What is “deep learning”? How can we understand it?


“What is deep learning?” It is frequently asked because “deep learning” is one of the hottest topic across the industries. If you are not an expert of this field, I provide the answer from Andrew.Ng below, it is one of the best answer to the question.
“It’s a learning technology that works by loosely simulating the brain. Your brain and mine work by having massive amounts of neurons, jam-packed, talking to each other. And deep learning works by having a loose simulation of neurons — hundreds of thousands of millions of neurons — simulating the computer, talking to each other.”(1)
Yes, it is right. So “deep learning” is explained by comparison with brains. But there is a problem, Do you understand how your brain works? It is very difficult as we can not see it directly and there are no movements in our brain. Electronic signals are just exchanged so frequently. We cannot have clear picture about “how our brain works”. So It is the same as “deep learning”.
I should change my strategy. I would like to take purposes-oriented explanations, rather than technological one. “Deep learning” works for the purpose to understand how human being consider, feel and behave. When we sit down in front of the computers, they can see us, listen to us and understand what we want. “Deep learning” enables computers to do that. Therefore computers are not just calculators anymore. They start understanding us by the technology called “deep learning”.

Then we can understand the terms of computer science with ease.
Power to see the world : Computer vision
Power to read the text : Natural language processing (NLP)
Power to understand what you say : Speech recognition

Yes, these sound like human being. Although it is in an early stage, computers start understanding us slowly but steadily. But in case you are still curious on how it works, you can go to the world of math and programming. With math and programming, we can understand it more precisely. “TF club” is named after “TensorFlow”, which is one of famous libraries for “deep learning”. You can see the image of “TensorFlow” in this article. Hope you can go this journey with us!
