My name is Zhang Yuanhang (Chinese: “张远航”). I received my bachelor’s degree in Computer Science from University of Chinese Academy of Sciences in 2019. Currently, I am a third-year Ph.D. student at VIPL Group, Institute of Computing Technology (ICT), Chinese Academy of Sciences (CAS) , supervised by Prof. Shiguang Shan and Prof. Shuang Yang. My main research interests are deep learning applications that combine vision and language, as well as multi-modal and self-supervised learning. I have also worked on interdisciplinary projects with Prof. Qun Zheng from Department of Foreign Languages, University of Chinese Academy of Sciences, where we attempt to build an automated spoken English rating system based on interpretable discourse coherence indicators.

This website features a collection of lecture notes and reference material I gathered or compiled while studying at UCAS, which I hope future students find useful. Sometimes I also write short surveys of recent research advances, or post Chinese translations for academic contents that are of interest. I honed much of my English skills working as a translator and proofreader at ACI Chinese Fansub Group (ACICFG) over the past decade.
