Preliminary Training Output This section lists the objective function for each preliminary iteration run. The weights from the iteration number that has the smallest objective function are passed as input for final training. Because the target is continuous, the error function is set to normal. Therefore, the objective function that is being minimized is the least squares error. Iteration number 0 has the smallest objective function. The parameter estimates for iteration number 0 are also listed in this section of the output.
