"At <a href=""https://www.youtube.com/watch?v=Gfr50f6ZBvo&amp;t=15m05s"">15:05</a> when mentioning GPUs he says how "everything is a matrix multiplication".  What does he mean by this comment?",(reply>), Neural networks process data patterns by doing vector dot products (aka matrix multiplication) over and over and over … GPU hardware is particularly suited for these types of operations.<br>The idea behind this, imho, is that AI doesn’t “understand” what it does. It is just a machine for doing operations with matrices.
