Decoding the Brain Goes Global With the International Brain Initiative
Few times in history has mankind ever united to solve a single goal. Even the ultimate moonshot in history—putting a man on the moon—was driven by international competition rather than unification.
So it’s perhaps fitting...
The Brain Predicts Reward Like an AI, Says New DeepMind Research
The idea of reinforcement learning—or learning based on reward—has been around for so long it’s easy to forget we don’t really know how it works.
If DeepMind’s new bombshell paper in Nature is any indication,...
