In machine learning, metrics are essential for evaluating model performance. Here's a guide to key metrics:
🎯 Accuracy
- Measures the ratio of correct predictions to total predictions.
- Formula: (True Positives + True Negatives) / (Total Predictions)
- Accuracy
🔍 Precision
- Focuses on the accuracy of positive predictions.
- Formula: True Positives / (True Positives + False Positives)
- Precision
📌 Recall
- Evaluates the model's ability to capture all positive instances.
- Formula: True Positives / (True Positives + False Negatives)
- Recall
🧩 F1 Score
- Balances Precision and Recall using harmonic mean.
- Formula: 2 * (Precision * Recall) / (Precision + Recall)
- F1_Score
📈 AUC-ROC Curve
- Represents the area under the Receiver Operating Characteristic curve.
- ROC_Curve
