Deciphering Spatial Cellular Organization through RNA-Anchored Multi-Omics Deconvolution

Spatial technologies that jointly profile RNA and additional molecular layers provide a comprehensive view of tissue organization, yet their limited resolution results in measurements that reflect mixtures of multiple cell types. While RNA-based deconvolution methods are well established, incorporating co-profiled non-...

Inferential Evaluation of Surrogate-Derived Models under Covariate Shift

Cross-fitted estimators that transport information from the two labeled sources through source-specific density ratios are proposed that establish asymptotically linear inference for TPR and FPR, consistency and pointwise inference for the ROC curve, and asymptotically normal inference for AUC.

Personalizing Large Language Model Agents with Small Policy Models

This work forms personalization of a frozen agent as online learning of a per-user execution policy from scalar feedback observed only for the executed action, and proposes FABLE (Factorized Adaptive Bandit Layer for Execution), a lightweight policy layer outside a potentially black-box host agent.
