Don't Forget What I did?: Assessing Client Contributions in Federated Learning

no code implementations11 Mar 2024 Bishwamittra Ghosh, Debabrota Basu, Fu Huazhu, Wang Yuan, Renuga Kanagavelu, Jiang Jin Peng, Liu Yong, Goh Siow Mong Rick, Wei Qingsong

Additionally, to assess client contribution under limited computational budget, we propose a scheduling procedure that considers a two-sided fairness criteria to perform expensive Shapley value computation only in a subset of training epochs.

Efficient Learning of Interpretable Classification Rules

no code implementations14 May 2022 Bishwamittra Ghosh, Dmitry Malioutov, Kuldeep S. Meel

The interpretability of rule-based classifiers is in general related to the size of the rules, where smaller rules are considered more interpretable.

Algorithmic Fairness Verification with Graphical Models

1 code implementation20 Sep 2021 Bishwamittra Ghosh, Debabrota Basu, Kuldeep S. Meel

In recent years, machine learning (ML) algorithms have been deployed in safety-critical and high-stake decision-making, where the fairness of algorithms is of paramount importance.

Probably Approximately Correct Explanations of Machine Learning Models via Syntax-Guided Synthesis

no code implementations18 Sep 2020 Daniel Neider, Bishwamittra Ghosh

We propose a novel approach to understanding the decision making of complex machine learning models (e. g., deep neural networks) using a combination of probably approximately correct learning (PAC) and a logic inference methodology called syntax-guided synthesis (SyGuS).

Justicia: A Stochastic SAT Approach to Formally Verify Fairness

1 code implementation14 Sep 2020 Bishwamittra Ghosh, Debabrota Basu, Kuldeep S. Meel

We instantiate Justicia on multiple classification and bias mitigation algorithms, and datasets to verify different fairness metrics, such as disparate impact, statistical parity, and equalized odds.

A Formal Language Approach to Explaining RNNs

no code implementations12 Jun 2020 Bishwamittra Ghosh, Daniel Neider

This paper presents LEXR, a framework for explaining the decision making of recurrent neural networks (RNNs) using a formal description language called Linear Temporal Logic (LTL).

IMLI: An Incremental Framework for MaxSAT-Based Learning of Interpretable Classification Rules

no code implementations7 Jan 2020 Bishwamittra Ghosh, Kuldeep S. Meel

While MLIC was shown to achieve accuracy similar to that of other state of the art black-box classifiers while generating small interpretable CNF formulas, the runtime performance of MLIC is significantly lagging and renders approach unusable in practice.
