Beyond First-Order Tweedie: Solving Inverse Problems using Latent Diffusion

no code implementations1 Dec 2023 Litu Rout, Yujia Chen, Abhishek Kumar, Constantine Caramanis, Sanjay Shakkottai, Wen-Sheng Chu

To our best knowledge, this is the first work to offer an efficient second-order approximation in solving inverse problems using latent diffusion and editing real-world images with corruptions.

Distributionally Robust Post-hoc Classifiers under Prior Shifts

1 code implementation16 Sep 2023 Jiaheng Wei, Harikrishna Narasimhan, Ehsan Amid, Wen-Sheng Chu, Yang Liu, Abhishek Kumar

We investigate the problem of training models that are robust to shifts caused by changes in the distribution of class-priors or group-priors.

Rethinking Domain Generalization for Face Anti-spoofing: Separability and Alignment

1 code implementation CVPR 2023 Yiyou Sun, Yaojie Liu, Xiaoming Liu, Yixuan Li, Wen-Sheng Chu

This work studies the generalization issue of face anti-spoofing (FAS) models on domain gaps, such as image resolution, blurriness and sensor variations.

Adaptive Transformers for Robust Few-shot Cross-domain Face Anti-spoofing

no code implementations23 Mar 2022 Hsin-Ping Huang, Deqing Sun, Yaojie Liu, Wen-Sheng Chu, Taihong Xiao, Jinwei Yuan, Hartwig Adam, Ming-Hsuan Yang

While recent face anti-spoofing methods perform well under the intra-domain setups, an effective approach needs to account for much larger appearance variations of images acquired in complex scenes with different sensors for robust performance.
