Qiqi Hou
I am a machine learning researcher at Qualcomm AI Research. Much of my current research is about computer vision and computer graphics, such as LVM, 3DGS, stable diffusion, data compression, 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.
