Neural Scaling Laws of Transformer Operator Network

This work develops a theoretical framework for characterizing the approximation and generalization errors of transformer-based operator learning, and derives a universal approximation error of transformer-based operator learning for H\"older-regular operators".

Domain-Adapted Diffusion Models for Conditional Independence Testing

Domain-Adapted Diffusion (DA-Diff), a multi-source domain adaptation framework for conditional diffusion models based on weighted empirical risk minimization over both target and source domains, is proposed andExperiments demonstrate that DA-Diff improved conditional generation quality compared with transfer-learning d...

Sharp training-conditional coverage for conformal prediction under covariate shift

Weighted split conformal prediction reweights calibration scores by the likelihood ratio between the test and training covariate distributions and guarantees marginal coverage under covariate shift. We study its coverage conditional on the calibration data. An elementary argument, based on a single concentration inequa...

The Statistical Benefits of Multiple Responses for Learning from Demonstrations

It is found that multiple responses provide a qualitatively stronger benefit in this setting of generative systems, and is shown that a greedy multiplicative-weights learner achieving the upper bounds without any assumption on demonstrator quality is possible.

Offline Policy Evaluation via Mixed Bellman Residuals and Adaptive Critic Representations

A convex combination of one-step and two-step residuals with a fixed mixing weight is considered to provide a natural bias--variance trade-off between approximation error under a restricted value-function class and the increased variance arising from multi-step importance weighting.

Can Tabular Foundation Models Amortize Statistical Inference?

TabCon is developed, an amortized inference system built on a tabular foundation model that produces confidence intervals for new datasets through a simple forward pass, and offers considerably greater computational efficiency than the classical bootstrap procedure.

Byzantine-Robust Federated RAG via Aligned Calibration and Fixed-Membership Conformal Prediction

Retrieval-augmented generation (RAG) lets language models answer questions more accurately by consulting relevant documents. Many valuable collections, such as medical records, cannot be pooled because of privacy rules. Federated RAG leaves each collection with its owner, or node, which scores candidate answers from it...

Sliced Orlicz-Wasserstein

We propose sliced Orlicz-Wasserstein (SOW) distance which is a generalization of sliced Wasserstein (SW) distance. SOW replaces the $L^p$ norm in SW with a Luxemburg norm cost induced by an Orlicz function $\phi$. First, we prove that SOW distance is a metric on the space of measures with finite Orlicz norm, and show t...

Domain Adaptation with Target Information via Doubly-Anchored Distributionally Robust Optimization

A doubly-anchored DRO framework whose ambiguity set is the intersection of $\phi$-divergence balls centered at the source law and a source-completed target reference law, the latter pairing the target covariate law with the source conditional law is introduced.
