Goal Agnostic Planning using Maximum Likelihood Paths in Hypergraph World Models

no code implementations18 Oct 2021 Christopher Robinson

In this paper, we present a hypergraph--based machine learning algorithm, a datastructure--driven maintenance method, and a planning algorithm based on a probabilistic application of Dijkstra's algorithm.
