Should the Boundary Term Be Learned in Reflected Diffusion? Conormal Trace and Reflection Masking

Ziyue Wang, Takafumi Kanamori

We study score learning for reflected diffusion on bounded domains. Reflection keeps trajectories feasible but does not ensure that the learned score satisfies the boundary behavio…

Fast boundary-aware spatial intensity estimation on complex domains

Takumi Nakagawa, Kōsaku Takanashi, Kenichiro McAlinn +1

Spatial intensity maps are routinely used to summarize point patterns on geographically constrained regions, such as islands, coastlines, watersheds, ecological reserves, and admin…

Generalized Distribution-Free Semi-Supervised Learning with Risk Rewrite

Yushi Hirose, Hiroo Irobe, Takafumi Kanamori

Typical semi-supervised learning (SSL) methods rely on distributional assumptions, and their performance degrades when these are violated. While PNU learning, a risk rewriting meth…

Distributional Spectral Diagnostics for Localizing Grokking Transitions

Ziyue Wang, Yufeng Ying, Takafumi Kanamori

In grokking, a model first fits the training data while test accuracy remains low, and only later begins to generalize. We ask whether this transition can be localized from observe…

TULiP: Test-time Uncertainty Estimation via Linearization and Weight Perturbation

Yuhui Zhang, Dongshen Wu, Yuichiro Wada +1

A reliable uncertainty estimation method is the foundation of many modern out-of-distribution (OOD) detectors, which are critical for safe deployments of deep learning models in th…

Statistical learnability of smooth boundaries via pairwise binary classification with deep ReLU networks

Hiroki Waida, Takafumi Kanamori

The topic of nonparametric estimation of smooth boundaries is extensively studied in the conventional setting where pairs of single covariate and response variable are observed. Ho…
