00:23:12 Jon Harmon (jonthegeek): @jim Which chapter are you going to present: 13? 14? 15? 😊
00:27:52 Jim Gruman: :) sure, 13 sounds good
00:29:42 Jon Harmon (jonthegeek): Woot!
00:29:57 Jordan Krogmann: 1, 1000, 5000 is the correct answer
00:31:11 Jon Harmon (jonthegeek): Ok, Jim! You're PRed into the README, no take-backsies!
00:33:44 Tan Ho: fixed sorry
00:35:29 Tony ElHabr: i'm sorry but are these python generated graphs?
00:35:33 Tony ElHabr: unforgiveable
00:36:06 Tan Ho: gg
00:36:12 Tan Ho: i'm out
00:36:54 Jon Harmon (jonthegeek): Ok, after Jim everyone who's here will have gone at least once! Except wait Tan never actually went did he?????
00:37:45 Tony ElHabr: CALL HIM OUT
00:38:03 Jon Harmon (jonthegeek): TAN WHAT CHAPTER ARE YOU PRESENTING??? 14, right?
00:39:01 Tan Ho: *awkwardly looking around after going MIA from the book club since chapter 9*
00:39:43 Tony ElHabr: as long as tan gives us a killer review at the end of this all, then i'll give him a pass
00:40:03 Jon Harmon (jonthegeek): Fair! Tan *is* the master of the review week!
00:40:21 Jon Harmon (jonthegeek): I pinged Max on the Slack to see if we should do a review after 14, or after 15, or later, or what.
00:40:55 Tony ElHabr: how can we do a proper review if we never stop learning?
00:41:14 Tan Ho: I might be more apt to do 15, I think?
00:41:23 Jon Harmon (jonthegeek): Yeah, this one is tricky 'cuz I'm not sure when it ends 🙃
00:41:53 Tony ElHabr: tan picks chapter 15 so he can have 3 weeks to prep :P
00:42:02 Tan Ho: two weeks to catch up and one week to prep!
00:42:21 Tan Ho: okay I lied twenty days to catch up and one day to prep, let's be honest
00:42:46 Tony ElHabr: 21 days to catch up cuz you're going to live code
00:42:51 Tan Ho: fair!
00:42:56 Tan Ho: that part don't scare me
00:54:23 Jordan Krogmann: Thanks andy!
00:54:23 Tan Ho: if 16 isn't written by the time I present we can probably just review lol12.14.2 Cohort 2

00:34:21 August: build your own engine]
00:34:40 August: that's what the link is sorry.
00:39:39 Amélie Gourdon-Kanhukamwe (she/they): Hear hear!

00:36:03 Federica : finalize() with {dial} take a parameter object and modify the unknown parts
00:44:40 Daniel Chen (TA), NYC: https://dials.tidymodels.org/
00:49:04 jiwan: i think you're muted, couldn't hear you
00:52:24 Federica : I was wondering about the regularization_factor()
00:54:21 jiwan: These parameters are auxiliary to random forest models that use the "ranger" engine. They correspond to tuning parameters that would be specified using set_engine("ranger", ...).
00:59:27 jiwan: dials::mtry()
# Randomly Selected Predictors (quantitative)
Range: [1, ?]
01:00:29 jiwan: regularization.factor = tune("reg")
01:00:42 jiwan: regularization.factor = tune()
