Q. Which metric is used to evaluate regression models?
A.
F1 Score
B.
Mean Absolute Error
C.
Precision
D.
Recall
Solution
Mean Absolute Error (MAE) measures the average magnitude of errors in a set of predictions, without considering their direction, making it a common metric for regression.
Q. Which metric is used to evaluate the performance of a model in terms of its ability to distinguish between classes?
A.
Confusion Matrix
B.
Mean Squared Error
C.
R-squared
D.
Log Loss
Solution
Log Loss measures the performance of a classification model whose output is a probability value between 0 and 1, evaluating its ability to distinguish between classes.
Q. Which metric would be most appropriate for evaluating a regression model?
A.
Accuracy
B.
F1 Score
C.
Mean Absolute Error
D.
Confusion Matrix
Solution
Mean Absolute Error (MAE) is a common metric for evaluating regression models, measuring the average magnitude of errors in a set of predictions without considering their direction.
