WebLong answer: the ideal MSE isn't 0, since then you would have a model that perfectly predicts your training data, but which is very unlikely to perfectly predict any other data. What you want is... WebSquaring the differences serves several purposes. Squaring the differences eliminates negative values for the differences and ensures that the mean squared error is always greater than or equal to zero. It is almost always a positive value.
