Data Science and Machine Learning (Theory and Projects) A to Z - Machine Learning Model Performance Metrics: The Confusi

The video tutorial introduces the concept of a confusion matrix, a tool used in classification to evaluate the performance of a model by showing how often actual classes are confused with predicted ones. It explains the significance of matrix entries, particularly the diagonal for accurate classifications and off-diagonal for misclassifications. The tutorial also covers precision and recall, two important performance measures, and discusses their differences from accuracy. Additionally, it highlights other performance metrics like ROC curves and AUC. Finally, the video aims to link classification models with probability distributions, setting the stage for further exploration in machine learning.

Define recall in the context of a confusion matrix.
