What is Deep Learning is and how it works

Artificial intelligence is revolutionizing at a speed of vertigo and has brought about the interest of big companies thanks to its promising advances, many already a reality. It is, in fact, the so-called theme of Deep Learning, a technology of learning and classification based on networks of numerical artificial neurons. But it was not always like this. The success has come to Deep Learning after a long journey in the desert. While the current enthusiasm atmosphere may make us believe in impossible, a problem that experts warn like Yann LeCun, the truth is that this technology is still a big question in many aspects. Likewise, Deep Learning raises questions about the possible danger of its evolution.
