PROJECTS

NYC Taxi Trip Duration Prediction 06/2019 - 09/2019

• Loaded 1.5 million taxi data on Google Cloud Platform and visualized the datasets by Folium map to facilitate data cleaning and feature engineering process.

• Generated new features: categorized pick-up and drop-off locations into 15 districts through K-means clustering; created categorical features based on pick-up datetimes.

• Incorporated additional features through National Weather Service and Open Source Routing Machine API.

• Eliminated outliers based on latitude and longitude, then selected critical features through PCA techniques.

• Built the trip duration prediction model with RMSLE of 0.213 by using LightGBM. Energy Prediction 03/2019 – 05/2019

• Retrieved the energy usage data from New York Independent System Operator and combined with the weather data from Dark Sky API to discover influential factors of the energy usage.

• Reorganized the weather datasets as five-minute time segmentation to match the energy usage datasets for generating date-time based features.

• Applied recursive feature elimination (RFE) technique to avoid overfitting and reduce the training time.

• Achieved 88% accuracy of the energy usage prediction based on a machine learning model, using random forests and linear regression algorithms. Quora Insincere Questions Classification 09/2018 - 12/2018

• Regularized Quora questions through removing non-representative words in Natural Language Toolkit, and then defined the keywords from the processed questions.

• Tokenized the above results into word vectors and applied neural language processing techniques to classify insincere questions.

• Built filters based on the user preference to further reduce irrelevant texts to improve the user experience. EXPERIENCE

Data Analyst Intern Industrial and Commercial Bank of China - Online i03/2019 - 06/2019

• Carried out researches and composed industry research reports of consumer loan market.

• Checked data and composed monthly tracking reports for credit card fraud detection.

• Created interactive Tableau dashboard to help production team and engineer team get better understanding about current feedbacks from customers and backlogs of the system. Teaching Assistant Georgia State University - Atlanta, GA i01/2018 - 05/2018

• Provided ready access to all experimental materials for the professor.
