AI often exceeds what human beings can do, but it’s often only able to master one specific task extremely well. When AI tries to multitask, it has a tendency to abruptly override previously learned information in a phenomenon known as catastrophic forgetting. Researchers have found that using offline periods that mimic biological sleep in humans allows artificial neural networks to get better at learning, and avoid forgetting. For around eight hours each night – roughly a third of our lives in total – we exist in a state of unconsciousness paralysis. Our heartrate and breathing slow, our body temperature falls, and we lie immobile and unresponsive. But as we slowly progress through the stages of sleep something strange begins to happen: our brain activity shoots back up to levels similar to when we’re awake. Unbeknownst to us, as we drift off, our brains are spontaneously reactivating all that we’ve experienced in our waking states.[related id=2202…
