Minimax Defense against Gradient-based Adversarial Attacks

no code implementations4 Feb 2020 Blerta Lindqvist, Rauf Izmailov

Our Minimax adversarial approach presents a significant shift in defense strategy for neural network classifiers.

Privacy Leakage Avoidance with Switching Ensembles

no code implementations18 Nov 2019 Rauf Izmailov, Peter Lin, Chris Mesterharm, Samyadeep Basu

We consider membership inference attacks, one of the main privacy issues in machine learning.

Membership Model Inversion Attacks for Deep Networks

no code implementations9 Oct 2019 Samyadeep Basu, Rauf Izmailov, Chris Mesterharm

With the increasing adoption of AI, inherent security and privacy vulnerabilities formachine learning systems are being discovered.

Subspace Methods That Are Resistant to a Limited Number of Features Corrupted by an Adversary

no code implementations19 Feb 2019 Chris Mesterharm, Rauf Izmailov, Scott Alexander, Simon Tsang

In this paper, we consider batch supervised learning where an adversary is allowed to corrupt instances with arbitrarily large noise.

AutoGAN: Robust Classifier Against Adversarial Attacks

no code implementations8 Dec 2018 Blerta Lindqvist, Shridatt Sugrim, Rauf Izmailov

For different magnitudes of perturbation in training and testing, AutoGAN can surpass the accuracy of FGSM method by up to 25\% points on samples perturbed using FGSM.

Detection under Privileged Information

no code implementations31 Mar 2016 Z. Berkay Celik, Patrick McDaniel, Rauf Izmailov, Nicolas Papernot, Ryan Sheatsley, Raquel Alvarez, Ananthram Swami

In this paper, we consider an alternate learning approach that trains models using "privileged" information--features available at training time but not at runtime--to improve the accuracy and resilience of detection systems.

Multi-Scale Local Shape Analysis and Feature Selection in Machine Learning Applications

no code implementations13 Oct 2014 Paul Bendich, Ellen Gasparovic, John Harer, Rauf Izmailov, Linda Ness

We introduce a method called multi-scale local shape analysis, or MLSA, for extracting features that describe the local structure of points within a dataset.

Constructive Setting of the Density Ratio Estimation Problem and its Rigorous Solution

no code implementations3 Jun 2013 Vladimir Vapnik, Igor Braga, Rauf Izmailov

We introduce a general constructive setting of the density ratio estimation problem as a solution of a (multidimensional) integral equation.
