For all the talk of artificial intelligence becoming increasingly brain-like, there’s one area where it frequently falls short: memory. Neural networks usually have to learn everything they need to know about their duties, rather than building on top of existing experiences like real brains do. Alphabet’s DeepMind team hopes to fix that. They’ve crafted an algorithm that lets a neural network ‘remember’ past knowledge and learn more effectively. The approach is similar to how your own mind works, and might even provide insights into the functioning of human minds.
