Machine Learning is super cool, but what about those of us who maybe got a D in statistics (or maybe didn't bother taking the class). With modern systems, it's relatively simple to train a model regardless of your background, but how do you know if the model you've trained does the "right" thing and how do you actually use your model?
This talk will explore how to train models (using big data because that's what the presenter works with, but it will work just fine on small data as well...

Stripe processes billions of dollars in payments a year and uses machine learning to detect and stop fraudulent transactions. Like models used for ad and search ranking, Stripe's models don't just score—they dictate actions that directly change outcomes. High-scoring transactions are blocked before they can ever get refunded or disputed by the card holder. Deploying an initial model that successfully blocks a substantial amount of fraud is a great first step, but since your model is altering...
