Releasing fish for the future

Math that powers spam filters used to understand how brain learns to move our muscles

brain uses what it already knows to “predict” or “believe” that something new will happen, then uses that information to help make it so. “We used the idea that prior experience and belief affect the probability of future outcomes, such as taking ...
