Biography

I am currently an MPhil student in AI under the supervision of Prof. Li Liu at HKUST(GZ) and the co-supervision of Prof. Yi R. (May) Fung at HKUST. Previously, after getting my MSc CS degree from HKU, I used to work as a full-time research assistant at Applied Security, Trust And Privacy Lab for Enterprise of PolyU under the supervision of Prof. Haibo Hu. During my undergraduate time at ECNU, I also participated in part-time research at Shanghai Key Laboratory of Trustworthy Computing under the supervision of Prof. Dehui Du. It is also my great pleasure to work with close co-authors Zi Liang, Weilin Lin, and Nanjun Zhou.

Reading Note of the Paper "A Survey on Neural Speech Synthesis"
Text-to-speech (TTS), also known as speech synthesis, aims to synthesize intelligible and natural speech from text. Neural TTS adopts DNNs as the model backbone for speech synthesis.

Reading Note of the Paper "Membership Inference Attacks on Machine Learning - A Survey"
Membership Inference Attack (MIA) is to infer whether a data record was used to train a target model or not. MIAs on ML models can directly lead to a privacy breach.

Reading Note of the Paper "Survey - Leakage and Privacy at Inference Time"
Leakage of data from publicly available ML models is an area of growing significance since it can draw on multiple sources of data, including users’ sensitive data.
