How do you know if your machine learning model is actually making accurate predictions, or just guessing? Welcome to the ultimate guide to evaluation metrics. In this video, we break down complex data concepts into plain English. You will learn exactly how to measure and score models using simple metrics like R-squared, Residual Analysis, the Confusion Matrix, and ROC-AUC curves. We also look at how to handle real-world challenges like class imbalance, giving you the exact tools you need to build reliable AI models.
