Weijian Deng

Final Year PhD Student

About Me

I am a final year Computer Science PhD student at Australian National University, working with Dr Liang Zheng, Prof Stephen Gould and Dr Yumin Suh.

Research Topic: Model (Out-of-distribution) Generalization.

In my PhD research, the overall objective is Understanding Model Decision under Dynamic Testing Environments. The purpose is two-fold. The first is to provide an unsupervised way to predicate model accuracy under dynamic test scenarios. The second is to better understand the strengths and limitations of MP models. This research will significantly advance machine perception knowledge in dataset representation, model design and decision understanding. Please check our [ TPAMI 2022/CVPR 2021 work] and [ ICML 2021 work]. Here are [some slides] to introduce my research.

Selected Projects

CVPR 2022 Tutorial on "Evaluating Models Beyond the Textbook: Out-of-distribution and Without Labels "

Organizers: Liang Zheng (Australian National University), Ludwig Schmidt (University of Washington), Aditi Raghunathan (Carnegie Mellon University), Weijian Deng (Australian National University)

Our proposed tutorial will give a broad overview of machine learning evaluation with a focus on the two aforementioned issues: evaluation without labels and out-of-distribution. [Tutorial Page]

Visual Domain Adaptation Challenge (VisDA 2020 in conjunction with ECCV 2020)

Organizers: Kate Saenko (Boston University), Liang Zheng (Australian National University), Xingchao Peng (Boston University), Weijian Deng (Australian National University)

This year we focus on domain adaptive instance retrieval, where the source and target domains have completely different classes (instance IDs). The particular task is to retrieve the pedestrian instances of the same ID as the query image. [Chanllenge Page]
