New 'Excursion Policies' Enhance Off-Policy Reinforcement Learning

Researchers have introduced "excursion policies" as a novel approach to off-policy reinforcement learning. This method involves an agent following a target policy for a set number of steps before returning to a behavior policy. The study provides theoretical underpinnings for these policies through dynamic programming results and develops corresponding temporal-difference algorithms. Excursion policies demonstrate a trade-off between efficiency and stability, performing comparably to mixture policies on continuous control benchmarks. AI

IMPACT Introduces a new theoretical framework and algorithms for improving the efficiency and stability of off-policy reinforcement learning.

    Off-policy Learning with Excursion Policies

    arXiv:2611.13275v1 Announce Type: cross Abstract: Off-policy reinforcement learning (RL) tries to learn the value of a target policy while data comes from a different behavior policy. This often requires trading off bias for variance or stability. One way to trade these off is to…
