Quantifying Feature Contributions to Overall Disparity Using Information Theory

no code implementations16 Jun 2022 Sanghamitra Dutta, Praveen Venkatesh, Pulkit Grover

If we have access to the decision-making model, one potential approach (inspired from intervention-based approaches in explainability literature) is to vary each individual feature (while keeping the others fixed) and use the resulting change in disparity to quantify its contribution.

Can Information Flows Suggest Targets for Interventions in Neural Circuits?

1 code implementation NeurIPS 2021 Praveen Venkatesh, Sanghamitra Dutta, Neil Mehta, Pulkit Grover

Motivated by neuroscientific and clinical applications, we empirically examine whether observational measures of information flow can suggest interventions.

Fairness Under Feature Exemptions: Counterfactual and Observational Measures

no code implementations14 Jun 2020 Sanghamitra Dutta, Praveen Venkatesh, Piotr Mardziel, Anupam Datta, Pulkit Grover

While quantifying disparity is essential, sometimes the needs of an occupation may require the use of certain features that are critical in a way that any disparity that can be explained by them might need to be exempted.

CodeNet: Training Large Scale Neural Networks in Presence of Soft-Errors

no code implementations4 Mar 2019 Sanghamitra Dutta, Ziqian Bai, Tze Meng Low, Pulkit Grover

This work proposes the first strategy to make distributed training of neural networks resilient to computing errors, a problem that has remained unsolved despite being first posed in 1956 by von Neumann.

A Unified Coded Deep Neural Network Training Strategy Based on Generalized PolyDot Codes for Matrix Multiplication

no code implementations27 Nov 2018 Sanghamitra Dutta, Ziqian Bai, Haewon Jeong, Tze Meng Low, Pulkit Grover

First, we propose a novel coded matrix multiplication technique called Generalized PolyDot codes that advances on existing methods for coded matrix multiplication under storage and communication constraints.

On the Optimal Recovery Threshold of Coded Matrix Multiplication

3 code implementations31 Jan 2018 Sanghamitra Dutta, Mohammad Fahim, Farzin Haddadpour, Haewon Jeong, Viveck Cadambe, Pulkit Grover

We provide novel coded computation strategies for distributed matrix-matrix products that outperform the recent "Polynomial code" constructions in recovery threshold, i. e., the required number of successful workers.

Coded Distributed Computing for Inverse Problems

no code implementations NeurIPS 2017 Yaoqing Yang, Pulkit Grover, Soummya Kar

Our experiments for personalized PageRank performed on real systems and real social networks show that this ratio can be as large as $10^4$.

Short-Dot: Computing Large Linear Transforms Distributedly Using Coded Short Dot Products

no code implementations NeurIPS 2016 Sanghamitra Dutta, Viveck Cadambe, Pulkit Grover

The fusion node can exploit this redundancy by completing the computation using outputs from only a subset of the processors, ignoring the stragglers.

no code implementations4 Apr 2015 Karthik Ganesan, Pulkit Grover, Jan Rabaey, Andrea Goldsmith

We analyze scaling behavior under two VLSI complexity models of decoding.
