ALIVE: Warnings Before Exclusion in Budgeted Multi-Source Learning

Xiyang Zhang, Hongzhi Wang, Yuanhe Tian

A routing decision can be revised at the next transaction, but a latched source exclusion persists across later decisions. We ask what evidence should authorize these unequal-persi…

Nearly Optimal Bayesian Inference for Structural Missingness

Chen Liang, Donghua Yang, Yutong Zhao +9

Structural missingness breaks 'just impute and train': values can be undefined by causal or logical constraints, and the mask may depend on observed variables, unobserved variables…
