Which metric is commonly used to evaluate the performance of a classification model?
Directions : Evaluation metrics help measure the effectiveness of a model's predictions.
Q. 7 of Quiz-2121 (Que-ID : 4723)Which metric is commonly used to evaluate the performance of a classification model?
- Mean Squared Error (MSE)

- Adjusted R-squared
Ans → (C)
Explanation → The F1 Score is commonly used for evaluating classification models, especially when dealing with imbalanced datasets, as it considers both precision and recall.
This question is taken from this post → A Quiz on Artificial Intelligence and Machine Learning - attemp/practice
