PDEs & Data Control Seminar

PDEs & Data Control Seminar

The goal of this seminar is multifold: (i) provide training to undergraduate and graduate students; (ii) learn new and exciting topics which are of wider interest. Typically, students and postdocs take the lead and present the material chosen at the beginning of the semester. The seminar covers topics in PDEs, Optimization, Data Science, Scientific Computing, Probability, and Machine Learning. 

Everyone is welcome to attend. For questions, please contact Harbir Antil at hantil@gmu.edu.

Fall 2019

The plan for this semester is to go through the new book Linear Algebra and Learning from Data by Gilbert Strang. 
One can find the contents of the book here. The material we plan to cover includes:
Chapter III: Low rank and compressed sensing
Chapter VI: Optimization
Chapter VII: Learning from data
