How Deep Learning works?
Unlike Artificial Intelligence (AI) or Machine Learning (ML), Deep Learning (DL) is a relatively new term circa 2010. However the underlying technology is not new. Deep Learning is based on Artificial Neural Networks (ANN). Artificial Neural Networks are as old as AI itself. The original idea behind AI was to make computers as smart as human brain. And that's what ANN tries to do by mimicking the brain. The recent hype around DL, especially since 2010, is because the idea seems close to its actual fruition. This dream like scenario is made possible by two recent technological breakthroughs i.e. GPUs and Big Data.
