It is only meaningful if std:: numericlimits < T >:: isinteger false. 1 Answer Sorted by: 8 In SGD, if you use epsiloninsensitive with epsilon0 it should work as if you used MAE. 
$e = y - \hat y = X\beta + \epsilon - X(X'X)^$. Returns the machine epsilon, that is, the difference between 1.0 and the next value representable by the floating-point type T. In fact, these two numbers are not equal, a is twice as much as b. Polytool is a Unity package that helps you with optimizing your models, right inside UnityIt makes optimizing models quite simple for those who value a quick and easy solution. If the model is correct, then they may sometimes be a fairly good estimate. The normal operation should be fabs (a - b) < DBLEPSILON, but when a pow (2, -100), b pow (2, -101), the result of the comparison is true because the result of (a - b) is 3.9443e-31, less then DBLEPSILON 2.22045e-16. Here are the most common ways to calculate experimental error: Error Formula In general, error is the difference between an accepted or theoretical value and an experimental value. Certainly the residuals are some sort of estimators of $\epsilon$ (to be clear, the definition of the residual is the estimator, the observed residual is an estimate).
