To Pool or Not To Pool: Analyzing the Regularizing Effects of Group-Fair Training on Shared Models

no code implementations29 Feb 2024 Cyrus Cousins, I. Elizabeth Kumar, Suresh Venkatasubramanian

In fair machine learning, one source of performance disparities between groups is over-fitting to groups with relatively few training samples.

Measuring and mitigating voting access disparities: a study of race and polling locations in Florida and North Carolina

no code implementations30 May 2022 Mohsen Abbasi, Suresh Venkatasubramanian, Sorelle A. Friedler, Kristian Lum, Calvin Barrett

In this paper, we quantify access to polling locations, developing a methodology for the calibrated measurement of racial disparities in polling location "load" and distance to polling locations.

Repairing Regressors for Fair Binary Classification at Any Decision Threshold

no code implementations14 Mar 2022 Kweku Kwegyir-Aggrey, A. Feder Cooper, Jessica Dai, John Dickerson, Keegan Hines, Suresh Venkatasubramanian

We study the problem of post-processing a supervised machine-learned regressor to maximize fair binary classification at all decision thresholds.

Shapley Residuals: Quantifying the limits of the Shapley value for explanations

no code implementations NeurIPS 2021 Indra Kumar, Carlos Scheidegger, Suresh Venkatasubramanian, Sorelle Friedler

Popular feature importance techniques compute additive approximations to nonlinear models by first defining a cooperative game describing the value of different subsets of the model's features, then calculating the resulting game's Shapley values to attribute credit additively between the features.

Precarity: Modeling the Long Term Effects of Compounded Decisions on Individual Instability

1 code implementation24 Apr 2021 Pegah Nokhiz, Aravinda Kanchana Ruwanpathirana, Neal Patwari, Suresh Venkatasubramanian

When it comes to studying the impacts of decision making, the research has been largely focused on examining the fairness of the decisions, the long-term effects of the decision pipelines, and utility-based perspectives considering both the decision-maker and the individuals.

Interdisciplinary Approaches to Understanding Artificial Intelligence's Impact on Society

no code implementations11 Dec 2020 Suresh Venkatasubramanian, Nadya Bliss, Helen Nissenbaum, Melanie Moses

Innovations in AI have focused primarily on the questions of "what" and "how"-algorithms for finding patterns in web searches, for instance-without adequate attention to the possible harms (such as privacy, bias, or manipulation) and without adequate consideration of the societal context in which these systems operate.

Fair clustering via equitable group representations

no code implementations19 Jun 2020 Mohsen Abbasi, Aditya Bhaskara, Suresh Venkatasubramanian

A core principle in most clustering problems is that a cluster center should be representative of the cluster it represents, by being "close" to the points associated with it.

Equalizing Recourse across Groups

no code implementations7 Sep 2019 Vivek Gupta, Pegah Nokhiz, Chitradeep Dutta Roy, Suresh Venkatasubramanian

We measure recourse as the distance of an individual from the decision boundary of a classifier.

Disentangling Influence: Using Disentangled Representations to Audit Model Predictions

1 code implementation NeurIPS 2019 Charles T. Marx, Richard Lanas Phillips, Sorelle A. Friedler, Carlos Scheidegger, Suresh Venkatasubramanian

Specifically, we show that disentangled representations provide a mechanism to identify proxy features in the dataset, while allowing an explicit computation of feature influence on either individual outcomes or aggregate-level outcomes.

Fairness in representation: quantifying stereotyping as a representational harm

no code implementations28 Jan 2019 Mohsen Abbasi, Sorelle A. Friedler, Carlos Scheidegger, Suresh Venkatasubramanian

While harms of allocation have been increasingly studied as part of the subfield of algorithmic fairness, harms of representation have received considerably less attention.

BIG-bench Machine Learning Fairness

A comparative study of fairness-enhancing interventions in machine learning

4 code implementations13 Feb 2018 Sorelle A. Friedler, Carlos Scheidegger, Suresh Venkatasubramanian, Sonam Choudhary, Evan P. Hamilton, Derek Roth

Concretely, we present the results of an open benchmark we have developed that lets us compare a number of different algorithms under a variety of fairness measures, and a large number of existing datasets.

Fair Pipelines

no code implementations3 Jul 2017 Amanda Bower, Sarah N. Kitchen, Laura Niss, Martin J. Strauss, Alexander Vargas, Suresh Venkatasubramanian

This work facilitates ensuring fairness of machine learning in the real world by decoupling fairness considerations in compound decisions.

Runaway Feedback Loops in Predictive Policing

1 code implementation29 Jun 2017 Danielle Ensign, Sorelle A. Friedler, Scott Neville, Carlos Scheidegger, Suresh Venkatasubramanian

Predictive policing systems are increasingly used to determine how to allocate police across a city in order to best prevent crime.

On the (im)possibility of fairness

2 code implementations23 Sep 2016 Sorelle A. Friedler, Carlos Scheidegger, Suresh Venkatasubramanian

We show that in order to prove desirable properties of the entire decision-making process, different mechanisms for fairness require different assumptions about the nature of the mapping from construct space to decision space.

A Unified View of Localized Kernel Learning

no code implementations4 Mar 2016 John Moeller, Sarathkrishna Swaminathan, Suresh Venkatasubramanian

Multiple Kernel Learning, or MKL, extends (kernelized) SVM by attempting to learn not only a classifier/regressor but also the best kernel for the training task, usually from a combination of existing kernel functions.

Auditing Black-box Models for Indirect Influence

2 code implementations23 Feb 2016 Philip Adler, Casey Falk, Sorelle A. Friedler, Gabriel Rybeck, Carlos Scheidegger, Brandon Smith, Suresh Venkatasubramanian

It is therefore hard to acquire a deeper understanding of model behavior, and in particular how different features influence the model prediction.

A Group Theoretic Perspective on Unsupervised Deep Learning

no code implementations8 Apr 2015 Arnab Paul, Suresh Venkatasubramanian

Over the shadow groups, the pre-training step, originally introduced as a mechanism to better initialize a network, becomes equivalent to a search for features with minimal orbits.

Why does Deep Learning work? - A perspective from Group Theory

Over the shadow groups, the pre-training step, originally introduced as a mechanism to better initialize a network, becomes equivalent to a search for features with minimal orbits.

Power to the Points: Validating Data Memberships in Clusterings

no code implementations21 May 2013 Parasaran Raman, Suresh Venkatasubramanian

It is also efficient: assigning an affinity score to a point depends only polynomially on the number of clusters and is independent of the number of points in the data.

1 code implementation INFORMS 2006 Tamraparni Dasu, Shankar Krishnan, Suresh Venkatasubramanian, Ke Yi

In this paper, we take a general, information-theoretic approach to the change detection problem, which works for multidimensional as well as categorical data.
