Research of Yi Ma

Areas of Interest:

My main research interest is in finding the most pertinent mathematical principles for analyzing and understanding high-dimensional sensorial data such as images, so that machines and human can make more intelligent decisions. The research endeavor has led me into the following specific areas.

Computer Vision Mathematics & Statistics Decision & Control
- Multiple-View Geometry - Image & Video Segmentation - Object Recognition & Detection - Algebraic Sets and Manifolds - Data Clustering & Classification - Sparse Representation - Vision-Based Decision & Control - Identification of Hybrid Systems - Autonomous Robot Navigation

A recent essay by me reflecting on the methodology for research: Warning Signs of Bogus Research Progresses.

Powerpoint slides from a recent talk by me on How to do Research.
