About me

I am currently a fifth year PhD student in Department of Computer science in The University of Iowa (Hawkeye), working with Prof. Tianbao Yang. I received my bachelor's degree and master's degree both in computer science from Xian Jiaotong University and South Dakota State University(Jackrabbits) in 2010 and 2013, respectively.

News

  • I will give a guest lecture on automatically searching the optimal neural network structures in deep learning course at The University of Iowa.

  • We gave a presentation on our oral AISTATS 2018 paper.

  • I gave a guest lecture on comressing deep neural networks in deep learning course at The University of Iowa.

Research Interest

alt text 

My research interests fall into three levels (as shown in the left figure):

  • understanding why machine can learn from learning theory perspective (statistical machine learning);

  • designing and analyzing optimization algorithms to facilate machine learning effeciently;

  • utilizing machine learning models(Specifically, deep neural network) to solve image classification, object detection or other computer vision task.

  • “Deep Learning With Caffe”[pdf], The University of Iowa, Apr 2017
    This lecture tried to teach students widely from The university of Iowa how to install caffe in the university cluster argon and how to train the very first deep neural network model for image classification using caffe. The installation in Argon clusteris quite tricky since students don't have root access to cluster. See Notes for detail information if you want to install caffe in your cluster environment.

Demo

  • Object Detection: This is C++ implementation of RCNN based on caffe framework, in which sliding window, bounding box regression are utilized.
