This repository contains my solutions of the assignments of the Stanford CS224N: Natural Language Processing with Deep Learning course from winter 2022/23. There are many other great repositories on this course but none that cover the latest assignments (winter 2022 / 2023) and contain the written and practical parts completely (state: Mai 12. 2023). This repository is intended as a learning ressource which provides answers if you are stuck. Please do yourself a favor and try it on your own first. If you come across any errors or like me to include a more expressive explanation, please let me know at florian.kark@hhu.de.
Reading papers is an important part of this course and crucial for completing the assignments successfully. Therefore I recommend to have a look at How to read a Paper
From Assignment 2 and onwards you will need to edit latex files for your written solutions. I can recommend this wikibook as an up-to-date, comprehensive, and accessible reference. To have git integration I would use Vscode with a LateX extension as a LateX editor. For personal use, overleaf might be easier and quicker to use.
For now, all assignments are completed. I will continue watching the rest of the lectures and come back in September this year to try completing one of the default projects.
