About me

I am advised by Professor Pulkit Grover and Professor Soummya Kar.

Before I joined CMU I was an undergraduate student in the Department of Electronic Engineering, Tsinghua University

My resume is available HERE.


  • Our paper Fast Temporal Path Localization on Graphs via Multiscale Viterbi Decoding is accepted by IEEE Transactions on Signal Processing! The paper investigates the problem of localizing a moving agent on a graph from noisy temporal observations. By aggregating the observed information on multiple timestamps (in the form of temporal graph signals), we are able to accurately localize the trajectory of the moving agent. The main novelty of the paper is to use graph partitioning techniques to speed up Viterbi decoding (or general dynamic programming techniques on graphs).  The arxiv paper is here. 
  • We gave a talk in ISIT 2018 on coded computing for general iterative computation. Compared to previous works, we show that the convergence behavior of iterative computing can be explicitly used in the design of coded computing techniques. We show that when a novel decoding technique called "substitute decoding" is used, the fault tolerance can be increased significantly. The arxiv paper is here.
  • Our work FoldingNet was selected as a spotlight talk in CVPR 2018! You can see a video here. The code and the paper are also released. It shows that transforming a regular grid into the shape of a point cloud can provide useful point cloud decoder with state-of-the-art unsupervised learning ability. We also have a concurrent paper in CVPR 2018 called KCNet here with code release. KCnet provides a novel way of exploiting neighborhood structures in point clouds using graph-based and kernel-correlation-based techniques.
