🎃 In this video, presented by Bea Stollnitz, a Principal Cloud Advocate at Microsoft, we'll dive into categorical features, understand what they are, when to use them, and how to create them to improve the performance of our regression models. We'll continue to work with the pumpkin dataset, which we've used in our previous videos, as we try to find the cheapest month to buy pumpkins. In this video, you'll learn: ✅ The importance of categorical features in predictions ✅ How to create categorical features using pandas 🐼 ✅ One hot encodings 🔥 ✅ Improving regression results with additional features Make sure to subscribe and hit the notification bell 🔔 so you won't miss our next set of videos, where we'll look at logistic regression. See you there! 0:00 - Intro 0:33 - Recap of the code run in previous video 0:50 - Can we improve our results with more features? 1:16 - Pumpkin varieties as strings don't work for regression 1:32 - Can we repla …...more
