Semantics Meets Temporal Correspondence: Self-supervised Object-centric Learning in Videos

1 code implementation ICCV 2023 Rui Qian, Shuangrui Ding, Xian Liu, Dahua Lin

In the second stage, for each semantics, we randomly sample slots from the corresponding Gaussian distribution and perform masked feature aggregation within the semantic area to exploit temporal correspondence patterns for instance identification.

Prune Spatio-temporal Tokens by Semantic-aware Temporal Accumulation

1 code implementation ICCV 2023 Shuangrui Ding, Peisen Zhao, Xiaopeng Zhang, Rui Qian, Hongkai Xiong, Qi Tian

Based on the STA score, we are able to progressively prune the tokens without introducing any additional parameters or requiring further re-training.

Dual Contrastive Learning for Spatio-temporal Representation

no code implementations12 Jul 2022 Shuangrui Ding, Rui Qian, Hongkai Xiong

In this way, the static scene and the dynamic motion are simultaneously encoded into the compact RGB representation.

Masked Autoencoders are Robust Data Augmentors

1 code implementation10 Jun 2022 Haohang Xu, Shuangrui Ding, Xiaopeng Zhang, Hongkai Xiong, Qi Tian

Specifically, MRA consistently enhances the performance on supervised, semi-supervised as well as few-shot classification.

Motion-aware Contrastive Video Representation Learning via Foreground-background Merging

1 code implementation CVPR 2022 Shuangrui Ding, Maomao Li, Tianyu Yang, Rui Qian, Haohang Xu, Qingyi Chen, Jue Wang, Hongkai Xiong

To alleviate such bias, we propose \textbf{F}oreground-b\textbf{a}ckground \textbf{Me}rging (FAME) to deliberately compose the moving foreground region of the selected video onto the static background of others.

Towards More Practical Adversarial Attacks on Graph Neural Networks

2 code implementations NeurIPS 2020 Jiaqi Ma, Shuangrui Ding, Qiaozhu Mei

Our theoretical and empirical analyses suggest that there is a discrepancy between the loss and mis-classification rate, as the latter presents a diminishing-return pattern when the number of attacked nodes increases.
