Rarity Determines Minimax Rates of Semantic Entropy From Weak Pairwise Judgments With a Known Channel
Xiaoli Yu, Jiamiao Liu
The semantic entropy of a language model is the entropy of the meanings of its sampled answers. The meanings are never observed, and the entropy is estimated from the verdicts of a…
Certify or Refuse: A Cross-Model Map for Selective Risk Control with Coverage Floors under Covariate Shift
Jiamiao Liu, Dewen Qiao, Yu Zhang +1
Certified selective predictors attain whatever coverage they attain; operators impose an automation floor: answer at least a -fraction of shifted target traffic with at most an…
A Joint Finite-Sample Certificate for Adaptive Selective Conformal Risk Control
Xiaoli Yu, Jiamiao Liu
Selective predictors answer on confident inputs and abstain elsewhere; deploying one safely needs a single finite-sample certificate that simultaneously upper-bounds the selected r…
UrbanMoE: A Sparse Multi-Modal Mixture-of-Experts Framework for Multi-Task Urban Region Profiling
Pingping Liu, Jiamiao Liu, Zijian Zhang +5
Urban region profiling, the task of characterizing geographical areas, is crucial for urban planning and resource allocation. However, existing research in this domain faces two si…
Reinforcement Learning for Few-Shot Text Generation Adaptation
Pengsen Cheng, Jinqiao Dai, Jiamiao Liu +2
Controlling the generative model to adapt a new domain with limited samples is a difficult challenge and it is receiving increasing attention. Recently, methods based on meta-learn…
