Boosting Continuous Control with Consistency Policy

1 code implementation10 Oct 2023 Yuhui Chen, Haoran Li, Dongbin Zhao

By establishing a mapping from the reverse diffusion trajectories to the desired policy, we simultaneously address the issues of time efficiency and inaccurate guidance when updating diffusion model-based policy with the learned Q-function.

Single Domain Dynamic Generalization for Iris Presentation Attack Detection

no code implementations22 May 2023 Yachun Li, Jingjing Wang, Yuhui Chen, Di Xie, ShiLiang Pu

To tackle the above issues, we propose a Single Domain Dynamic Generalization (SDDG) framework, which simultaneously exploits domain-invariant and domain-specific features on a per-sample basis and learns to generalize to various unseen domains with numerous natural images.

Few-shot One-class Domain Adaptation Based on Frequency for Iris Presentation Attack Detection

no code implementations1 Apr 2022 Yachun Li, Ying Lian, Jingjing Wang, Yuhui Chen, Chunmao Wang, ShiLiang Pu

We thus define a new domain adaptation setting called Few-shot One-class Domain Adaptation (FODA), where adaptation only relies on a limited number of target bonafide samples.
