What is the primary purpose of using Mean Absolute Error (MAE) to measure the quality of predictions?
What is the primary purpose of using Mean Absolute Error (MAE) to measure the quality of predictions?
- To provide a symmetric measure of error that penalizes negative errors more heavily
- To provide an intuitive interpretation of the error in terms of relative error
- To be robust to outliers in the training data
- To describe how big the average error is in the same unit as the input data (correct)
What is a potential drawback of using Mean Absolute Percentage Error (MAPE) to measure the quality of predictions?
What is a potential drawback of using Mean Absolute Percentage Error (MAPE) to measure the quality of predictions?
- MAPE is not robust to outliers in the training data
- MAPE can result in zero divisions or very large values when the actual values are small (correct)
- MAPE does not have the same unit as the input data, making it difficult to visualize
- MAPE does not provide an intuitive interpretation of the error
Which of the following is a key advantage of (Root) Mean Squared Error ((R)MSE) over other error metrics?
Which of the following is a key advantage of (Root) Mean Squared Error ((R)MSE) over other error metrics?
- (R)MSE penalizes negative errors more heavily than positive errors
