Meng Fang

I am an Assistant Professor in Machine Learning at University of Liverpool. I'm also a visiting researcher at Eindhoven University of Technology (TU/e). I received my Ph.D from University of Technology Sydney, advised by Prof. Dacheng Tao. I was also supervised by Prof. Xingquan Zhu and Dr. Jie Yin at UTS. I was a postdoctoral research fellow working with Prof. Trevor Cohn. I had been a research scientist/intern at Tencent AI, CSIRO and Microsoft Research Asia before.

My research focus is on building human-like agents with language and control.

Multi-goal reinforcement learning
TL;DR: We propose new methods and environments for multi-goal settings with sparse rewards.
Keywords: sparse rewards, sample efficient. [project page]

Text-based games
TL;DR: We consider the task of learning control policies for text-based games.
Keywords: knowledge graphs, attention, RL, hierarchical RL. [project page]

Question & Answering
TL;DR: We consider the reasoning process for question and answering problems.
Keywords: graphs, graph neural networks, knowledge graphs. [project page]
