Without explicit regularization, policy entropy falls to almost zero within the first training steps. The model becomes overconfident, stops exploring and its validation accuracy stalls. 2. **[Free Process Rewards without Process Labels](https://md.research.elamur.ai/free/en/papers/yuan-2024-free-process-rewards-process-labels/)** *(2024 · 58 citations)* Process reward models (PRMs) score each step of a reasoning chain and often beat outcome reward models (ORMs), but they need step-level labels. ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1.
