I love motivational examples in teaching complex ideas! I use this simple little video to teach Deep Learning to my students.
When we consider Deep Learning, we think of ideas like teaching a computer to recognize images of cats using Deep Learning OR training a computer to play pacman using Deep Learning. They all work in the same way. You let the Deep Learning system iterate with many examples and in each case, you tell the computer using a classifier if its interpretation was correct or not (aka is it a cat or not, Pacman scores, etc.)
That's Deep Learning for you!
