Research Intern, Institute of Quantum Computing, Waterloo, Canada, 2013

• Developed, documented, and maintained Matlab program to simulate the physical process of electron and nuclear double resonance;

• Communicated with the experimental team to modify the theoretical model based on real experimental data.

Projects Instacart Market Basket Analysis

• Exploratory data analysis on history transaction record to extract statistics on each user and product;

• Built a machine learning model to predict whether an item will be ordered by the same user, based on xgboost classifier. Achieved a result of 0.382 in the metric of F1-score. NYC Taxi Trip Duration Prediction

• Cleaned, explored, and visualized over 1 million taxi trip records in Jupyter;

• Divided NYC map into different areas by using K-Means and DBSCAN clustering algorithms on taxi pick-up and drop-off location data;

• Extracted statistics on trip duration in different scenarios;

• Predictive modeling based on gradient boosting regression. Deep Reinforcement Learning for Multi-Agent Soccer

• Investigated and implemented Deep Reinforcement Opponent Network(DRON), an expanded version of deep Q-network, for modeling the primal agent, the team agents, and opponents policy simultaneously on a multiagent task of 2D soccer game.
