tesla-stock-price-prediction-

This project was completed with the intention of helping Tesla stock investors better understand how to make decisions where the stock market is very volatile by training different models through historical and social media data analytics. Behavioral economics shows that public emotions can profoundly affect individual behavior and decision making. In order for investors to utilize it, business analysts must understand the behaviors and attitudes of the public within the finance context. Nowadays, social media perfectly tracked by data reflects the public emotions and sentiment about stock movement. Also, tremendous stock marketing news can be used to capture a trend of stock movement. The fundamental trading and decision making for main techniques rely on expert training and prediction. This article concentrated on tweets and stock news, and I applied sentiment analysis and machine learning models, especially, XGBoost to tweets and news extracted from Elon Musk tweets, Nasdaq and New York Times News about Tesla. Only by understanding the values and priorities of the public sentiment of Tesla stock will investors be able to make significant decisions. In addition, I conducted two models- ARIMA and RNN(LSTM) in forecasting the Tesla stock price. I compare their results with the prediction performances of the classical ARIMA and RNN.

Identifying the circumstances under what features affect accident severity and which areas have high accident rates can help insurance companies predict premium and budget of expenditure. To understand factors influencing the severity of US car accidents, including location and weather-related conditions, several classification models were developed. This project focus on the prediction of US car accident severity using the Decision Tree, Random Forest, K-Nearest Neighbors, Logistic Regression, and two popular tree-based ensemble methods, XGBoost and LightGBM. In the process, we first try PCA and then perform Grid-search and Cross-validation to tune the parameters. In order to solve the spatial heterogeneity and imbalanced data problems, we conduct the analysis of the whole United States and New York City with the resampling method. We finally make some comparations about methods and models we used to find a better way to predict the US car severity.
