Geolocation of Twitter Users with Machine Learning Report Abstract This project is to train a classifier to predict the tweets’ location based only on its content. 1. Introduction Aside from features selected from project1, I also add the time stamp of tweet as a feature. And select three models(Logistic regression, SVM, Naïve Bayes) to train […]

3 Decision Trees Ever play the game 20 questions? That’s what a decision tree is — something which asks questions about an item until it can determine what label an item should have. Decision trees are the model produced by decision tree algorithms, and decision tree algorithms are classification algorithms. Decision trees divvy up the

Project Report Feature extraction I choose the two teams’ ELO rating and their ranks at the time when the match between them happened as my model’s feature. Because ELO reflects the relative skill levels of the two teams. Obviously the team with higher ELO is more likely to win. Indeed, a naïve model that simply
