Emission-Control-Global-Warming-Analysis-and-Prediction
This project is about energy efficiency and renewable energy topic. Developed multivariate time series model to forecast global warming. Analyzed various causes of global warming including energy consumption, emissions; examined correlation and causality of temperature, CO2 concentration, population time series. Discovered the logical connections, contributory factors, etc.
Analysis-and-Classification-of-Restaurant-Reviews
Developed a NLP classification model that can classify negative reviews of restaurants, help restaurant managers save time on reviewing comments, absorbing information. Analyze the service defects, help restaurants improve business
Analysis-of-Diamond-Features-and-Price-Prediction
The goals of this project are to establish machine learning model to predict diamonds prices, and use the model to check if online diamonds retailer websites have better prices or overcharge customers. In this project, various attributes of diamonds are analyzed by EDA, descriptive statistics and statistical tests to see how they influence values of diamonds. Also, prediction models are evaluated by RMSE and Z-Score to get the best model.
Bank-Telemarketing-Outcome-Prediction-and-Decision-Support
Developed machine learning models that can help bank tellers to predict telemarketing campaign response from clients. Analyzed precision-recall trade off, customized for models for different business scenarios
