Hey folks, today we'll be predicting Titanic survival using a random forest classifier. We'll get more into what a random forest classifier is in a little bit when we get to it, but first we're going to be dealing a lot with the Titanic dataset. This is an iconic dataset used for machine learning practice, and today we're going to be working particularly with the Titanic dataset version from Kaggle.
We'll even be towards the end submitting our data in the Kaggle competition for the Titanic dataset. So, fun video, fun set of videos, let's get started with it. All right, first we're going to import all of our grade items, set everything up with Google Drive, set our base URL, and import our random forest classifier, which we'll use to create a random forest classifier model.
And we'll also be using label encoder, which is a way we'll walk through to make zeros and ones out of our values, similar to the one-hot encoding that we did in a previous set. Okay. Let's load our data from this CSV file, which, again, is provided by Kaggle.
So, I'm going to call it Titanic data, and it's going to be what we get when we get a CSV file, when we read a CSV file and turn it into a data frame. So, we'll be working with this data frame a lot. And it's going to be at the base URL and the CSV URL up above.
And we should be able to see our Titanic data here. And here it is. We'll start walking through that data in the next bit.
