I'll add my thoughts on the topic of "how do you know when you're out of the danger zone and can start marketing yourself as a machine learning expert?" Do competitions on kaggle (or find them on other sites, but kaggle is definitely the best place to start). Once you get past the point where you are finishing in the middle of the pack (multiple top 10% or 25% finishes and maybe a prize win) then you are an expert. That is proof that you are separate from than hackers who just throw scikit-learn algorithms at a matrix. The people in the master tier use clever feature engineering and/or code up custom learning algorithms to get themselves above the masses. Looking at a problem and figuring out the correct modeling approach is what the experts do. They don't just create a data frame and run down the list of classification algorithms that they have access to. Read the "No Free Hunch" reports on how the winners did it and you'll quickly see the difference between yourself and the experts.
