Certified Federated Adversarial Training

no code implementations20 Dec 2021 Giulio Zizzo, Ambrish Rawat, Mathieu Sinn, Sergio Maffeis, Chris Hankin

We model an attacker who poisons the model to insert a weakness into the adversarial training such that the model displays apparent adversarial robustness, while the attacker can exploit the inserted weakness to bypass the adversarial training and force the model to misclassify adversarial examples.

Automated Robustness with Adversarial Training as a Post-Processing Step

no code implementations6 Sep 2021 Ambrish Rawat, Mathieu Sinn, Beat Buesser

Adversarial training is a computationally expensive task and hence searching for neural network architectures with robustness as the criterion can be challenging.

Castor: Contextual IoT Time Series Data and Model Management at Scale

1 code implementation20 Nov 2018 Bei Chen, Bradley Eck, Francesco Fusco, Robert Gormally, Mark Purcell, Mathieu Sinn, Seshu Tirupathi

The main features of Castor are: (1) an efficient pipeline for ingesting IoT time series data in real time; (2) a scalable, hybrid data management service for both time series and contextual data; (3) a versatile semantic model for contextual information which can be easily adopted to different application domains; (4) an abstract framework for developing and storing predictive models in R or Python; (5) deployment services which automatically train and/or score predictive models upon user-defined conditions.

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.

Mixing Properties of Conditional Markov Chains with Unbounded Feature Functions

no code implementations NeurIPS 2012 Mathieu Sinn, Bei Chen

Conditional Markov Chains (also known as Linear-Chain Conditional Random Fields in the literature) are a versatile class of discriminative models for the distribution of a sequence of hidden states conditional on a sequence of observable variables.

Adaptive Learning of Smoothing Functions: Application to Electricity Load Forecasting

no code implementations NeurIPS 2012 Amadou Ba, Mathieu Sinn, Yannig Goude, Pascal Pompey

In order to quickly track changes in the model and put more weight on recent data, the RLS filter uses a forgetting factor which exponentially weights down observations by the order of their arrival.
