Model Selection: ROC Curves, Regression Evaluation, Conclusion

This lecture covers the concept of thresholding in binary decision-making, the Receiver Operating Characteristic (ROC) curve, precision-recall curves, mean squared error, root mean squared error, root mean squared error log, coefficient of determination, naive methods for regression and classification, model selection, and the importance of evaluating models on unseen data. The instructor concludes by highlighting the need for further exploration in machine learning techniques.
