概要

本論文は、単一センターコンピューティングの限界を克服し、分散学習の重要性が高まるにつれて、異種分散環境での強化学習（RL）ベースの大規模言語モデル（LLM）事後学習の困難を解決するために、非同期RLアーキテクチャであるHeteroRLを提案します。 HeteroRLは、ロールアウトサンプリングとパラメータ学習を分離し、ネットワーク遅延が発生する地理的に分散したノードでも強力なパフォーマンスを提供します。具体的には、遅延によるKL発散が重要度サンプリングの失敗を引き起こす高い分散を引き起こす問題を特定し、それを解決するために、改善されたサンプリングメカニズムを通じて重要度重み分散を減らすGroup Expectation Policy Optimization（GEPO）アルゴリズムを提案します。 GEPOは理論的に指数関数的分散の減少を達成し、実験結果は1800秒の遅延下でも3％未満の性能低下しか見せず、GRPOよりも優れた安定性を維持することを示している。これは、異種ネットワークにおける分散ＲＬの強力な可能性を実証する。
