Fixed-Gaussian Spectral Algorithms: Minimax Optimal Rates for Misspecified Learning and Transfer

arXiv:2501. 10870v2 Announce Type: replace-cross Abstract: The principal objective of this work is twofold within nonparametric regression settings: (1) to establish the minimax optimal convergence rates for fixed-bandwidth Gaussian kernel spectral algorithms when the true regression function resides in a Sobolev space, and (2) to apply Gaussian spectral algorithms for achieving robust and adaptive transfer learning under concept shift.

Sparse POD Mode Selection and Manifold Dimensionality Reduction with Neural Networks

arXiv:2605. 27756v2 Announce Type: replace-cross Abstract: Linear dimensionality reduction methods such as proper orthogonal decomposition (POD) make high-dimensional data amenable to analysis by identifying the principal components, or modes, that capture the most variance, or energy, in the data and constructing a low-dimensional representation in the subspace they span.

Robust Broad Learning System with Wave Loss for Classification under Data Uncertainty

The paper introduces Wave-BLS, a robust Broad Learning System that replaces the traditional squared error loss with an asymmetric, bounded, and smooth wave loss function. This change allows controlled penalization of large errors and eliminates the need for matrix inversion by using a Nesterov accelerated gradient scheme. Experiments on 30 UCI datasets show that Wave-BLS consistently outperforms classical BLS and other robust variants, with statistical tests confirming the significance of the improvements and demonstrating greater resilience to noise and outliers.
