Weijian Deng

I am a Research Fellow at the Australian National University, working with Prof Stephen Gould. My current research focuses are Neural Radiance Fields and Out-of-Distribution Generalization.
Previously, I was a PhD student at the Australian National University, where I worked on model generalization prediction, working with Prof Stephen Gould, Dr Yumin Suh, and Dr Liang Zheng.

PhD Research Topic: Model (Out-of-Distribution) Generalization Prediction

My research aspiration is to build robust and reliable machine perception models that exhibit exceptional generalization capabilities across various distribution shifts. Machine perception algorithms are commonly devised and assessed based on oversimplified assumptions that frequently fail to hold true in real-world scenarios. My research is focused on developing innovative unsupervised generalization prediction.
I am interested in exploring an important but largely unexplored question: Are Labels Always Necessary for Model Evaluation? The primary focus lies in the accurate prediction of model generalization across diverse testing environments without relying on human annotations. The significance of this investigation lies in its potential to identify and diagnose potential failure cases, while also providing valuable guidance for future model training endeavors. Here are [some slides] to introduce my research.
