Pooling Image Datasets With Multiple Covariate Shift and Imbalance

no code implementations5 Mar 2024 Sotirios Panagiotis Chytas, Vishnu Suresh Lokhande, Peiran Li, Vikas Singh

Further, we discuss how this style of formulation offers a unified perspective on at least 5+ distinct problem settings, from self-supervised learning to matching problems in 3D reconstruction.

Equivariance Allows Handling Multiple Nuisance Variables When Analyzing Pooled Neuroimaging Datasets

1 code implementation CVPR 2022 Vishnu Suresh Lokhande, Rudrasis Chakraborty, Sathya N. Ravi, Vikas Singh

Pooling multiple neuroimaging datasets across institutions often enables improvements in statistical power when evaluating associations (e. g., between risk factors and disease outcomes) that may otherwise be too weak to detect.

Graph Reparameterizations for Enabling 1000+ Monte Carlo Iterations in Bayesian Deep Neural Networks

no code implementations19 Feb 2022 Jurijs Nazarovs, Ronak R. Mehta, Vishnu Suresh Lokhande, Vikas Singh

This is directly related to the structure of the computation graph, which can grow linearly as a function of the number of MC samples needed.

Towards Group Robustness in the presence of Partial Group Labels

no code implementations10 Jan 2022 Vishnu Suresh Lokhande, Kihyuk Sohn, Jinsung Yoon, Madeleine Udell, Chen-Yu Lee, Tomas Pfister

Such a requirement is impractical in situations where the data labeling efforts for minority or rare groups are significantly laborious or where the individuals comprising the dataset choose to conceal sensitive information.

Invariant Learning with Partial Group Labels

no code implementations29 Sep 2021 Vishnu Suresh Lokhande, Kihyuk Sohn, Jinsung Yoon, Madeleine Udell, Chen-Yu Lee, Tomas Pfister

Such a requirement is impractical in situations where the data labelling efforts for minority or rare groups is significantly laborious or where the individuals comprising the dataset choose to conceal sensitive information.

Learning Invariant Representations using Inverse Contrastive Loss

1 code implementation16 Feb 2021 Aditya Kumar Akash, Vishnu Suresh Lokhande, Sathya N. Ravi, Vikas Singh

Learning invariant representations is a critical first step in a number of machine learning tasks.

FairALM: Augmented Lagrangian Method for Training Fair Models with Little Regret

1 code implementation ECCV 2020 Vishnu Suresh Lokhande, Aditya Kumar Akash, Sathya N. Ravi, Vikas Singh

We provide a detailed technical analysis and present experiments demonstrating that various fairness measures from the literature can be reliably imposed on a number of training tasks in vision in a manner that is interpretable.

Active Learning with Importance Sampling

no code implementations10 Oct 2019 Muni Sreenivas Pydi, Vishnu Suresh Lokhande

We consider an active learning setting where the algorithm has access to a large pool of unlabeled data and a small pool of labeled data.
