This method uses statistical means to find units that don't contribute
to the net's behavior. The net is subdivided into its layers, the
output of each neuron is observed for the whole pattern set and units
are removed that
- don't vary their output,
- always show the same output as another unit of the same layer or
- always show the opposite output of another unit of the same
layer.
This function is the first part of the method introduced by
[JS91]. For further information about the implementation
read [Bie94].
