Professional Activities

  • Software Engineering Intern with HP Vertica

    May 2015 – Aug. 2015

    I worked on the massively-distributed and highly-parallel columnar database system. Specifically, I applied robust optimization theory to database physical design. I implemented a robust physical design algorithm and integrate it with Vertica’s existing DBDesigner. The algorithm is able to maintain stable performance against perturbations in query workloads.

  • Student Volunteer of IEEE Infocom 2012.

    Mar. 2012

    I served to hand out badges, programs, and answer meeting-related questions from arriving registrants. I also assisted with setting up of the conference room, directing attendants towards the right program, and collecting and delivering evluation forms at the begining and end of the paper presentation.

  • Research Intern with Institute for Pattern Reconigtion and Artificial Intelligence, HUST.

    Sep. 2010 – Apr. 2011

    Reserach on automatic object recognition using template matching algorithms. We built 3D models of the scene and obtained sequences of object templates with different scales and views from simulations. Those templates were then used to find matches in videos of real scene to identify the desired target. We statistically evaluated the performance of different templates by varying the simulation environment and formulated principles for optimal selection of templates.

  • Research Intern with National Lab of Pattern Recognition, CASIA.

    Jul. 2009 ~ Aug. 2009

    I worked on an object classification research project during this internship. The object classfication algorithm we used is an emulation of the process of object recognition in primates’ visual cortex. A set of scale- and position- tolerant features were constructed to approximate the response properties of cells along the ventral stream of visual cortex. This work was accepted for publication in Proc. of CVPR. As a junoir undergraduate with only course work experience back then, I was able to grasp this new research topic in a very short time thanks to my strong motivation and solid academic background. I further devloped a system prototype with the object classification algorithm as the core. This system provides intuitive interface for visulizating and tweak various aspects of the algorithm.
