Bingchen Zhao

I am a Ph.D student at the University of Edinburgh, supervised by Dr Oisin Mac Aodha.
I am interested in Concept/Category Discovery, Self-Supervised Learning, and Interpretable AI.
Please feel free to drop me an email if you are interested in what I do and looking for possible collaborations.

Preprints

	Vision Learners Meet Web Image-Text Pairs Bingchen Zhao, Quan Cui, Hao Wu, Osamu Yoshie, Cheng Yang arXiv / Website Preprint TL;DR: We present a visual representation pre-training method for scalable web image-text data and it achieves state-of-the-art performance on various tasks with promising scaling behavior.
	A Simple Parametric Classification Baseline for Generalized Category Discovery Xin Wen, Bingchen Zhao, Xiaojuan Qi arXiv / Code Preprint TL;DR: A simple yet effective baseline for Generalized Category Discovery is proposed based on several observations from our investigation, we were able to surpass previous SOTA by a large margin.

Conference Papers

	XCon: Learning with Experts for Fine-grained Category Discovery Yixin Fei, Zhongkai Zhao, Siwei Yang, Bingchen Zhao arXiv / Slides / Code BMVC 2022 Oral (34/770=4.4%) TL;DR: Learning to do category discovery within a fine-grained dataset is challenging, we present a method that learn to do that by partition the dataset into k sub-groups, and show improved performance on several fine-grained datasets.
	Self-Supervised Visual Representation Learning with Semantic Grouping Xin Wen, Bingchen Zhao, Anlin Zheng, Xiangyu Zhang, Xiaojuan Qi arXiv / Website / Code NeurIPS 2022 TL;DR: Our model can do scene decomposition and representation learning at the same time and shows strong generalization ability pretrained on scene-centric data.
	OOD-CV: A Benchmark for Robustness to Out-of-Distribution Shifts of Individual Nuisances in Natural Images Bingchen Zhao, Shaozuo Yu, Wufei Ma, Mingxin Yu, Shenxiao Mei, Angtian Wang, Ju He, Alan Yuille, Adam Kortylewski. arXiv / Website / Download / Slides ECCV 2022 Oral (158/5803=2.7%) TL;DR: We collected a dataset where we have the control over the individual OOD attribute in the test examples.
	Discriminability-Transferability Trade-Off: An Information-Theoretic Perspective Quan Cui, Bingchen Zhao, Zhao-Min Chen, Borui Zhao, Renjie Song, Jiajun Liang, Boyan Zhou, Osamu Yoshie. arXiv / Code / Slides ECCV 2022 TL;DR: We study the transferability and the discriminability of deep representations and found a trade-off between these two properties.
	Novel Visual Category Discovery with Dual Ranking Statistics and Mutual Knowledge Distillation Bingchen Zhao, Kai Han. arXiv / Code / Slides NeurIPS 2021 TL;DR: We extend novel category discovery to discover fine-grained classes by leverging information from image parts.
	Improving Contrastive Learning by Visualizing Feature Transformation Rui Zhu, Bingchen Zhao, Jingen Liu, Zhenglong Sun, Chang Wen Chen. arXiv / Code / Slides ICCV 2021 Oral (210/6236=3.4%) TL;DR: We explore the training dynamics of self-supervised contrastive learning, and proposed two simple method for improving the performance of the model.
	Temporal Context Aggregation for Video Retrieval with Contrastive Learning Jie Shao, Xin Wen, Bingchen Zhao, Xiangyang Xue. arXiv / Code / Slides WACV 2021 TL;DR: Video retrieval methods can be improved by modeling long-range temporal information with transformer and contrastive learning.

Workshop Papers

One Venue, Two Conferences: The Separation of Chinese and American Citation Networks
Bingchen Zhao*, Yuling Gu*, Jessica Zosa Forde, Naomi Saphra
arXiv
NeurIPS 2022 AI Cultures Workshop
TL;DR: At NeurIPS, American and Chinese institutions cite papers from each other's regions substantially less than they cite endogamously. We build a citation graph to quantify this divide, compare it to European connectivity, and discuss the causes and consequences of the separation.

Distilling Visual Priors from Self-Supervised Learning
Bingchen Zhao, Xin Wen
arXiv / Code / Slides
ECCV 2020 VIPriors Workshop
TL;DR: Learning a model self-supervisedly and then do self-distillation helps in the data-deficient domain.
