FeedTrans: Enhance Machine Translation via Feedback

Large reasoning models (LRMs) have shown exceptional performance in complex tasks such as mathematics and coding. In the field of machine translation (MT), reinforcement learning (RL) has been utilized to enhance the quality of translations. However, traditional RL approaches rely heavily on the base model’s inherent...

SWE-MILE: Asynchronous Potential-Induced Milestone Credit Assignment for Long-Horizon Software Engineering Agents

Long-horizon software engineering (SWE) agents trained with reinforcement learning with verifiable rewards (RLVR) typically receive only terminal outcome supervision, making it difficult to distinguish productive actions from redundant exploration or functional regressions. We propose SWE-MILE, an asynchronous potentia...

Self-Improving Large Language Models via Progressive Experience Evolution

Large language models (LLMs) capable of self-improvement require not only effective policy optimization, but also a principled mechanism for transforming transient interaction experience into persistent model capabilities. Existing self-improvement paradigms remain fragmented: test-time methods can explicitly extract e...

Not Just Reason, Not Just Scan: Reinforcement Learning for Proactive Scientific Error Verification over Academic Paper

This work presents VERA-RL, a reinforcement-learning formulation for scientific error detection over academic papers, and constructs VERA-13K, a 12,900-sample dataset organized into 4,300 matched chains, covering 6 scientific-error categories across the research workflow and broad natural-science domains.

EvoBrowseComp: Benchmarking Search Agents on Evolving Knowledge

EvoBrowseComp is introduced, an evolving benchmark of 400 English and 400 Chinese contamination-free complex questions synthesized via live-web traversal that establishes a scalable paradigm for auto-updatable, high-difficulty benchmarking that keeps pace with both evolving world knowledge and advancing agent capabilit...

PolyWorkBench: Benchmarking Multilingual Long-Horizon LLM Agents

This work introduces PolyWorkBench, a benchmark for evaluating LLM agents on multilingual long-horizon workplace workflows, and proposes a hybrid framework that combines structural grading, executable verification, and LLM-based semantic assessment to enable comprehensive evaluation.

PolyWorkBench: Benchmarking LLM Agents for Cross-Lingual Long-Horizon Workflows

Benchmark evaluations reveal that agent performance varies substantially across languages and drops sharply on the harder cross-lingual tasks, and analysis shows that multilingual execution exposes systematic failure modes across planning, tool interaction, and decision-making in long-horizon agents.
