Feature-Wise Bias Amplification

no code implementations ICLR 2019 Klas Leino, Emily Black, Matt Fredrikson, Shayak Sen, Anupam Datta

This overestimation gives rise to feature-wise bias amplification -- a previously unreported form of bias that can be traced back to the features of a trained model.

Supervising Feature Influence

no code implementations28 Mar 2018 Shayak Sen, Piotr Mardziel, Anupam Datta, Matthew Fredrikson

Standard methods for training classifiers that minimize empirical risk do not constrain the behavior of the classifier on such datapoints.

Influence-Directed Explanations for Deep Convolutional Networks

2 code implementations ICLR 2018 Klas Leino, Shayak Sen, Anupam Datta, Matt Fredrikson, Linyi Li

We study the problem of explaining a rich class of behavioral properties of deep neural networks.

Latent Factor Interpretations for Collaborative Filtering

no code implementations29 Nov 2017 Anupam Datta, Sophia Kovaleva, Piotr Mardziel, Shayak Sen

The interpretation of latent factors can then replace the uninterpreted latent factors, resulting in a new model that expresses predictions in terms of interpretable features.

Case Study: Explaining Diabetic Retinopathy Detection Deep CNNs via Integrated Gradients

no code implementations27 Sep 2017 Linyi Li, Matt Fredrikson, Shayak Sen, Anupam Datta

In this report, we applied integrated gradients to explaining a neural network for diabetic retinopathy detection.

Proxy Non-Discrimination in Data-Driven Systems

3 code implementations25 Jul 2017 Anupam Datta, Matt Fredrikson, Gihyuk Ko, Piotr Mardziel, Shayak Sen

Machine learnt systems inherit biases against protected classes, historically disparaged groups, from training data.

Use Privacy in Data-Driven Systems: Theory and Experiments with Machine Learnt Programs

no code implementations22 May 2017 Anupam Datta, Matthew Fredrikson, Gihyuk Ko, Piotr Mardziel, Shayak Sen

For a specific instantiation of this definition, we present a program analysis technique that detects instances of proxy use in a model, and provides a witness that identifies which parts of the corresponding program exhibit the behavior.

Debugging Machine Learning Tasks

no code implementations23 Mar 2016 Aleksandar Chakarov, Aditya Nori, Sriram Rajamani, Shayak Sen, Deepak Vijaykeerthy

Unlike traditional programs (such as operating systems or word processors) which have large amounts of code, machine learning tasks use programs with relatively small amounts of code (written in machine learning libraries), but voluminous amounts of data.
