Data Scientist Intern who worked with graph algorithms for bot detection and influencer detection.Key accomplishments:1) Performed multivariate and univariate analysis and train random forest for social media bot detection API.2) Constructed social network graph database from data stored on Redshift3) Used network graph algorithms to find communities of influencers as well as communities of botsTools: Python, Neo4j, SQL, Redshift, AWS

Work on projects and learn theory about the entire data pipeline, from data extraction (SQL, web-scraping) to data munging (pandas, numpy) to machine learning algorithms (sklearn). Also worked with big data tools and concepts, such as AWS, Spark, and Map Reduce.https://github.com/allenlu95/Tractor-Case-StudyBuilt a recommender system to recommend hilarious jokes. Includes use of NLP to process joke texts, NMF to explore latent features, and sparse matrix factorization for recommendation. https://github.com/allenlu95/Jokes-RecommenderBuilt a statistical model to predict customer churn for a ride sharing company with above 0.8 f1 score. Methodologies include logistic regression, Random Forest, Boosted Trees, and Ada-boost. https://github.com/allenlu95/Tractor-Case-StudyBuilt regression model to predict tractor prices at an auction. Performed feature engineering, feature selection , and grid-search among Lasso, Random Forest, and boosted models. https://github.com/allenlu95/Tractor-Case-Study
