Learning Variational Neighbor Labels for Test-Time Domain Generalization

no code implementations8 Jul 2023 Sameer Ambekar, Zehao Xiao, Jiayi Shen, XianTong Zhen, Cees G. M. Snoek

We formulate the generalization at test time as a variational inference problem by modeling pseudo labels as distributions to consider the uncertainty during generalization and alleviate the misleading signal of inaccurate pseudo labels.

SKDCGN: Source-free Knowledge Distillation of Counterfactual Generative Networks using cGANs

1 code implementation8 Aug 2022 Sameer Ambekar, Matteo Tafuro, Ankit Ankit, Diego van der Mast, Mark Alence, Christos Athanasiadis

Moreover, as an additional contribution, our paper conducts a thorough study on the composition mechanism of the CGNs, to gain a better understanding of how each mechanism influences the classification accuracy of an invariant classifier.

Unsupervised Domain Adaptation for Semantic Segmentation of NIR Images through Generative Latent Search

2 code implementations ECCV 2020 Prashant Pandey, Aayush Kumar Tyagi, Sameer Ambekar, Prathosh AP

Therefore we cast the skin segmentation problem as that of target-independent Unsupervised Domain Adaptation (UDA) where we use the data from the Red-channel of the visible-range to develop skin segmentation algorithm on NIR images.
