Let's take a look at the Kaggle contest and go through a tutorial!
The plan is to go through the Titanic tutorial, which will introduce us to Kaggle, training models in general, and building Random Forrest model specifically. The tutorial is a zero-install, using a web-based notebook for writing code -- so you should bring a laptop with a browser at least.
An advanced approach would be to get this working locally instead of in a web-notebook. That'd require a local Python installation and some libraries.
In general we'll customize this walk-through depending on the active attendees, with the goal of striking a good balance between overview of what's going on and a deep-dive on details.
