Pushing Mathematical Limits,a Neural Network Learns Fluid Flow

摘要

Drop a pebble into a flowing stream of water.It may not change the pattern of flow very much.But if you drop a pebble into a different place,it may change a lot.Who can predict?Answer:A neural network can.A group of computer scientists and mathematicians at the California Institute of Technology(Caltech)in Pasadena,CA,USA,has opened up a new arena for artificial intelligence(AI),by showing that a neural network can teach itself how to solve a broad class of fluid flow problems,much more rapidly and more accurately than any previous computer program[1].
