Teaching signals for recurrent networks
• We can specify targets in
several ways:
– Specify the final activities
of all the units
– Specify the activities of all
units for the last few steps
• Good for learning attractors
• It is easy to add in extra
error derivatives as we
backpropagate.
– Specify the activity of a
subset of the units.
• The other units are “hidden”
