GaugeVLM: Structuring Spatial Supervision with Measured Geometric Interventions

Hongbo Wang, Zihan Lin, Wenkui Yang وآخرون · 2026

Vision-language models (VLMs) can contradict themselves across views of the same spatial relation and fail to respond when that relation changes. Addressing these failures requires supervision that captures error magnitude and geometric dependencies across observations, both of which remain implicit in training on indi …

TGRL: Temperature-Grouped Reinforcement Learning for Efficient Exploration in LLMs

Zihan Lin, Xiaohan Wang, Jie Cao وآخرون · 2026

Efficient exploration often remains a central bottleneck in reinforcement learning with verifiable rewards (RLVR). Although temperature control and test-time scaling strategies can increase rollout diversity of large language models (LLMs), they either expand the sample budget at rollout time or leave the benefit of ex …
