Efficient Approximation to Analytic and LpL^p functions by Height-Augmented ReLU Networks

This paper introduces a three-dimensional height-augmented ReLU network architecture that achieves significantly more efficient exponential approximation rates for analytic functions and provides the first quantitative, non-asymptotic high-order approximation for general LpL^p functions, thereby advancing the theoretical foundation for designing parameter-efficient neural networks.

Co-Diffusion: An Affinity-Aware Two-Stage Latent Diffusion Framework for Generalizable Drug-Target Affinity Prediction

Co-Diffusion is a novel two-stage latent diffusion framework that enhances generalizable drug-target affinity prediction by aligning embeddings in an affinity-steered manifold and employing modality-specific diffusion as a regularizer, thereby achieving superior zero-shot performance on unseen molecular scaffolds and protein families compared to state-of-the-art methods.

On noncentral Wishart mixtures of noncentral Wisharts and their use for testing random effects in factorial design models

This paper demonstrates that a noncentral Wishart mixture of noncentral Wishart distributions with identical degrees of freedom remains a noncentral Wishart distribution, a result used to derive the finite-sample distribution for testing random effects in two-factor and general factorial design models with multivariate normal data.

Intrinsic Geometry-Based Angular Covariance: A Novel Framework for Nonparametric Changepoint Detection in Meteorological Data

This paper introduces a novel nonparametric framework for detecting changepoints in the mean direction of toroidal and spherical meteorological data by leveraging intrinsic geometry to define a curved dispersion matrix and Mahalanobis distance, establishing the statistical properties of the proposed tests and validating them on wind-wave directions and cyclonic storm paths.

A Restricted Latent Class Model with Polytomous Attributes and Respondent-Level Covariates

This paper introduces an exploratory restricted latent class model that accommodates polytomous responses, ordinal multi-attribute states with correlated attributes via a multivariate probit specification, and respondent-level covariates, demonstrating its effectiveness in recovering parameters and revealing complex latent structures in depression diagnosis beyond traditional single-factor approaches.
