Adversarial Auto-Augment with Label Preservation: A Representation Learning Principle Guided Approach

1 code implementation2 Nov 2022 Kaiwen Yang, Yanchao Sun, Jiahao Su, Fengxiang He, Xinmei Tian, Furong Huang, Tianyi Zhou, DaCheng Tao

In experiments, we show that our method consistently brings non-trivial improvements to the three aforementioned learning tasks from both efficiency and final performance, either or not combined with strong pre-defined augmentations, e. g., on medical images when domain knowledge is unavailable and the existing augmentation techniques perform poorly.

Class-Disentanglement and Applications in Adversarial Detection and Defense

no code implementations NeurIPS 2021 Kaiwen Yang, Tianyi Zhou, Yonggang Zhang, Xinmei Tian, DaCheng Tao

In this paper, we propose ''class-disentanglement'' that trains a variational autoencoder $G(\cdot)$ to extract this class-dependent information as $x - G(x)$ via a trade-off between reconstructing $x$ by $G(x)$ and classifying $x$ by $D(x-G(x))$, where the former competes with the latter in decomposing $x$ so the latter retains only necessary information for classification in $x-G(x)$.

Identity-Disentangled Adversarial Augmentation for Self-supervised Learning

no code implementations29 Sep 2021 Kaiwen Yang, Tianyi Zhou, Xinmei Tian, DaCheng Tao

We then adversarially perturb $G(x)$ in the VAE's bottleneck space and adds it back to the original $R(x)$ as an augmentation, which is therefore sufficiently challenging for contrastive learning and meanwhile preserves the sample identity intact.

Domain-Class Correlation Decomposition for Generalizable Person Re-Identification

no code implementations29 Jun 2021 Kaiwen Yang, Xinmei Tian

Domain adversarial learning is a promising domain generalization method that aims to remove domain information in the latent representation through adversarial training.
