How does the Root Mean Squared Error (RMSE) differ from Mean Squared Error (MSE)?
- RMSE is half of MSE
- RMSE is the square of MSE
- RMSE is the square root of MSE
- RMSE is the sum of MSE
The Root Mean Squared Error (RMSE) is the square root of the Mean Squared Error (MSE). While MSE measures the average squared differences, RMSE provides a value in the same unit as the original data. This makes RMSE more interpretable and commonly used when comparing model performance.
