WebJul 5, 2024 · There is no correct value for MSE. Simply put, the lower the value the better and 0 means the model is perfect. Since there is no correct answer, the MSE’s basic value is in selecting one prediction model over another. Similarly, there is also no correct answer as to what R2 should be. 100% means perfect correlation.

WebJan 19, 2024 · MSE can be preceded by the sigmoid function, which outputs a number p ∈ [ 0, 1], which can be interpreted as the probability of the input belonging to one of the classes, so the probability of the input belonging to the other class is 1 − p.
