This course will examine questions arising from the hypothesis that data lies on a manifold. Special emphasis will be placed on learning Riemannian metrics and studying the Laplace Beltrami Operator. Time permitting, we will also consider the question of generating Lie groups using generators in an efficient way, where efficiency refers to the rate at which approximation error diminishes.
