AI Uses Artificial Sleep to Learn New Task without Forgetting the Last
Experiments demonstrated the importance of having “rapidly alternating sessions of training and sleep” while the AI was learning a second task.

Scientists at the University of California, San Diego (UCSD) and the Czech Republic's Czech Academy of Sciences taught an artificial intelligence (AI) to learn a second distinct task without overwriting connections learned from a first task, through the use of simulated sleep.
UCSD's Erik Delanois said it was critical to "have rapidly alternating sessions of training and sleep" while the AI was learning the second task, which consolidated links from the first task that would have otherwise been forgotten.
"Such a network will have the ability to combine consecutively learned knowledge in smart ways, and apply this learning to novel situations—just like animals and humans do," said the University of Massachusetts Amherst's Hava Siegelmann.
