It was as though we were giving the neural networks the equivalent of a good, long nap. Sleeplike states in neural networks are very different from the mode your PC enters after some set period of inactivity. We are just starting to investigate an additional benefit of artificial sleep in our simulations. We have found that applying artificial sleep states seems to reset idle neurons to ensure they become functioning components in the network. Similarly, we expect that sophisticated AI systems will help us to more fully understand sleep and other characteristics in biological systems.
