September 2019-December 2019

Analyze Los Angeles Traffic Collision data sets (large data sets 488K rows) from Kaggle: R

Area of interest: Random Forest, XGBoost, K-means clustering, Logistic regression, Time Series

Data cleaning, data manipulation, detect outliers, handling missing data, combining categories, and check collinearity.

Exponential smoothing and holt’s methods showed decreasing trends for last years.

Under-sampling, up-sampling, SMOTE used for unbalanced data classification.

Classification (logistic regression, KNN, decision trees) found that time and location is an important factor for a car accident.

Random forest, XGBoost predicted that time is the most significant impact to predict DUI(Driving under influence) and hit and run.

K-means clustering group people by gender, age, race. Cluster 2 group showed highest parking lot accidents compare to other groups. LA city can provide this group for extra parking education

October 2019 – December 2019

Analyze Bank Marketing Data Set from UCI machine learning repository: R

Area of interest: Random Forest, XGBoost, K-means clustering, Logistic regression

ggplot for data visualization and dplyr for data exploration and data cleaning.

Collinearity showed employment is highly related to interest.

Under-sampling, SMOTE, over-sampling for unbalanced data classification.

Experiment for 0.5 and 0.3 cutoff for classification.

Classification using KNN, decision trees, logistic regression to predict telephone marketing result.

Random forest and XGBoost showed call duration, and interest rate were the most important factors to predict the success of customer subscription of term deposit.

XGBoost achieved the highest sensitivity (93%) among all the models showing the call duration is the most important factor at 0.5 cutoff.
