Total Error Equals Bias Plus Variance for Mean Squared Error
When mean squared error is the error metric, bias and variance can be specified with formulas, and Total Error = Bias + Variance can be proven. For deciding how to make progress on an ML problem, the informal bias and variance definitions used here are sufficient.
