Evaluating ML Models Visually: Confusion Matrix, ROC, and PR Curves

by

In the world of machine learning, building a model is only half the battle. The other half lies in effectively evaluating its performance to ensure it meets your requirements and behaves as expected in real-world scenarios. While numerical metrics like accuracy and F1-score provide valuable insights, visual evaluation methods offer intuitive, comprehensive ways to understand … Read more

What Is a Good ROC AUC Score?

by

When evaluating a classification model, one of the most commonly used metrics is ROC AUC (Receiver Operating Characteristic – Area Under the Curve). This metric measures how well a model distinguishes between positive and negative classes. However, many data scientists and machine learning practitioners ask the question: What is a good ROC AUC score? In … Read more
