How do babies learn? Trial and error. There was once a theory that the ability to walk, talk and were unlocked over time during a baby’s development. It is now known that babies try micro muscle movements and get feedback on what is working. They then string the micro movements together into patterns so that their mobility gets better and better.
How will machines learn in the future? Trial and error. The feedback loop. Machine learning does not give exact results, but rather allows the machine to provide the best guess, based on training data and feedback, as to what the result is. As demonstrated in this video, machines will learn how to walk using trial and error.
