I will be starting as an assistant professor of CS at Rice University in Fall 2018.
Simple algorithms for low-rank approximations at UAI 2018.
IHT-dies-hard paper got accepted at AISTATS 2018.
Statistical inference using SGD got accepted at AAAI 2018.
Setting up a Nvidia GPU-equipped computer
Very roughly, there are two trends in deep learning research: one is on applications (check the vast volume of new papers in the ArXiv RSS feeds of Learning Theory, Machine Learning; even Optimization). The other is understanding how to train/set up a deep neural network. The latter is exactly what creates doubts to/worries/concerns/interests me. We have (almost) no idea why these tools work and how we should train them.

Non-convex workshop at ICML 2016 - Part I
With this blog post, I want to summarize the key points presented at the ICML 2016 workshop Advances in non-convex analysis and optimization, hosted by Animashree Anandkumar, Sivaraman Balakrishnan, Srinadh Bhojanapalli, Kamalika Chaudhuri, Yudong Chen, Percy Liang, Praneeth Netrapalli, Sewoong Oh, Zhaoran Wang, and me.
Papers in ICML 2016 & COLT 2016
Workshop on non-convex methods at ICML 2016!
Simons Seminar at UT
This semester I’m co-organizing the Simons seminar at UT Austin.
Telling a story about IHT using Python (Chapter II)
In this notebook, $(i)$ we will further dive in the original IHT scheme and note some of its pros/cons in solving the CS problem, and $(ii)$ we will provide an overview of more recent developments on constant step size selection for IHT.
Three papers accepted to AISTATS 2016
Telling a story about IHT using Python (Chapter I)
The purpose of this notebook is 2-fold: $(i)$ Since this is the first attempt to “migrate” from Matlab-type-of-mathematical-programming language to Python language, this very first notebook serves as a guide for future posts. $(ii)$ This is a loooong post that presents Iterative Hard Thresholding (IHT) algorithm and its variants, a method that solves Compressive Sensing problems in the non-convex setting.
Seminars at UT
This semester I’m co-organizing two seminars at UT Austin.
New webpage (under construction)
Hello everyone! I’m currently editing my new webpage. The aim is to include blog posts, most of the projects I have worked on (with codes included), updates on my publications and other.
