The Extend Learning facility is used to fill any gaps in the range of training examples or to extend the range. The Input/Output values of the copied examples can be modified by Jitter (a small random number). Three levels of Jitter are available. Contract within range: The Jitter moves the values towards the range average. Expand out of range: The Jitter moves the values away from the range average. The values are not limited by the range. Retain current range: Copied examples that would result in a change of range are deleted.
Enter the number of extra example rows to produce by copying and jittering.
