About Me (CV)

I was a master student at ShanghaiTech, advised by Professor Manolis. I did my undergraduate at Zhejiang University.

I seek mathematical or algorithmic answers to the questions that arise in machine learning, computer vision, signal processing. The problems of interest to me include (but are not limited to)

1. homomorphic sensing (read this)
1.1. real phase retrieval
1.2. symmetric mixture of two linear regressions
1.3. unlabeled sensing
1.3.1. linear regression without correspondences
1.3.2. unlabeled ordered sensing
2. point set registration
3. matrix completion
4. robust PCA

In research I use tools from algebraic geometry and optimization. I am conducting research into homomorphic sensing using algebraic-geometric methods.
