A Study of Policy Gradient on a Class of Exactly Solvable Models
Gavin McCracken, Colin Daniels, Rosie Zhao +3
Policy gradient methods are extensively used in reinforcement learning as a way to optimize expected return. In this paper, we explore the evolution of the policy parameters, for a…
The Horton-Strahler Number of Conditioned Galton-Watson Trees
Anna M. Brandenberger, Luc Devroye, Tommy Reddad
The Horton-Strahler number of a tree is a measure of its branching complexity; it is also known in the literature as the register function. We show that for critical Galton-Watson…
Root estimation in Galton-Watson trees
Anna M. Brandenberger, Luc Devroye, Marcel K. Goh
Given only the free-tree structure of a tree, the root estimation problem asks if one can guess which of the free tree's nodes is the root of the original tree. We determine the ma…
