I've been following Stanford course CS231n: Convolutional Neural Networks for Visual Recognition in my internship program at Rayanesh company. Here I gathered my notes and solutions to assignments. The course lectures were recorded in Spring 2017, but the assignments are from Spring 2021.

Some concepts in assignments like transformers or Self-Supervised learning are not taught in the 2017 lectures. Self-Supervised learning question is solved, but transformers question is skipped. The Style Transfer question was omitted in the 2021 assignments, so I returned to the 2017 homeworks to solve that.
