Evaluating Model Performance
Evaluating the performance of a machine learning model is crucial to ensure its effectiveness. We use metrics like accuracy, precision, recall, and F1 score for classification problems.

2
Accuracy
Accuracy measures the ratio of correctly predicted instances to the total number of instances:
Accuracy = (True Positives + True Negatives) / Total Instances
While useful, accuracy alone might not be sufficient for imbalanced datasets.
