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

1 code implementation16 Mar 2024 Uiwon Hwang, Jonghyun Lee, Juhyeon Shin, Sungroh Yoon

We construct an augmentation graph in the feature space of the pretrained model using the neighbor relationships between target features and propose spectral neighborhood clustering to identify partitions in the prediction space.

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

no code implementations12 Mar 2024 Jonghyun Lee, Dahuin Jung, Saehyung Lee, Junsung Park, Juhyeon Shin, Uiwon Hwang, Sungroh Yoon

To mitigate it, TTA methods have utilized the model output's entropy as a confidence metric that aims to determine which samples have a lower likelihood of causing error.

Gradient Alignment with Prototype Feature for Fully Test-time Adaptation

no code implementations14 Feb 2024 Juhyeon Shin, Jonghyun Lee, Saehyung Lee, MinJun Park, Dongjun Lee, Uiwon Hwang, Sungroh Yoon

In context of Test-time Adaptation(TTA), we propose a regularizer, dubbed Gradient Alignment with Prototype feature (GAP), which alleviates the inappropriate guidance from entropy minimization loss from misclassified pseudo label.
