My CV and google citation page.
I have general research interests in machine learning, statistics, optimization and signal processing. Particularly, I am interested in the connection between optimization/spectral methods, low-rank structures, and the underlying spectrum.
Theoretically speaking, instead of establishing consistency or convergence rates under idealized models or strong assumptions, I am currently interested in exploring low-assumption or assumptionless frameworks to understand the methods of study in terms of efficacy, efficiency, limitation, and adaptivity.
I have been actively working in the following topics:
- Unsupervised learning
- Multivariate statistical analysis
- Convex and nonconvex optimization
- Imaging and signal processing
- Network analysis
