00:07:44 Fran Barton: Hi!!!
00:08:00 Mei Ling Soh: Hello!
00:08:17 BEN: Hello!
00:08:53 Kim Martin: Hello :)
00:09:15 Stijn Van de Vondel: Hiya!
00:09:31 Ryan S: 18 participants before kick off time! Jon, hope you're expecting a large crowd. :-)
00:11:18 Fran Barton: Gesundheit
00:11:49 Jyoti Bhogal: That's Starry Nights in the background @Jon :)
00:11:59 Kim Martin: I'm going to turn off my camera and mic for a little bit so no one is subjected to seeing me eat peanut butter from the 'emergency snack jar' 😵
00:12:08 Fran Barton: :-D
00:12:31 Fran Barton: I'm in a shared office with background noise so will stay on mute most of the time
00:12:43 Stijn Van de Vondel: Gotta say, that's one hell of a silent vacuum
00:13:05 Stijn Van de Vondel: If it's not the mic, you may be sitting on a vacuum goldmine
00:13:21 Kim Martin: 😂
00:16:42 Kim Martin: Shall we do tag-team presentations to spread the responsibility/opportunity around?
00:16:51 Kim Martin: (swopping presenter mid-session/chapter)
00:17:18 Raymond Balise: chapter 2 is a lot
00:20:02 Ryan S: love that idea -- discussion one week, exercises second week
00:20:15 Mei Ling Soh: I second that
00:20:27 Kim Martin: +1
00:20:40 Raymond Balise: thoughts on Tidymodels vs Base?
00:22:25 Kim Martin: Nothing against Tidyverse (recent convert), but it makes sense to me to start with base
00:22:36 Jyoti Bhogal: The link for today's meeting, I got through a friend. What do I need to do to subscribe for receiving the links for meetings?
00:22:41 Kim Martin: (the argument is overblown, imo)
00:23:16 Jyoti Bhogal: thank you
00:23:17 Raymond Balise: 👍🏼
00:23:17 Kim Martin: https://github.com/r4ds/bookclub-islr
00:23:23 David Severski: To be clear, we’re talking tidymodels vs base, not tidyverse v base.
00:23:31 Jon Harmon (jonthegeek): r4ds.io/islr
00:28:03 Fran Barton (he/him): do we know why they are called "supervised" and "unsupervised"? interesting terminology and I think it would help me to understad better if I could grasp what they have to do with whether you're looking for outputs or not
00:28:35 August: supervised has a target/output to be predicted.
00:29:02 Fran Barton (he/him): "letting the machine go play" is great - that helps thx
00:29:15 Kim Martin: All models that involve 'training' are supervised, I'm guessing?
00:30:24 Kim Martin: If the process of the unsupervised model 'deciding' on how to group things into clusters is computationally expensive, then you'd train it first...
00:30:52 Kim Martin: … then after it has 'decided', it'll be quick in the future to slot new observations into those clusters
00:30:58 Kim Martin: (guessing)
00:31:44 BEN: tidymodels nomenclature is always exciting :3
00:32:05 Arnab Dey (he/him): epsilon?
00:32:12 Kim Martin: 'Exciting'? (novice - curious)
00:32:35 BEN: both
00:32:36 Keuntae Kim: that stands for "element of"
00:32:50 SriRam: In set theory, it is called “belongs to”
00:32:51 Arnab Dey (he/him): ah!
00:32:52 Kaustav Sen: belongs to? https://www.mathdoubts.com/belongs-to/#:~:text=In%20the%20set%20theory%2C%20the,element%20belongs%20to%20the%20set.&text=It%20helps%20us%20to%20express,its%20set%20in%20mathematical%20form.
00:32:53 August: Isn't E also euler?
00:32:57 Keuntae Kim: correct. already in the slide... hahah
00:33:08 Raymond Balise: add the link to that book later plz
00:33:14 Fran Barton (he/him): wikipedia: "The lunate epsilon, ϵ, is not to be confused with the set membership symbol ∈"
00:33:33 Kim Martin: Math notation as bird spotting hobby alternative...
00:33:42 August: sorry you're right euler is more like e
00:34:05 Ryan Metcalf: Latex: \in
00:34:18 Jon Harmon (jonthegeek): r4ds.io/islr
00:34:21 Jon Harmon (jonthegeek): statlearning.com
00:34:23 Raymond Balise: the notation book reference plz
00:34:29 Kim Martin: https://www.amazon.com/Mathematical-Notation-Guide-Engineers-Scientists/dp/1466230525
00:34:37 Raymond Balise: thx kim
00:34:41 Mei Ling Soh: https://www.rapidtables.com/math/symbols/Basic_Math_Symbols.html
00:35:11 Fran Barton (he/him): ^ useful! thx
00:38:08 Fran Barton (he/him): I think `install.github("ISLR2")` is maybe missing the repo owner name "CRAN/ISLR2" ??
00:38:37 Ryan S: let's say it's been many years since my last "traditional / undergrad" stats class. Will I survive ISLR or should I brush up a bit?
00:39:06 Fran Barton (he/him): ah of course - let's fix on github ;-)
00:39:56 SriRam: This is also my stepping stone into this world
00:40:25 Ryan S: good to know. Otherwise, I have the hours of 2:00 AM to 3:00 AM on Saturdays I can use to review Stats 101.
00:40:30 Ryan S: 😆
00:43:16 Ryan S: thx!
00:43:19 Wayne Defreitas: thx
00:43:19 Stijn Van de Vondel: Thanks for hosting, can't wait for the next parts!
00:43:20 A. S. Ghatpande: thanks
00:43:23 Jiwan Heo: thank you!1.12.2 Cohort 2

00:08:45 Fariborz Soroush: Lighting in my room is terrible. I cut my video :D
00:10:23 Mei Ling Soh: That’s fine!
00:15:24 Fariborz Soroush: Go CHoPpers I guess?:lol:
00:15:36 Rose Hartman (she/her): Woot 🙂
00:19:30 Amber: My wifi is a bit rocky so I don’t want to put on my audio, but hi everyone! I’m Amber, I’m a student at CUNY Grad Center in NY where I’m studying Quantitative Methods in the Social Sciences, and have struggled with r during the entire time of my studies 😂 so I’m really looking forward to this book club to finally get comfortable with r
00:19:59 Rose Hartman (she/her): Hi Amber! 🙂
00:20:36 Rose Franzen (she/her): Hi Amber!
00:20:38 Nilay Yönet: 👋☺️
00:20:40 Fariborz Soroush: Hi Amber :)
00:21:46 Mounika [Monika]: Hi Amber :)
00:25:15 Mounika [Monika]: Mei, could you please post also the link to the R4DS GitHub resource?
00:25:24 Rose Franzen (she/her): https://r4ds.github.io/bookclub-islr/book-club-meetings.html
00:25:34 Mounika [Monika]: Thank you !
00:36:28 Rose Hartman (she/her): Did you get the capitals? install.packages(“ISLR2”)?
00:36:31 Rose Hartman (she/her): It worked fine for me
00:36:38 Rahul: I don’t know much R but looking online https://cran.rstudio.com/web/packages/ISLR2/ seems that it Depends: R (≥ 3.5.0)
00:37:38 Nilay Yönet: yes my R version is
00:37:40 Nilay Yönet: R version 4.1.0 (2021-05-18)
00:38:12 Rahul: OK, then that might not be the reason
00:38:43 Nilay Yönet: Idk :/ I will try cloning :)
00:38:45 Rose Hartman (she/her): Nilay, usually when I get that error message, I find it’s because I had a typo in the package name ;) Double check that you typed it in correctly?
00:39:03 Nilay Yönet: oh ok I will check that as well :)
00:49:10 Fariborz Soroush: Suggestions for API? VSCode? Jupyter? I remember R had its own interpreter but I have MacOS not sure if it works there.
00:50:10 Rose Hartman (she/her): I really like RStudio for R: https://www.rstudio.com/products/rstudio/
00:50:24 Mounika [Monika]: RStudio is the OG for R!!
00:50:38 Fariborz Soroush: Ok, RStudio it is :) :D
00:54:31 Rahul: 13th march
00:54:36 Rose Hartman (she/her): Quick poll: Who is interested in doing tidymodels? I am, but happy to skip it if everyone else would prefer to stay in base R.
00:55:35 Mounika [Monika]: I think the plan of covering base as well as tidyR sounds good.. I am ok sticking to baseR if both is too much
00:57:24 Amber: ^^ same
00:57:44 Rose Franzen (she/her): I am also interested in tidy models
00:57:47 Amber: Bye everyone!1.12.4 Cohort 4
