In this work, we propose Self-Fix Step-DPO (SFS-DPO), a reinforcement learning based, two-stage framework for step-level self-verification and self-correction. The first stage strengthens step-level reasoning via step-level preference optimization, while the second stage explicitly trains models to self-verify and self-correct. We further introduce a teacher-assisted variant, SFS-DPO-R, which incorporates explanatory rationales for error verification to provide stronger corrective signals. Comprehensive in-domain and out-of-domain evaluations across multiple LLMs demonstrate that SFS-DPO and SFS-DPO-R consistently outperform prior step-level training baselines. Our analysis further reveals improvements in self-correction frequency and effectiveness, highlighting the importance of strengthening step-level reasoning for robust performance.", "url": "https://wpnews.pro/news/reinforcing-step-level-reasoning-for-effective-self-correction-in-llms", "canonical_source": "https://arxiv.org/abs/2608.11573", "published_at": "2026-08-13 04:00:00+00:00", "updated_at": "2026-08-13 04:12:00.921164+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "large-language-models", "ai-research"], "entities": ["Self-Fix Step-DPO", "SFS-DPO", "SFS-DPO-R"], "alternates": {"html": "https://wpnews.pro/news/reinforcing-step-level-reasoning-for-effective-self-correction-in-llms", "markdown": "https://wpnews.pro/news/reinforcing-step-level-reasoning-for-effective-self-correction-in-llms.md", "text": "https://wpnews.pro/news/reinforcing-step-level-reasoning-for-effective-self-correction-in-llms.txt", "jsonld": "https://wpnews.pro/news/reinforcing-step-level-reasoning-for-effective-self-correction-in-llms.jsonld"}}
