Functional sufficient dimension reduction through information maximization with application to classification

no code implementations18 May 2023 Xinyu Li, Jianjun Xu, Wenquan Cui, Haoyang Cheng

Considering the case where the response variable is a categorical variable and the predictor is a random function, two novel functional sufficient dimensional reduction (FSDR) methods are proposed based on mutual information and square loss mutual information.

Contrastive Continuity on Augmentation Stability Rehearsal for Continual Self-Supervised Learning

no code implementations ICCV 2023 Haoyang Cheng, Haitao Wen, Xiaoliang Zhang, Heqian Qiu, Lanxiao Wang, Hongliang Li

In order to address catastrophic forgetting without overfitting on the rehearsal samples, we propose Augmentation Stability Rehearsal (ASR) in this paper, which selects the most representative and discriminative samples by estimating the augmentation stability for rehearsal.

An RKHS-Based Semiparametric Approach to Nonlinear Sufficient Dimension Reduction

no code implementations5 Jan 2021 Wenquan Cui, Haoyang Cheng

By casting the nonlinear dimensional reduction problem in a generalized semiparametric framework, we calculate the orthogonal complement space of generalized nuisance tangent space to derive the estimating equation.
