Jian Wang was a research assistant in Computer Science and Engineering at Nanyang Technological University since 2019. Previously, he was a researcher at Xiaomi AI Lab and an engineer who worked at 58.Inc and Baidu.Inc.

Jian Wang received a B.A. in Software Engineering from Tianjin University, China.

Jian Wang's research interests include machine learning algorithms and theory, adversarial methods for privacy data, and their applications. His specific interest is in Security Analysis, Trending Analysis, and Privacy Protection.
He is now heavily engaged in robust AI by creating high-realism adversarial attacks/defence such as trace-based repair for defence, adversarial motion blur for attacking, facial-skew adversarial for deepfake detection, etc.

Representative papers are highlighted.

PDF / bibtex / Poster

We propose a lightweight model-based influence analysis, to help understand and repair incorrect behaviors of an RNN. Specifically, we first build an automaton to enable high-quality feature extraction and to characterize the stateful and statistical behaviors of an RNN over all the training data.

Media Coverage: Synced Review

Monitoring neuron behavior can serve as an asset in detecting AI-synthesized fake faces since layer-by-layer neuron activation patterns may capture more subtle features that are important for the fake detector. -- by Xu.Juefei
