Towards A Scalable Solution for Improving Multi-Group Fairness in Compositional Classification

no code implementations11 Jul 2023 James Atwood, Tina Tian, Ben Packer, Meghana Deodhar, Jilin Chen, Alex Beutel, Flavien Prost, Ahmad Beirami

Despite the rich literature on machine learning fairness, relatively little attention has been paid to remediating complex systems, where the final prediction is the combination of multiple classifiers and where multiple groups are present.

Fair treatment allocations in social networks

no code implementations1 Nov 2019 James Atwood, Hansa Srinivasan, Yoni Halpern, D. Sculley

Simulations of infectious disease spread have long been used to understand how epidemics evolve and how to effectively treat them.

Detecting Underspecification with Local Ensembles

2 code implementations ICLR 2020 David Madras, James Atwood, Alex D'Amour

We present local ensembles, a method for detecting underspecification -- when many possible predictors are consistent with the training data and model class -- at test time in a pre-trained model.

BriarPatches: Pixel-Space Interventions for Inducing Demographic Parity

no code implementations17 Dec 2018 Alexey A. Gritsenko, Alex D'Amour, James Atwood, Yoni Halpern, D. Sculley

We introduce the BriarPatch, a pixel-space intervention that obscures sensitive attributes from representations encoded in pre-trained classifiers.

No Classification without Representation: Assessing Geodiversity Issues in Open Data Sets for the Developing World

no code implementations22 Nov 2017 Shreya Shankar, Yoni Halpern, Eric Breck, James Atwood, Jimbo Wilson, D. Sculley

Further, we analyze classifiers trained on these data sets to assess the impact of these training distributions and find strong differences in the relative performance on images from different locales.

General Classification

Sparse Diffusion-Convolutional Neural Networks

no code implementations26 Oct 2017 James Atwood, Siddharth Pal, Don Towsley, Ananthram Swami

The predictive power and overall computational efficiency of Diffusion-convolutional neural networks make them an attractive choice for node classification tasks.
