New research explores reinforcement learning generalization across domains

A new arXiv paper explores the transfer of learning between different domains in reinforcement learning (RL) for language models. The study, titled "Where and What to Reward? Understanding Generalization Between Verifiable and Open-Ended Domains in Reinforcement Learning," investigates how models trained on verifiable rewards (RLVR) and those trained on human feedback for open-ended conversations (RLHF) perform when their training data is varied. Researchers found that RLHF on open-ended prompts significantly boosts conversational abilities and also improves reasoning and coding tasks, while RLVR primarily enhances reasoning but shows limited gains in open-ended conversation. AI

IMPACT This research suggests that training language models on open-ended conversational data can lead to broader improvements across various tasks, potentially influencing future training methodologies for AI.

    Where and What to Reward? Understanding Generalization Between Verifiable and Open-Ended Domains in Reinforcement Learning

    arXiv:2605.15464v2 Announce Type: replace-cross Abstract: Reinforcement learning with verifiable rewards (RLVR) is widely used to improve the reasoning capability of language models, since model-generated answers can be easily verified by a rule-based verifier. In contrast, reinf…
