Therefore, the lower the MAE, the less error in your model. Mean Squared Error (MSE) n = number of points, y = actual point, y_hat = predicted point The MSE is the sum of the squares of all errors divided by the number of points.

The mean absolute error and the mean squared error are two common measures to evaluate the performance of regression problems. There are a number of key differences betwee the two: 1. Unlike the mean squared error (MSE), the MAE calculates the error on the same scale as the data. This means it’s … See more The mean absolute error measures the average differences between predicted values and actual values. The formula for the mean absolute error is: In calculating … See more Interpreting the MAE can be easier than interpreting the MSE. Say that you have a MAE of 10.
