Regression Metrics

MSE (Mean Squared Error)

Measures the average squared difference between predicted and actual values, penalizing larger errors:

MSE=1N∑i=1N(yi−y^i)2MSE = \frac{1}{N} \sum_{i=1}^N (y_i - \hat{y}_i)^2

MAE (Mean Absolute Error)

Measures the average absolute difference between predicted and actual values, reflecting the magnitude of errors:

MAE=1N∑i=1N∣yi−y^i∣MAE = \frac{1}{N} \sum_{i=1}^N |y_i - \hat{y}_i|

RMSE (Root Mean Squared Error)

Represents the square root of MSE, interpretable in the same units as the target variable, highlighting larger errors:

RMSE=MSE=1N∑i=1N(yi−y^i)2RMSE = \sqrt{MSE} = \sqrt{\frac{1}{N} \sum_{i=1}^N (y_i - \hat{y}_i)^2}
