WebHad to learn this the hard way myself. Was developing a linear regression model where i scaled the features to be 0-1, but didn't scale the labels. Labels were house prices so they were in the hundred thousand to million range and i ended up with MSE values of 4-40 trillion. I actually had to count the number of zeros to figure the exact value LOL. WebAug 10, 2024 · There is no MSE value which is considered ‘normal’ as it’s an absolute error score which is unique to that model and dataset.

In statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors—that is, the average squared difference between the estimated values and the actual 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 (and not zero) is because of randomness or because the e…
