Vs (MSE & RMSE)
Description
MSE (Mean Squared Error) and RMSE (Root Mean Squared Error) are both used to measure the accuracy of a model's predictions, with a focus on regression tasks.
- MSE quantifies the average squared difference between predicted and actual values. The larger the MSE, the worse the model's performance.
- RMSE is simply the square root of MSE, bringing the error back to the same unit scale as the original data, making it more interpretable.
Differences
- MSE emphasizes larger errors more due to the squaring of the differences. It can be sensitive to outliers.
- RMSE provides a more tangible error metric as it's in the same units as the target variable.
Use Cases
- Use MSE when you want to penalize larger errors more heavily.
- Use RMSE when you want a metric that is in the same units as the target for easier interpretation.
