Liebe alle

Wir machen ein Wrap Up des ML-Kurses von Heute. Wer sich bis dahin das Material ansehen
möchte, ist auch herzlich willkommen.

Freitag 3.4., 10 Uhr.
e-Meeting: gleiches Teams-Meeting (siehe unten).
Chat ist auch bis dahin offen.

Programm:
* Fragen zur Vorlesung
* Besprechung der Übungen
* Wenn gewünscht, R-Code Schritt für Schritt
* Besprechung erste Resultate eigene Daten (sofern vorhanden)

Liebe Grüsse

Dear all

Everything is canceled nowadays. This is not the case for the scheduled machine learning
course!

It takes just a different format.

Please join in as you like!
On the Doodle list were 20 people, so I might not be all alone in front of a screen.

Happy home office + take care
Madlene

[1] Video Call and Chat

Please link into this Teams session (you click the link already now and hang up directly).
I will be on video call the given hours, on chat during whole Friday and respond on the
chat conversation sporadically before Friday (for e.g. installation problems).

MSTeams-Knigge:
* Please don't be shy to use the chat during the whole day!
* Please indicate in the chat that you have a question during the video conference, then I
can easily moderate.

Go to a web browser and paste the link:

[2] Installation:

You need R and an Editor, e.g. RStudio

R e.g. for Windows (the version of the software center is very old):
https://cran.r-project.org/ > Download R for Windows > base > Download R 3.6.3 for Windows

Rstudio:
https://rstudio.com/products/rstudio/download/#download

Following packages, run R code:
install.packages(c("grpgreg", "glmnet", "kernlab", "caret", "randomForest", "mboost",
                   "gbm", "geoGAM", "raster", "quantregForest"))
