Recurrent networks learn to tell time

Chaotic networks produce rich temporal dynamics that could be useful for timing, but are extremely sensitive to perturbations. Work now shows that a learning rule for the weights of a chaotic recurrent network can stabilize time-varying activity patterns. This result can be used to train output units to produce generic timed responses.
