Interactive Concept Bottleneck Models

1 code implementation14 Dec 2022 Kushal Chauhan, Rishabh Tiwari, Jan Freyberg, Pradeep Shenoy, Krishnamurthy Dvijotham

Concept bottleneck models (CBMs) are interpretable neural networks that first predict labels for human-interpretable concepts relevant to the prediction task, and then predict the final label based on the concept label predictions.

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.

Outlier Detection

Matching options to tasks using Option-Indexed Hierarchical Reinforcement Learning

no code implementations12 Jun 2022 Kushal Chauhan, Soumya Chatterjee, Akash Reddy, Balaraman Ravindran, Pradeep Shenoy

The options framework in Hierarchical Reinforcement Learning breaks down overall goals into a combination of options or simpler tasks and associated policies, allowing for abstraction in the action space.

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.

Improving Segmentation for Technical Support Problems

1 code implementation ACL 2020 Kushal Chauhan, Abhirut Gupta

We formulate the problem as a sequence labelling task, and study the performance of state of the art approaches.
