Predicting Properties of Quantum Systems with Conditional Generative Models

1 code implementation30 Nov 2022 Haoxiang Wang, Maurice Weber, Josh Izaac, Cedric Yen-Yu Lin

For many ground states of gapped Hamiltonians, generative models can learn from measurements of a single quantum state to reconstruct the state accurately enough to predict local observables.

Certifying Some Distributional Fairness with Subpopulation Decomposition

1 code implementation31 May 2022 Mintong Kang, Linyi Li, Maurice Weber, Yang Liu, Ce Zhang, Bo Li

In this paper, we first formulate the certified fairness of an ML model trained on a given data distribution as an optimization problem based on the model performance loss bound on a fairness constrained distribution, which is within bounded distributional distance with the training distribution.

Certifying Out-of-Domain Generalization for Blackbox Functions

1 code implementation3 Feb 2022 Maurice Weber, Linyi Li, Boxin Wang, Zhikuan Zhao, Bo Li, Ce Zhang

As a result, the wider application of these techniques is currently limited by its scalability and flexibility -- these techniques often do not scale to large-scale datasets with modern deep neural networks or cannot handle loss functions which may be non-smooth such as the 0-1 loss.

Optimal Provable Robustness of Quantum Classification via Quantum Hypothesis Testing

no code implementations21 Sep 2020 Maurice Weber, Nana Liu, Bo Li, Ce Zhang, Zhikuan Zhao

This link leads to a tight robustness condition which puts constraints on the amount of noise a classifier can tolerate, independent of whether the noise source is natural or adversarial.

RAB: Provable Robustness Against Backdoor Attacks

1 code implementation19 Mar 2020 Maurice Weber, Xiaojun Xu, Bojan Karlaš, Ce Zhang, Bo Li

In addition, we theoretically show that it is possible to train the robust smoothed models efficiently for simple models such as K-nearest neighbor classifiers, and we propose an exact smooth-training algorithm that eliminates the need to sample from a noise distribution for such models.

TSS: Transformation-Specific Smoothing for Robustness Certification

1 code implementation27 Feb 2020 Linyi Li, Maurice Weber, Xiaojun Xu, Luka Rimanic, Bhavya Kailkhura, Tao Xie, Ce Zhang, Bo Li

Moreover, to the best of our knowledge, TSS is the first approach that achieves nontrivial certified robustness on the large-scale ImageNet dataset.

Observer Dependent Lossy Image Compression

1 code implementation8 Oct 2019 Maurice Weber, Cedric Renggli, Helmut Grabner, Ce Zhang

To that end, we use a family of loss functions that allows to optimize deep image compression depending on the observer and to interpolate between human perceived visual quality and classification accuracy, enabling a more unified view on image compression.
