Neural Networks: Theory and Implementation

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. The submission is open until Friday 15th 23:59.

Good luck with the rest of the project and have a nice week!

Hi all,

we have just released the grades for the final exam. You can find them on your personal status page below your cluster credentials. If you attended the exam but your personal status page says "No value available", please notify us immediately.

PS: Don't be afraid of negative values, this means your exam grade is 1.0.

Best,

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.

Hi,

 

despite my message: https://cms.sic.saarland/nnti/news/view/32

 

again a team managed today to run a job (a jupyter notebook) on the submit node. This blocks the CS compute cluster for all of CS!!!!

Again the strong reminder: no computations on conduit.hpc.uni-saarland.de !

 

Best regards,

Hi,

 

the NNTI exam tomorrow will be split between GHH (E22) and the large lecture hall in physics (C63/C64).

You can find the assigment in the materials section:

https://cms.sic.saarland/nnti/dl/37/Lecture_halll_assigment_NNTI.pdf

Please check carefully which lecture hall you will be in. The exam starts at 14:00 sharp. Please make sure that you arrive at the respective lecture hall at 13:45 .

Best regards,

 

Dietrich Klakow

 

 

 

 

 

 

 

Hi,

for the project presentations here is a google table were you can book slots:

https://docs.google.com/spreadsheets/d/1B_teP-PpPtZGxuZrK6Sw4UPL_K5KQ-idvWvf3M2TC10/edit?usp=sharing

Please enter all names of the team members or all matriculation numbers of the team members. Please continue with the teams from the assignments.

The presentation should be 15min with all team members having roughly an equal share in presenting.

The remaining time is for questions.

Best regards,

 

Dietrich Klakow

Hi,

Happy New Year! I hope that many of you can make it in person to the lecture tomorrow. If not (as announced below) there is also the option to participate online:

https://teams.microsoft.com/l/meetup-join/19%3ameeting_ZjQ2ZTljYWMtZWM3Mi00NzIwLWEwYTMtZDRlYmMzYTBkN2Qx%40thread.v2/0?context=%7b%22Tid%22%3a%2267610027-1ac3-49b6-8641-ccd83ce1b01f%22%2c%22Oid%22%3a%22649aab9b-646c-4d62-a3a8-f56d5fe6561f%22%7d

Sound will be run via my laptop, so no guarantees about the quality.

See you

Dietrich Klakow
 

Hey everyone, 

we have just released the sixth assignment. You can find the PDF under Materials. This week, the practical part requires you to run your code on the sic-cluster. We have distributed credentials to each of you and you should be able to find them on your Personal Status page. If you cannot find your credentials on your personal status page, please notify us as soon as possible! The deadline is, as always, next Thursday, 23:59.

Kind regards and good luck,

NNTI Tutors

Hi everyone,

we have just made some small fixes for Exercise 3.2b in the current assignment. In summary, the first expression to show was missing an argmin_D on the left-hand side and an argmax_D on the right-hand side. Additionally, there was some confusion as to whether the eigenvectors of XtX are the columns or rows of D. This should all be fixed now. You can find the new version in the Materials section of the CMS.

Good luck with the assignment and have a nice week!

NNTI Tutors

Hi everyone,

to avoid issues with the grading of the assignments we have changed the team grouping deadline to tomorrow evening 23:59. Afterwards teams are fixed and you can no longer create or change teams.

As a quick reminder, the deadline for the submission of your tutorial slot preferences is also tomorrow evening at 23:59.

Have a nice week!

NNTI Tutors

Hi, we just had discussed the Christmas break in the tutor meeting.

There will be no lecture on December 19th (due to an RTG retreat DK has to attend) and we will not issue a new assignment in that week. Tutorials will happen as planned.

In the week stating January 2nd, there will be a lecture which will be offered hybrid. Sound will be via laptop so now guarantees for the audio quality. There will be no tutorials in the first week of January.

Hi everyone,

thank you all for notifying us that many of you were not able to set their tutorial preferences here in the CMS. We have fixed that and all of you should be able to set them now on the Personal Status page. Please check if that is possible. Also, if you were able to set your tutorial preferences already, please check that they are still correctly set. The new deadline for submitting your preferences is next Thursday, Nov 16th at 23:59.

As a quick reminder, tutorials nonetheless start next week and you are free to go to the slot you like until we have made the tutorial assignments.

Best,

NNTI Tutors

Hi everyone, 

we just released the second assignment. You can find both files in the Materials section. Note that the zip file contains both the PDF with the theoretical exercises as well as the notebook for the practical part. Your solutions must be uploaded to the CMS via your Personal Status page by one of the team members by next Thursday, 23:59.

Kind regards and good luck,

NNTI Tutors

Hello everyone,

to answer a common question, you will keep eligibility for the NNTI exam if you have obtained it in a previous semester. However, the contents of the assignments from this semester are relevant for the exam, so it is still recommended that you look at them.
The project is mandatory for everyone.

Kind regards,

NNIA Tutors

Hi,

Dear Students,

The submission link for Assignment 1 has been created. The assigments are to be completed collaboratively, with each group consisting of no more than three members. Please note that a submission made by any one member will be recognized as a submission on behalf of the entire group.

Kindly be reminded that the deadline for submitting Assignment 1 is Thursday, November 9, 2023, at 23:59.
