di-tech_algorithm_challenge_2016

Didi Taxi is a mobile platform taxi-calling application in China. It has acquired Uber's China operations in 2016 with the capital from Apple. It hosted an machine learning algorithm contest in 2016 in order to solve the demand-supply problem of Didi taxi. I took part in the contest in 2016 when I was still studying at Duke University. This is my solution to the problem. My teammates also includes Guotu Li from Duke University and Jianhai Zhang from Dalian University of Technology.
