Data Imputation by Pursuing Better Classification: A Supervised Kernel-Based Method

no code implementations13 May 2024 Ruikai Yang, Fan He, Mingzhen He, Kaijie Wang, Xiaolin Huang

In this paper, we propose a new framework that effectively leverages supervision information to complete missing data in a manner conducive to classification.

Decentralized Kernel Ridge Regression Based on Data-dependent Random Feature

no code implementations13 May 2024 Ruikai Yang, Fan He, Mingzhen He, Jie Yang, Xiaolin Huang

Random feature (RF) has been widely used for node consistency in decentralized kernel ridge regression (KRR).

Revisiting Random Weight Perturbation for Efficiently Improving Generalization

1 code implementation30 Mar 2024 Tao Li, Qinghua Tao, Weihao Yan, Zehao Lei, Yingwen Wu, Kun Fang, Mingzhen He, Xiaolin Huang

Improving the generalization ability of modern deep neural networks (DNNs) is a fundamental challenge in machine learning.

Enhancing Kernel Flexibility via Learning Asymmetric Locally-Adaptive Kernels

1 code implementation8 Oct 2023 Fan He, Mingzhen He, Lei Shi, Xiaolin Huang, Johan A. K. Suykens

To enhance kernel flexibility, this paper introduces the concept of Locally-Adaptive-Bandwidths (LAB) as trainable parameters to enhance the Radial Basis Function (RBF) kernel, giving rise to the LAB RBF kernel.
