DeepCompress: A Dual Reward Strategy for Dynamically Exploring and Compressing Reasoning Chains

Tian Liang, Wenxiang Jiao, Zhiwei He +3

Large Reasoning Models (LRMs) have demonstrated impressive capabilities but suffer from cognitive inefficiencies like "overthinking" simple problems and "underthinking" complex one…

Locas: Your Models are Principled Initializers of Locally-Supported Parametric Memories

Sidi Lu, Zhenwen Liang, Dongyang Ma +3

In this paper, we aim to bridge test-time-training with a new type of parametric memory that can be flexibly offloaded from or merged into model parameters. We present Locas, a Loc…

DeepTheorem: Advancing LLM Reasoning for Theorem Proving Through Natural Language and Reinforcement Learning

Ziyin Zhang, Jiahao Xu, Zhiwei He +10

Theorem proving serves as a major testbed for evaluating complex reasoning abilities in large language models (LLMs). However, traditional automated theorem proving (ATP) approache…

DeepMath-103K: A Large-Scale, Challenging, Decontaminated, and Verifiable Mathematical Dataset for Advancing Reasoning

Zhiwei He, Tian Liang, Jiahao Xu +12

Reinforcement learning (RL) with large language models shows promise in complex reasoning. However, its progress is hindered by the lack of large-scale training data that is suffic…

Trust, But Verify: A Self-Verification Approach to Reinforcement Learning with Verifiable Rewards

Xiaoyuan Liu, Tian Liang, Zhiwei He +6

Large Language Models (LLMs) show great promise in complex reasoning, with Reinforcement Learning with Verifiable Rewards (RLVR) being a key enhancement strategy. However, a preval…
