Course Description: This is a graduate-level course on challenges in the alignment and safety of artificial intelligence. We will consider technical questions as well as societal and other impacts of the field.

Prerequisites: We require mathematical maturity and proficiency with proofs, probability, and information theory, along with the foundations of machine learning at the level of an undergraduate course such as Harvard CS 181 or MIT 6.036. On the applied side, students should be comfortable programming in Python and training a basic neural network.
