Master Dissertation: Low-Latency MapReduce By Xiaoran Li and Zhiying Wang
Coded Distributed Computation. Designed algorithm to make deep learning and distributed computation(inner product, convolution) robust, salable and private with code theory under supervision of Prof. Zhiying Wang as graduate research assistant.
Low-latency MapReduce. Designed algorithms(pair-index \& index-pair) to shorten overall system delay in shuffling phase for 10% in a distributed cloud storage system.
Word Search: Designed algorithm to develop a LAN to simulate enterprise distributed file system with total size of 20GB and find communication cost between each server.
Recommendation Search. Designed algorithms to do recommendations based on web crawler collect website information from UCI website, and collected recommendation from UCI domain.
Image Search. Designed algorithms to match image from services by building a 11-layer network.

Tested gun cannon collision experiment to find the material that not exsist in the natural setting on Earth. Then
collected data in a cloud data sheet and plot the result by using linear regression which helps to find how materials can be compose in specific way.
