New Soft Q(λ) method enhances off-policy reinforcement learning

Researchers have introduced Soft $Q(\lambda)$, a novel multi-step off-policy method for entropy-regularized reinforcement learning. This framework extends existing soft Q-learning techniques by enabling efficient credit assignment under arbitrary behavior policies. The proposed method utilizes a new Soft Tree Backup operator and eligibility traces, offering a model-free approach for learning entropy-regularized value functions that can be applied in future empirical studies.

    Soft $Q(\lambda)$: A multi-step off-policy method for entropy regularised reinforcement learning using eligibility traces

    arXiv:2604.13780v2 Announce Type: replace-cross Abstract: Soft Q-learning has emerged as a versatile model-free method for entropy-regularised reinforcement learning, optimising for returns augmented with a penalty on the divergence from a reference policy. Despite its success, t…
