Data science and machine learning are rapidly growing fields that focus on extracting insights from data. But what actually hides behind the buzz words? In this talk I'll use data science tools in F# to analyze some publicly available online data. You'll see how F# simplifies data processing tasks and seamlessly integrates different steps of the analysis. I'll also explain cool ideas behind some machine learning algorithms, such as deep neural networks. You'll see how easy it is to dive into data with the right tools and how to extract interesting information yourself.
