MeTA: Multi-source Test Time Adaptation

no code implementations4 Jan 2024 Sk Miraj Ahmed, Fahim Faisal Niloy, Dripta S. Raychaudhuri, Samet Oymak, Amit K. Roy-Chowdhury

Test time adaptation is the process of adapting, in an unsupervised manner, a pre-trained source model to each incoming batch of the test data (i. e., without requiring a substantial portion of the test data to be available, as in traditional domain adaptation) and without access to the source data.

STRIDE: Single-video based Temporally Continuous Occlusion Robust 3D Pose Estimation

no code implementations24 Dec 2023 Rohit Lal, Saketh Bachu, Yash Garg, Arindam Dutta, Calvin-Khang Ta, Dripta S. Raychaudhuri, Hannah Dela Cruz, M. Salman Asif, Amit K. Roy-Chowdhury

This challenge arises because these models struggle to generalize beyond their training datasets, and the variety of occlusions is hard to capture in the training data.

Effective Restoration of Source Knowledge in Continual Test Time Adaptation

no code implementations8 Nov 2023 Fahim Faisal Niloy, Sk Miraj Ahmed, Dripta S. Raychaudhuri, Samet Oymak, Amit K. Roy-Chowdhury

By restoring the knowledge from the source, it effectively corrects the negative consequences arising from the gradual deterioration of model parameters caused by ongoing shifts in the domain.

Prior-guided Source-free Domain Adaptation for Human Pose Estimation

no code implementations ICCV 2023 Dripta S. Raychaudhuri, Calvin-Khang Ta, Arindam Dutta, Rohit Lal, Amit K. Roy-Chowdhury

To address this limitation, we focus on the task of source-free domain adaptation for pose estimation, where a source model must adapt to a new target domain using only unlabeled target data.

SUMMIT: Source-Free Adaptation of Uni-Modal Models to Multi-Modal Targets

1 code implementation ICCV 2023 Cody Simons, Dripta S. Raychaudhuri, Sk Miraj Ahmed, Suya You, Konstantinos Karydis, Amit K. Roy-Chowdhury

In this work, we relax both of these assumptions by addressing the problem of adapting a set of models trained independently on uni-modal data to a target domain consisting of unlabeled multi-modal data, without having access to the original source dataset.

Controllable Dynamic Multi-Task Architectures

no code implementations CVPR 2022 Dripta S. Raychaudhuri, Yumin Suh, Samuel Schulter, Xiang Yu, Masoud Faraki, Amit K. Roy-Chowdhury, Manmohan Chandraker

In contrast to the existing dynamic multi-task approaches that adjust only the weights within a fixed architecture, our approach affords the flexibility to dynamically control the total computational cost and match the user-preferred task importance better.

Reconstruction guided Meta-learning for Few Shot Open Set Recognition

no code implementations31 Jul 2021 Sayak Nag, Dripta S. Raychaudhuri, Sujoy Paul, Amit K. Roy-Chowdhury

However, it is a critical task in many applications like environmental monitoring, where the number of labeled examples for each class is limited.

Cross-domain Imitation from Observations

no code implementations20 May 2021 Dripta S. Raychaudhuri, Sujoy Paul, Jeroen van Baar, Amit K. Roy-Chowdhury

Once this correspondence is found, we can directly transfer the demonstrations on one domain to the other and use it for imitation.

Unsupervised Multi-source Domain Adaptation Without Access to Source Data

1 code implementation CVPR 2021 Sk Miraj Ahmed, Dripta S. Raychaudhuri, Sujoy Paul, Samet Oymak, Amit K. Roy-Chowdhury

A recent line of work addressed this problem and proposed an algorithm that transfers knowledge to the unlabeled target domain from a single source model without requiring access to the source data.

Exploiting Temporal Coherence for Self-Supervised One-shot Video Re-identification

no code implementations ECCV 2020 Dripta S. Raychaudhuri, Amit K. Roy-Chowdhury

While supervised techniques in re-identification are extremely effective, the need for large amounts of annotations makes them impractical for large camera networks.

Channel masking for multivariate time series shapelets

no code implementations2 Nov 2017 Dripta S. Raychaudhuri, Josif Grabocka, Lars Schmidt-Thieme

Time series shapelets are discriminative sub-sequences and their similarity to time series can be used for time series classification.
