Quasi-Monte Carlo Initialization for Meta-Reinforcement Learning

A new study from arXiv finds that quasi-Monte Carlo weight initialization improves training convergence in meta-reinforcement learning compared to modern orthogonal defaults (SB3) when extrapolated to similar unseen continuous control environments. The paper, submitted on 21 Jul 2026, shows that QMC meta-priors outperform orthogonal initialization on similar tasks, but orthogonal orientation remains globally superior for dissimilar tasks.

Abstract:This paper explores the efficacy of quasi-Monte Carlo (QMC) weight initialization for meta-reinforcement learning within modern benchmark environments. Various sampling methods are used to bound a population-based search and aggregate an optimal prior from a baseline set of tasks. The QMC meta-priors show improvements in training convergence compared to modern orthogonal (SB3) defaults when extrapolated to similar unseen continuous control environments. In dissimilar tasks, the orthogonal orientation was globally superior for an unbiased search.
