While you now know many of the intricacies of low-level GPU programming, you won't be able to apply this knowledge to machine learning immediately. If you don't have the basic skills in this field, like how to do a basic statistical analysis of a dataset, you really should stop and familiarize yourself with them. Stanford Professor Andrew Ng, the founder of Google Brain, provides many materials that are available for free on the web and on YouTube. Professor Ng's work is generally considered to be the gold standard of educational material on machine learning.
