Since many of you got the last question incorrect, let's understand Confusion Matrix in detail A Confusion Matrix is used to evaluate how well a classification model performs by comparing actual vs predicted outcomes. 🔍 Structure: • Actual Positive, Predicted Positive → ✅ True Positive (TP) • Actual Positive, Predicted Negative → ❌ False Negative (FN) • Actual Negative, Predicted Positive → ❌ False Positive (FP) • Actual Negative, Predicted Negative → ✅ True Negative (TN) 📘 Key Terms: • TP: Predicted Positive & Actually Positive • TN: Predicted Negative & Actually Negative • FP: Predicted Positive but Actually Negative • FN: Predicted Negative but Actually Positive 🧮 Formulas: • ×Accuracy× = (TP + TN) / Total • ×Precision× = TP / (TP + FP) • ×Recall× = TP / (TP + FN) • ×F1 Score× = 2 × (Precision × Recall) / (Precision + Recall) 💡 Analogy: Spam Email Detector • TP: Spam email marked as spam • TN: Real email marked as not spam • FP: Real email marked as spam • FN: Spam email marked as real 💬 React with ❤️ for more such tutorials!
