Research
I'm interested in Machine Learning, Bayesian Models, and Meta-Learning. Much of my research is to address challenging problems in multi-task learning.

Association Graph Learning for Multi-Task Classification with Category Shifts
Jiayi Shen,
Zehao Xiao,
Xiantong Zhen,
Cees Snoek,
Marcel Worring
NeurIPS, 2022
paper /
code
We propose a new MTL setting which suffers from category shifts from training to test data.

Haochen Wang,
Jiayi Shen,
Yongtuo Liu,
Yan Gao (Xiaohongshu Inc.),
Efstratios Gavves
CVPR, 2022
paper /
code
We propose a Neighbor Transformer Network, or NFormer, which explicitly models interactions across all input images.

Variational Multi-Task Learning with Gumbel-Softmax Priors
Jiayi Shen,
Xiantong Zhen,
Marcel Worring,
Ling Shao
NeurIPS, 2021
paper /
code
We propose variational multi-task learning (VMTL), a general probabilistic inference framework for learning multiple related tasks.

A Bit More Bayesian: Domain-Invariant Learning with Uncertainty
Zehao Xiao,
Jiayi Shen,
Xiantong Zhen,
Ling Shao,
Cees Snoek
ICML, 2021
paper /
code
To better explore domain invariant learning, we introduce weight uncertainty to the model by leveraging variational Bayesian inference.
