Can you keep a secret?

摘要

Ever had an in-joke only you and your best friend knew the punchline to? According to computer scientists, artificial brains could use this kind of secret knowledge to deliver coded messages. Neural networks are computer systems designed to mimic the brain. Just as the brain's nerve cells are wired together in a complex mesh, neural nets consist of a web of electrical switches, or a computer simulation of these connections. When neural networks tackle a problem, connections that are ultimately successful become stronger than those that give a wrong answer. The more lessons a network trains with, the better it learns which pathways to follow to find the right answers.
