1. Intro to MVPA methods for neuroimaging data

I am organizing the brain imaging unit at the Knowledge and Concepts Lab, directed by Professor Tim Rogers. This is a tutorial (in progress) that introduces people to MVPA methods. To tackle the underdeterminacy of neuroimaging data without pre-defining ROIs, I will focus on sparse methods, such as Logistic LASSO.


2. Approximate L0 solution with iterative L1 reweighting

This is a tutorial I wrote when I was taking ECE 532 Theory and Applications of Pattern Recognition, taught by Professor Robert Nowak and Professor Laurent Lessard at UW-Madison. I will re-write and upate this document in the future. You are welcome to read it if you don't mind the typos...
