To whom it may concern, here are my solutions for the first exercise sheet. Best regards Janos Meny 2018-04-11 18:20 GMT+02:00 Bastian Bohn <bohn@ins.uni-bonn.de>:

Dear students of the P4E1 machine learning lab,

here is the announced mail regarding certain organizational informations:

1) To contact us, please always use the mllab@ins.uni-bonn.de email-address. This is also the address to send your solutions of the exercise sheets to.

2) Since the INS Website is being renewed and we are trying out the new system, the actual website of the practical lab (where you can actually find the exercise sheets and the supplementary stuff and so on) is: https://beta.ins.uni-bonn.de/teachings/ss-2018-207-p4e1-practical-lab-nu/

3) The "helpdesk" time slot, where Lisa, Jannik and I can help you with any programming troubles is Mondays between 3 and 5 p.m. in the Practical Lab room (6.012, Wegelerstr. 6). This will also be the time slot in which we will schedule individual group discussions after an exercise sheet has been due.

4) I assigned everybody to a working group. People who could not attend the first meeting have been assigned randomly. If there is anything wrong, please contact us or tell us next Wednesday. Note that there also might be some changes/reassignments within the upcoming weeks due to some people deciding not to attend the practical lab. So far, the working groups are:

Group A: Roman Wilhelm and Kin Tung Jonathan Chan Group B: Simon Thomä and Lara Fuhrmann Group C: Konrad Keßler and Kevin Weigl Group D: Janis Kemper and Lukas Erlenbach Group E: Justus Fink and Adolfo Camacho Melo and Milos Tepavcevic Group F: Leo Graf and Yuzhou Zhang Group G: Janos Meny and Alexandros Gilch Group H: Olmo Chiara Llanos and Tobias Muldee Group I: Jerónimo García and Juleana Villegas

Since the number of participants is odd and since Adolfo has already taken the P4E1 module before - and probably can't formally do it again (we're going to check this), nominally there are three people in group E right now. However, as I said, the groups might still change a bit during the next three weeks.

If you know that you won't attend the practical lab anymore, please tell us, so we can make the necessary adjustments as soon as possible.

5) As mentioned in the lecture: You will have to formally register for the P4E1 module in basis yourself. Note that you have to do this until the end of April! Note also that you cannot unregister once you registered!

6) How to get your jupyter-notebook running (in Linux - you will need python3 to be already installed): As shown today, the (probably) easiest way is to open a console and create a virtual environment:

virtualenv -p python3 NameOfYourEnivornment

Once created you can always activate the environment by running

source NameOfYourEnivornment/bin/activate

Then, to install the necessary packages for python you run

pip3 install -r requirements.txt

where you can find the requirements.txt file on the website. Finally, you can run and edit your jupyter-notebooks via

jupyter-notebook NameOfYourNotebook.ipynb

7) Exercise sheet 1 can be found on the website and is due on May 1st. Good luck and have fun exploring!

Best regards, Bastian Bohn
