Are Emily and Greg Still More Employable than Lakisha and Jamal? Investigating Algorithmic Hiring Bias in the Era of ChatGPT

no code implementations8 Oct 2023 Akshaj Kumar Veldanda, Fabian Grob, Shailja Thakur, Hammond Pearce, Benjamin Tan, Ramesh Karri, Siddharth Garg

We replicate this experiment on state-of-art LLMs (GPT-3. 5, Bard, Claude and Llama) to evaluate bias (or lack thereof) on gender, race, maternity status, pregnancy status, and political affiliation.

Application of BadNets in Spam Filters

no code implementations18 Jul 2023 Swagnik Roychoudhury, Akshaj Kumar Veldanda

Our results show that the backdoor attacks can be effectively used to identify vulnerabilities in spam filters and suggest the need for ongoing monitoring and improvement in this area.

Fairness via In-Processing in the Over-parameterized Regime: A Cautionary Tale

no code implementations29 Jun 2022 Akshaj Kumar Veldanda, Ivan Brugere, Jiahao Chen, Sanghamitra Dutta, Alan Mishler, Siddharth Garg

We further show that MinDiff optimization is very sensitive to choice of batch size in the under-parameterized regime.

NNoculation: Catching BadNets in the Wild

1 code implementation19 Feb 2020 Akshaj Kumar Veldanda, Kang Liu, Benjamin Tan, Prashanth Krishnamurthy, Farshad Khorrami, Ramesh Karri, Brendan Dolan-Gavitt, Siddharth Garg

This paper proposes a novel two-stage defense (NNoculation) against backdoored neural networks (BadNets) that, repairs a BadNet both pre-deployment and online in response to backdoored test inputs encountered in the field.
