An education company named X Education sells online courses to industry professionals. On any given day, many professionals who are interested in the courses land on their website and browse for courses.

AUCC (Python Implementation)

ROC Tool is a tool that allows the user to visualize ROC curves and easily perform more advanced analysis on them. Specifically, the tool allows users to plot multiple ROC curves and their Regions of Interest, compute AUC and RRA, and plot multiple iso-PM curves.

Knowledge Discovery in Dataset

Machine learning for credit card default. Precision-recalls are calculated due to imbalanced data. Confusion matrices and test statistics are compared with each other based on Logit over and under-sampling methods, decision tree, SVM, ensemble learning using Random Forest, Ada Boost and Gradient Boosting. Easy Ensemble AdaBoost classifier appears to be the model of best fit for the given data.
