Efficient Identification in Linear Structural Causal Models with Instrumental Cutsets

1 code implementation NeurIPS 2019 Daniel Kumor, Bryant Chen, Elias Bareinboim

Building on the literature of instrumental variables (IVs), a plethora of methods has been developed to identify causal effects in linear systems.

A Unifying Causal Framework for Analyzing Dataset Shift-stable Learning Algorithms

no code implementations27 May 2019 Adarsh Subbaswamy, Bryant Chen, Suchi Saria

Recent interest in the external validity of prediction models (i. e., the problem of different train and test distributions, known as dataset shift) has produced many methods for finding predictive distributions that are invariant to dataset shifts and can be used for prediction in new, unseen environments.

Detecting Backdoor Attacks on Deep Neural Networks by Activation Clustering

1 code implementation9 Nov 2018 Bryant Chen, Wilka Carvalho, Nathalie Baracaldo, Heiko Ludwig, Benjamin Edwards, Taesung Lee, Ian Molloy, Biplav Srivastava

While machine learning (ML) models are being increasingly trusted to make decisions in different and varying areas, the safety of systems using such models has become an increasing concern.

Adversarial Robustness Toolbox v1.0.0

5 code implementations3 Jul 2018 Maria-Irina Nicolae, Mathieu Sinn, Minh Ngoc Tran, Beat Buesser, Ambrish Rawat, Martin Wistuba, Valentina Zantedeschi, Nathalie Baracaldo, Bryant Chen, Heiko Ludwig, Ian M. Molloy, Ben Edwards

Defending Machine Learning models involves certifying and verifying model robustness and model hardening with approaches such as pre-processing inputs, augmenting training data with adversarial samples, and leveraging runtime detection methods to flag any inputs that might have been modified by an adversary.

Identification and Model Testing in Linear Structural Equation Models using Auxiliary Variables

no code implementations ICML 2017 Bryant Chen, Daniel Kumor, Elias Bareinboim

In this paper, we provide an algorithm for the identification of causal parameters in linear structural models that subsumes previous state-of-the-art methods.

Identification and Overidentification of Linear Structural Equation Models

no code implementations NeurIPS 2016 Bryant Chen

In this paper, we address the problems of identifying linear structural equation models and discovering the constraints they imply.

Incorporating Knowledge into Structural Equation Models using Auxiliary Variables

no code implementations10 Nov 2015 Bryant Chen, Judea Pearl, Elias Bareinboim

This cancellation allows the auxiliary variables to help conventional methods of identification (e. g., single-door criterion, instrumental variables, half-trek criterion), as well as model testing (e. g., d-separation, over-identification).

Decomposition and Identification of Linear Structural Equation Models

no code implementations7 Aug 2015 Bryant Chen
