Retail Operations Division Data Science Team Intern July 2019- September 2019

• Analyzed customer data with 800 variables, such as asset structure, capital flow and product purchased using SAS.

• Developed a model with XGBoost and Bayesian Optimization to predict customers’ likelihoods of purchasing financial products during current month, using last month’s data as training; predicted 20%+ correctly in August.

• Increased product sales by 15%+ after implementing different marketing strategies based on various probabilities generated. Top customers received individualized off-line marketing; others received general online marketing. PROJECTS __

Data Mining with R, UCLA November 2018- December 2018

• Implemented a statistical model with 3 teammates to predict housing affordability in Ames, Iowa; evaluated 10+ machine learning algorithms, such as Random Forest, Logistic Regression and Support Vector Machine.

• Predicted 98%+ of test data correctly after analyzing a training dataset with 80 variables and 3500 observations. Data Analysis and Experimental Design with R, UCLA January 2018- June 2018

• Led a group of 6 students to identify the predictors that best explained one’s happiness level.

• Developed a regression model that fit the dataset with 2000+ observations; wrote 250+ lines of codes and utilized statistical techniques such as inverse response plots, variable selection, added-variable plots and VIF.

• Designed an experiment with 7 teammates to analyze the effects of alcohol, chocolate and exercising on memory retention by implementing a 23

factorial design with blocking and examining features such as interaction plots. Hockey Playoffs – A Goalie’s Impact in the NHL, UCLA April 2019- June 2019

• Scraped data from hockey-reference.com with 2 teammates; used Python to analyze goalies’ impact in the NHL.
