Rescuing referral failures during automated diagnosis of domain-shifted medical images

no code implementations28 Nov 2023 Anuj Srivastava, Karm Patel, Pradeep Shenoy, Devarajan Sridharan

Here, we address a fundamental challenge with selective classification during automated diagnosis with domain-shifted medical images.

Shaken, and Stirred: Long-Range Dependencies Enable Robust Outlier Detection with PixelCNN++

1 code implementation29 Aug 2022 Barath Mohan Umapathi, Kushal Chauhan, Pradeep Shenoy, Devarajan Sridharan

We also show that our solutions work well with other types of generative models (generative flows and variational autoencoders) and that their efficacy is governed by each model's reliance on local dependencies.

Robust outlier detection by de-biasing VAE likelihoods

1 code implementation CVPR 2022 Kushal Chauhan, Barath Mohan U, Pradeep Shenoy, Manish Gupta, Devarajan Sridharan

Likelihoods computed by deep generative models (DGMs) are a candidate metric for outlier detection with unlabeled data.

Mapping distinct timescales of functional interactions among brain networks

no code implementations NeurIPS 2017 Mali Sundaresan, Arshed Nabeel, Devarajan Sridharan

First, we show, with simulated fMRI data, that instantaneous and lag-based GC identify distinct timescales and complementary patterns of functional connectivity.
