The estimated time for a Boltzmann Brain to appear in the dead vacuum of space from random spontaneous entropy decrease is on the order of 10^10^50 years[0]. No time at all, compared to infinity.

His Neural Networks for Machine Learning course¹ is quite a pleasant journey going into everything from simple perceptrons to RBMs, and DBNs² and their uses. As a bonus he's got a quirky sort of dry humour that kept things interesting.
