From Concentration to Differentiation and Back: Routing Effective Rank in MoE Reasoning Cohorts
Kang Chen, Sihan Zhao, Yixin Cao +1
Test-time scaling produces cohorts of reasoning rollouts, yet there is no standard label-free account of how their internal computation reorganizes as inference unfolds. We introdu…
Beyond the Trace: Coupling an Interpretable Reasoning-State Readout to Native MoE Routing
Kang Chen, Sihan Zhao, Yixin Cao +1
What a reasoning model writes is only a partial record of the process that produces it. We introduce a two-level internal readout for mixture-of-experts reasoning. We first distill…
Disagree to Explore, Agree to Commit: Routing-Guided Test-Time Scaling for Software Agents
Kang Chen, Junjie Nian, Yixin Cao +1
Software-engineering agents solve repository-level tasks through long, stochastic tool-use trajectories, and repeated attempts often find fixes missed by one run. Test-time scaling…
SliceGraph: Mapping Process Isomers in Multi-Run Chain-of-Thought Reasoning
Kang Chen, Junjie Nian, Yixin Cao +1
Multi-run chain-of-thought reasoning is usually collapsed to final-answer aggregates, which discard howsampled trajectories share, split, and rejoin through intermediate computatio…
ARM: Role-Conditioned Neuron Transplantation for Training-Free Generalist LLM Agent Merging
Zhuoka Feng, Kang Chen, Sihan Zhao +7
Interactive large language model agents have advanced rapidly, but most remain specialized to a single environment and fail to adapt robustly to other environments. Model merging o…
