It’s really quite simple, imagine in your head how people learn. Easy right. Now imagine a machine doing the same thing. Ok, got that?, no? That one is a little bit harder because in order to imagine a machine learning you would need to be able to imagine breaking a universal logical law that has existed since the dawn of consciousness in man, the law of contradiction. The term machine learning is in fact a logical contradiction, and if there were ever created a machine capable of doing it (learning), it would no longer be a machine. The term “deep” feels so important, so interesting, so meaningful, but in the actual real world it nothing more than a hedge modifier term which can mean whatever one wants it to mean, and sounds really cool at the same time. Deep learning is nothing more than a pseudo-concept based on a logical contradiction. To sum up deep learning is not learning, it is nothing more than a form of modern computing, powerful, yes, interesting, yes, useful, yep, learning, nope. This link might help some.
