On Breaking Deep Generative Model-based Defenses and Beyond

1 code implementation ICML 2020 Yanzhi Chen, Renjie Xie, Zhanxing Zhu

The idea is to view the inversion phase as a dynamical system, through which we extract the gradient with respect to the input by tracing its recent trajectory.

Scalable Infomin Learning

1 code implementation21 Feb 2023 Yanzhi Chen, Weihao Sun, Yingzhen Li, Adrian Weller

The task of infomin learning aims to learn a representation with high utility while being uninformative about a specified target, with the latter achieved by minimising the mutual information between the representation and the target.

Domain Adaptation Fairness +1

A Generalizable Model-and-Data Driven Approach for Open-Set RFF Authentication

1 code implementation10 Aug 2021 Renjie Xie, Wei Xu, Yanzhi Chen, Jiabao Yu, Aiqun Hu, Derrick Wing Kwan Ng, A. Lee Swindlehurst

To enable the discrimination of RFF from both known and unknown devices, we propose a new end-to-end deep learning framework for extracting RFFs from raw received signals.

Inductive Bias

Do Concept Bottleneck Models Learn as Intended?

no code implementations10 May 2021 Andrei Margeloiu, Matthew Ashman, Umang Bhatt, Yanzhi Chen, Mateja Jamnik, Adrian Weller

Concept bottleneck models map from raw inputs to concepts, and then from concepts to targets.

Neural Approximate Sufficient Statistics for Likelihood-free Inference

no code implementations ICLR 2021 Yanzhi Chen, Dinghuai Zhang, Michael U. Gutmann, Aaron Courville, Zhanxing Zhu

We consider the fundamental problem of how to automatically construct summary statistics for likelihood-free inference where the evaluation of likelihood function is intractable but sampling / simulating data from the model is possible.

Neural Approximate Sufficient Statistics for Implicit Models

1 code implementation20 Oct 2020 Yanzhi Chen, Dinghuai Zhang, Michael Gutmann, Aaron Courville, Zhanxing Zhu

We consider the fundamental problem of how to automatically construct summary statistics for implicit generative models where the evaluation of the likelihood function is intractable, but sampling data from the model is possible.

Adaptive Gaussian Copula ABC

no code implementations27 Feb 2019 Yanzhi Chen, Michael U. Gutmann

Approximate Bayesian computation (ABC) is a set of techniques for Bayesian inference when the likelihood is intractable but sampling from the model is possible.

Bayesian Inference

A Deep, Information-theoretic Framework for Robust Biometric Recognition

no code implementations23 Feb 2019 Renjie Xie, Yanzhi Chen, Yan Wo, Qiao Wang

Deep neural networks (DNN) have been a de facto standard for nowadays biometric recognition solutions.
