Forgetfulness is a major flaw in artificial intelligence, but researchers have just had a breakthrough in getting 'thinking' computer systems to remember.

Taking inspiration from neuroscience-based theories, Google’s DeepMind researchers have developed an AI that learns like a human.

Deep neural networks, computer systems modelled on the human brain and nervous system, forget skills and knowledge they have learnt in the past when presented with a new task, known as ‘catastrophic forgetting’.
