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.

Improving Certified Robustness via Statistical Learning with Logical Reasoning

1 code implementation28 Feb 2020 Zhuolin Yang, Zhikuan Zhao, Boxin Wang, Jiawei Zhang, Linyi Li, Hengzhi Pei, Bojan Karlas, Ji Liu, Heng Guo, Ce Zhang, Bo Li

Intensive algorithmic efforts have been made to enable the rapid improvements of certificated robustness for complex ML models recently.

Bayesian Deep Learning on a Quantum Computer

2 code implementations29 Jun 2018 Zhikuan Zhao, Alejandro Pozas-Kerstjens, Patrick Rebentrost, Peter Wittek

Furthermore, we demonstrate the execution of the algorithm on contemporary quantum computers and analyze its robustness with respect to realistic noise models.

Gaussian Processes

Quantum assisted Gaussian process regression

no code implementations12 Dec 2015 Zhikuan Zhao, Jack K. Fitzsimons, Joseph F. Fitzsimons

We show that even in some cases not ideally suited to the quantum linear systems algorithm, a polynomial increase in efficiency still occurs.
