What is it?
"Deep Learning is a new area of Machine Learning research, which has been introduced with the objective of moving Machine Learning closer to one of its original goals: Artificial Intelligence." [1]
What does that mean?
"Teaching machines to think has been a dream/nightmare of scientists for a long time. Rather than teaching a machine explicitly, Deep Learning uses simpler, core ideas and then builds upon them — much as a baby learns sounds, then words, then sentences." [2]
So just another technology?
May be not. MIT technology review ranked it amongst top 10 breakthrough technologies of 2013 which is going to change things forever. [3]
