebastian Seung will lecture twice a week.
