CLDA: Contrastive Learning for Semi-Supervised Domain Adaptation

no code implementations NeurIPS 2021 Ankit Singh

In this paper, we propose a simple Contrastive Learning framework for semi-supervised Domain Adaptation (CLDA) that attempts to bridge the intra-domain gap between the labeled and unlabeled target distributions and inter-domain gap between source and unlabeled target distribution in SSDA.

Semi-Supervised Action Recognition with Temporal Contrastive Learning

1 code implementation CVPR 2021 Ankit Singh, Omprakash Chakraborty, Ashutosh Varshney, Rameswar Panda, Rogerio Feris, Kate Saenko, Abir Das

We approach this problem by learning a two-pathway temporal contrastive model using unlabeled videos at two different speeds leveraging the fact that changing video speed does not change an action.

Emergence of cooperatively reorganizing cluster and super-Arrhenius dynamics of fragile supercooled liquids

no code implementations18 Nov 2020 Ankit Singh, Sarika Maitra Bhattacharyya, Yashwant Singh

It is shown that the value of {\psi}(T ) is equal to 1 for T > T a indicating that the underlying microscopic mechanism of relaxation is dominated by the entropy driven processes while for T < T a , {\psi}(T ) decreases on cooling indicating the emergence of the energy driven processes.

Mitigating Dataset Imbalance via Joint Generation and Classification

1 code implementation12 Aug 2020 Aadarsh Sahoo, Ankit Singh, Rameswar Panda, Rogerio Feris, Abir Das

In this work we address these questions from the perspective of dataset imbalance resulting out of severe under-representation of annotated training data for certain classes and its effect on both deep classification and generation methods.
