Mean Squared Error
Type: Concept
As of November 2026, Mean Squared Error has been mentioned in 3 episodes across 2 podcasts, first heard Oct 2018 on Real Engineering. Mean square error is highlighted as a common loss function for regression tasks, measuring the average squared difference between predicted and actual values.
In statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator measures the average of the squares of the errors—that is, the average squared difference between the estimated values and the true value. MSE is a risk function, corresponding to the expected value of the squared error loss. The fact that MSE is almost always strictly positive is because of randomness or because the estimator does not account for information that could produce a more accurate estimate.
