  3. Special Rule for Today • Everyone Who Turned in a Homework Participates

  4. Let’s go back to the list of features from the last class • As I read features off • If you used this feature (or something very similar), raise your hand

  5. For the features someone used • Did it end up in your final model? • Does this match the class’s overall intuition?

  6. List other features • I’d like everyone who turned in Assignment 4 • To tell me all of your other features that ended up in final models

  7. We now have… • We now have a list of features that ended up being used in models

  8. So let’s… • Go through how several of them were created • Actually do it… Re-create it in real-time, or show us your code… • Everyone who turned in the homework will show the class at least one feature • No one can show a second feature until everyone has had a chance to show at least one

  9. Comments? Questions?

  10. What tools were used? • Did anyone use any additional tools? • How else could you have created features?

  11. Now let’s… • Make a supermodel!

  12. Comments or Questions • About Assignment 5?

  13. Final Thoughts?

  14. If you enjoyed today’s class… • At some point in the next 2 years, we’ll be offering a Feature Engineering Design Studio course…

  15. Next Class • Monday, March 4 • Automated Feature Creation and Selection • Assignment Due: None

  16. Excel • Plan is to go as far as we can by 5pm • We will continue after next class session • Vote on which topics you most want to hear about
