Bundesliga xG 15-16: [Blog&Code]
Description: Expected Goals is the hot metric in soccer analytics. Here I compare the actual results and those predicted by Expected Goals compare in Germany’s top soccer league, the Bundesliga.
Description: Identifying hate speech is an important task on the internet. I used scikit-learn and the nltk package to build a hate speech classifier using Twitter data from CrowdFlower and built an accompanying app. The final model utilized the Random Forest Classifier and achieved 76% accuracy on unseen data, a 26% increase over the baseline accuracy of 50%.
Description: Kickstarter is the foremost platform for crowd-sourced projects on the internet. I first scraped Kickstarter data and then used R’s caret to build a model that predicts whether or not a project will be funded. The final model was an ensemble of a Logistic Regression classifier built on numerical features and a Random Forest model built from text features. It achieved close to 83% accuracy on unseen data compared to a baseline of 60%. I am still working on this project to build an associated web app. This app will allow a user to input information on his/her project idea, calculate a probability of its being funded, and make recommendations to increase this probability.
