Hi,

exam inspection is Wednesday April 10th. Below is a list with exact times and matriculation numbers. Location is the CoLi seminar room.

Please note, that it is an inspection only. There will be nobody to discuss. In case you find a grading mistake, you have to open a ticket by sending a mail to nntiws2324@lsv.uni-saarland.de . The ticket should explain in detail why you believe the grading of a specific question is wrong.

What does not count as a grading mistake:

* you think that deducing X points for Y is not justified. All exam questions where graded by one (sometimes two) people and there was a strong focus on consistency within a question.

* The question was on topic Z and asked for something very specific. You write something else on topic Z but did not give the answer. This does not count as partially correct.

* You mixed answers to different questions on the same sheet. Graders did not search for bits and pieces belonging to the question they were grading.

Best regards,

Dietrich Klakow

Hi all,

you can now submit the project in the CMS on your personal status page. Please include the repo containing your code as well as the .tex, .pdf and all image files for your report and and all image files you created if they are in separate files. You can just zip all of this into a single zip file. You do not need to include the stored embeddings, but it should be straight forward for us to reproduce them.

Making task 1 run on a laptop.

Written on 03.03.24 (last change on 03.03.24) by Michael Schott

Hi all,

since it has occurred multiple times now that teams ran notebooks on the submit node, we want to make sure this is not caused by the computational load required to solve task 1 exceeding your computational resources. Note that task 1 can be run without problems on a laptop with 8 GB of ram and possibly less. However, for this you have to disable the gradient computation, since otherwise PyTorch stores the gradients for all weights in each forward pass, filling up your memory very quickly. To prevent PyTorch from doing this, you can e.g. wrap the code for the forward pass in a torch.no_grad() context, such as

with torch.no_grad():

# your code here

Should this not work for you, or you face other issues in running the notebook for task 1, please let us know in the forum.

Best,

NNTI Tutors.
