Nonadiabatic polaron dynamics from machine-learned hopping trajectories

Daniela Mangano, Luca Leoni, Zhongfei Xu +2

The formation and motion of small polarons are ubiquitous in energy materials and influence photoinduced processes. Polaron transport is governed by thermally activated lattice dyn…

Dr. Free: You Don't Need Difficulty Rewards for Self-Evolving Search Agents

Zhipeng Qian, Zihan Liang, Yufei Ma +10

A central limitation of current data-free self-evolution methods for training search agents is their reliance on difficulty-based proposer rewards. These methods reward a proposer…

Annotations as Rollouts: Efficient and Scalable Reinforcement Learning for Video MLLMs

Yunheng Li, Guohong Mu, Hao Li +4

Multimodal large language models (MLLMs) have become a prevailing paradigm for unified video perception. However, post-training on large multi-task datasets remains challenging, as…

Plan Before Search: Search Agents Need Plan

Zhipeng Qian, Zihan Liang, Yufei Ma +7

Training large language models as retrieval-augmented reasoning agents typically combines reinforcement learning with an SFT cold start distilled from a stronger model. However, th…

Degradation Frequency Curve: An Explicit Frequency-Quantified Representation for All-in-One Image Restoration

Xinghua Huang, Zhixiong Yang, Chen Wu +6

A fundamental difficulty in all-in-one blind image restoration is that degradation is usually treated as an implicit factor hidden in degraded-to-clean mapping, rather than as an e…

Easy Samples Are All You Need: Self-Evolving LLMs via Data-Efficient Reinforcement Learning

Zhiyin Yu, Bo Zhang, Qibin Hou +3

Previous LLMs-based RL studies typically follow either supervised learning with high annotation costs, or unsupervised paradigms using voting or entropy-based rewards. However, the…
