Qiqi Hou
I am a machine learning researcher at Qualcomm AI Research. Much of my current research is about the applications of deep learning, such as data compression, Monte Carlo rendering, perceptual quality metrics, frame interpolation, matting, face landmark detection and etc. Before that, I received my Ph.D. and M.E. degrees from Portland State University and Xi'an Jiaotong University in 2023 and 2017, respectively, where I was advised by Feng Liu and Jinjun Wang , respectively.
