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. ## Co-authors here 12 of 16 co-authors with a page, the most papers together first. - [Ganqu Cui](https://md.research.elamur.ai/free/en/authors/ganqu-cui/) ×2 - [Lifan Yuan](https://md.research.elamur.ai/free/en/authors/lifan-yuan/) ×2 - [Weize Chen](https://md.research.elamur.ai/free/en/authors/weize-chen/) ×2 - [Yuchen Fan](https://md.research.elamur.ai/free/en/authors/yuchen-fan/) ×2 - [Yuchen Zhang](https://md.research.elamur.ai/free/en/authors/yuchen-zhang/) ×2 - [Bingxiang He](https://md.research.elamur.ai/free/en/authors/bingxiang-he/) - [Hanbin Wang](https://md.research.elamur.ai/free/en/authors/hanbin-wang/) - [Hao Peng](https://md.research.elamur.ai/free/en/authors/hao-peng/) - [Haozhan Li](https://md.research.elamur.ai/free/en/authors/haozhan-li/) - [Huayu Chen](https://md.research.elamur.ai/free/en/authors/huayu-chen/) - [Tianyu Yu](https://md.research.elamur.ai/free/en/authors/tianyu-yu/) - [Wendi Li](https://md.research.elamur.ai/free/en/authors/wendi-li/) ## Cited by Papers of our library cite their works 249 times (of the 149,439 papers whose bibliographies we read); [88 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/jiacheng-chen/cited-by/).
