Entropy is not Enough for Test-Time Adaptation: From the Perspective of Disentangled Factors

ICLR 2024spotlight

Test-time adaptation (TTA) fine-tunes pre-trained deep neural networks for unseen test data. The primary challenge of TTA is limited access to the entire test dataset during online updates, causing error accumulation. To mitigate it, TTA methods have utilized the model output's entropy as a confiden…

SF(DA)$^2$: Source-free Domain Adaptation Through the Lens of Data Augmentation

ICLR 2024poster

In the face of the deep learning model's vulnerability to domain shift, source-free domain adaptation (SFDA) methods have been proposed to adapt models to new, unseen target domains without requiring access to source domain data. Although the potential benefits of applying data augmentation to SFDA…

Stein Latent Optimization for Generative Adversarial Networks

ICLR 2022poster

Generative adversarial networks (GANs) with clustered latent spaces can perform conditional generation in a completely unsupervised manner. In the real world, the salient attributes of unlabeled data can be imbalanced. However, most of existing unsupervised conditional GANs cannot cluster attributes…
