GraVIS: Grouping Augmented Views from Independent Sources for Dermatology Analysis

no code implementations11 Jan 2023 Hong-Yu Zhou, Chixiang Lu, Liansheng Wang, Yizhou Yu

Self-supervised representation learning has been extremely successful in medical image analysis, as it requires no human annotations to provide transferable representations for downstream tasks.

PCRLv2: A Unified Visual Information Preservation Framework for Self-supervised Pre-training in Medical Image Analysis

1 code implementation2 Jan 2023 Hong-Yu Zhou, Chixiang Lu, Chaoqi Chen, Sibei Yang, Yizhou Yu

Recent advances in self-supervised learning (SSL) in computer vision are primarily comparative, whose goal is to preserve invariant and discriminative semantics in latent representations by comparing siamese image views.

Preservational Learning Improves Self-supervised Medical Image Models by Reconstructing Diverse Contexts

2 code implementations ICCV 2021 Hong-Yu Zhou, Chixiang Lu, Sibei Yang, Xiaoguang Han, Yizhou Yu

From this perspective, we introduce Preservational Learning to reconstruct diverse image contexts in order to preserve more information in learned representations.

ConvNets vs. Transformers: Whose Visual Representations are More Transferable?

no code implementations11 Aug 2021 Hong-Yu Zhou, Chixiang Lu, Sibei Yang, Yizhou Yu

Vision transformers have attracted much attention from computer vision researchers as they are not restricted to the spatial inductive bias of ConvNets.

Generalized Organ Segmentation by Imitating One-shot Reasoning using Anatomical Correlation

no code implementations30 Mar 2021 Hong-Yu Zhou, Hualuo Liu, Shilei Cao, Dong Wei, Chixiang Lu, Yizhou Yu, Kai Ma, Yefeng Zheng

In this paper, we show that such process can be integrated into the one-shot segmentation task which is a very challenging but meaningful topic.
