Data Poisoning Attacks on Off-Policy Policy Evaluation Methods

no code implementations6 Apr 2024 Elita Lobo, Harvineet Singh, Marek Petrik, Cynthia Rudin, Himabindu Lakkaraju

Off-policy Evaluation (OPE) methods are a crucial tool for evaluating policies in high-stakes domains such as healthcare, where exploration is often infeasible, unethical, or expensive.

A Brief Tutorial on Sample Size Calculations for Fairness Audits

1 code implementation7 Dec 2023 Harvineet Singh, Fan Xia, Mi-Ok Kim, Romain Pirracchio, Rumi Chunara, Jean Feng

In fairness audits, a standard objective is to detect whether a given algorithm performs substantially differently between subgroups.

Machine Learning for Health symposium 2023 -- Findings track

no code implementations1 Dec 2023 Stefan Hegselmann, Antonio Parziale, Divya Shanmugam, Shengpu Tang, Mercy Nyamewaa Asiedu, Serina Chang, Thomas Hartvigsen, Harvineet Singh

A collection of the accepted Findings papers that were presented at the 3rd Machine Learning for Health symposium (ML4H 2023), which was held on December 10, 2023, in New Orleans, Louisiana, USA.

Designing monitoring strategies for deployed machine learning algorithms: navigating performativity through a causal lens

no code implementations20 Nov 2023 Jean Feng, Adarsh Subbaswamy, Alexej Gossmann, Harvineet Singh, Berkman Sahiner, Mi-Ok Kim, Gene Pennello, Nicholas Petrick, Romain Pirracchio, Fan Xia

When an ML algorithm interacts with its environment, the algorithm can affect the data-generating mechanism and be a major source of bias when evaluating its standalone performance, an issue known as performativity.

"Why did the Model Fail?": Attributing Model Performance Changes to Distribution Shifts

1 code implementation19 Oct 2022 Haoran Zhang, Harvineet Singh, Marzyeh Ghassemi, Shalmali Joshi

In this work, we introduce the problem of attributing performance differences between environments to distribution shifts in the underlying data generating mechanisms.

Towards Robust Off-Policy Evaluation via Human Inputs

no code implementations18 Sep 2022 Harvineet Singh, Shalmali Joshi, Finale Doshi-Velez, Himabindu Lakkaraju

When deployment environments are expected to undergo changes (that is, dataset shifts), it is important for OPE methods to perform robust evaluation of the policies amidst such changes.

Segmenting across places: The need for fair transfer learning with satellite imagery

no code implementations9 Apr 2022 Miao Zhang, Harvineet Singh, Lazarus Chok, Rumi Chunara

This work highlights the need to conduct fairness analysis for satellite imagery segmentation models and motivates the development of methods for fair transfer learning in order not to introduce disparities between places, particularly urban and rural locations.

Learning Under Adversarial and Interventional Shifts

no code implementations29 Mar 2021 Harvineet Singh, Shalmali Joshi, Finale Doshi-Velez, Himabindu Lakkaraju

Most of the existing work focuses on optimizing for either adversarial shifts or interventional shifts.

An RNN-Survival Model to Decide Email Send Times

no code implementations21 Apr 2020 Harvineet Singh, Moumita Sinha, Atanu R. Sinha, Sahil Garg, Neha Banerjee

We posit that emails are likely to be opened sooner when send times are convenient for recipients, while for other send times, emails can get ignored.

Survival Analysis

Fairness Violations and Mitigation under Covariate Shift

no code implementations2 Nov 2019 Harvineet Singh, Rina Singh, Vishwali Mhasawade, Rumi Chunara

We study the problem of learning fair prediction models for unseen test sets distributed differently from the train set.

Modeling Time to Open of Emails with a Latent State for User Engagement Level

no code implementations18 Aug 2019 Moumita Sinha, Vishwa Vinay, Harvineet Singh

In this paper we use a survival analysis framework to predict the time to open an email once it has been received.

Online Diverse Learning to Rank from Partial-Click Feedback

no code implementations1 Nov 2018 Prakhar Gupta, Gaurush Hiranandani, Harvineet Singh, Branislav Kveton, Zheng Wen, Iftikhar Ahamath Burhanuddin

We assume that the user examines the list of recommended items until the user is attracted by an item, which is clicked, and does not examine the rest of the items.
