Similarity Is Not Logic: Factored Inference for Dual-Encoder Vision-Language Models

Sultan Alshehri, Zhantao Yang, Han Zhang +1

Dual-encoder vision-language models (VLMs) expose a similarity interface that enables zero-shot retrieval but fails compositional constraints: queries like "umbrella and no person"…

PACE: Policy-Native Adaptive Decision Timing for Long-Horizon Reasoning

Chen Li, Zhantao Yang, Fangyi Chen +3

Long-horizon reasoning requires deciding not only what actions to take, but how many to execute open-loop before replanning. This number, the execution depth, balances replanning c…
