Unsupervised Detection of Adversarial Examples with Model Explanations

no code implementations22 Jul 2021 Gihyuk Ko, Gyumin Lim

From this insight, we propose an unsupervised detection of adversarial examples using reconstructor networks trained only on model explanations of benign examples.

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.
