Diverse Representation Embedding for Lifelong Person Re-Identification

no code implementations24 Mar 2024 Shiben Liu, Huijie Fan, Qiang Wang, Xiai Chen, Zhi Han, Yandong Tang

KU strategy enhances the adaptive learning ability of learner models for new information under the adjustment model prior, and KP strategy preserves old knowledge operated by representation-level alignment and logit-level supervision in limited old task datasets while guaranteeing the adaptive learning information capacity of the LReID model.

Depth Selection for Deep ReLU Nets in Feature Extraction and Generalization

no code implementations1 Apr 2020 Zhi Han, Siquan Yu, Shao-Bo Lin, Ding-Xuan Zhou

One of the most important challenge of deep learning is to figure out relations between a feature and the depth of deep neural networks (deep nets for short) to reflect the necessity of depth.

Video Primal Sketch: A Unified Middle-Level Representation for Video

no code implementations10 Feb 2015 Zhi Han, Zongben Xu, Song-Chun Zhu

This paper presents a middle-level video representation named Video Primal Sketch (VPS), which integrates two regimes of models: i) sparse coding model using static or moving primitives to explicitly represent moving corners, lines, feature points, etc., ii) FRAME /MRF model reproducing feature statistics extracted from input video to implicitly represent textured motion, such as water and fire.
