Gizwits, Guangzhou, China 2016.07-2016.08

Algorithm Engineer Intern

Research on anomaly detection algorithm in the AI team for Gizwits showcase.

Updated parameter-free and window comparison anomaly detection algorithm by SAX transformation and window size determination, which successfully found out NY taxi data’s top 5 anomaly periods due to festival or weather.

Performed data cleaning and exploratory data analysis on Huashang Sanyou charging piles data in prepare of project negotiating.

Transport Planning Research Institute, Guangzhou, China 2016.06 Megalopolitan Coordinate Analysis Project

Gathered various related data of 38 megalopolises, perform dimension reduction for visualization requirements.

Solved the interpretation problem by performing hierarchical clustering, produced dendrogram which provides reasonable reference direction for Guangzhou’s future development.

Update original model by abandoning entropy weight method, using sparse PCA and correlation-based distance, and organizing all the results for final analysis report. Urban Transportation Research Center, Beijing, China 2013.07-2013.08 TOD Project

Participated in the formulation of the transportation development and construction plan of Kunming, Yunnan Province.

Predicted passenger flow in PT Hub in order to provide basis for rationally specifying construction scale of the public transport hub and transport connection means.

Assisted in making public transportation model of Kunming, Yunnan Province. EXTRACURRICULAR EXPERIENCE

Advanced Data Analysis Project, Columbia University 2016.10-2016.12
