A mathematical problem at the heart of one the most commonly used algorithm in Machine Learning, Backpropogation. A simple video made in 1 day for SoME to explain the maths behind the problem and how it's usually dealt with out in the wild.

Thank you for putting in the effort of making a video. As for criticisms: Slow down. Take breaks or pauses in the video. Use methods to emphasize or break up text. Like coloring.

The audio quality is acceptable, but for the future, if it’s possible for you, try to improve it. It’s sometimes difficult to understand you without turning my audio volume up to dangerous levels. Communicating math well also means that people should be able to hear you well.

Regarding the video’s visuals, it’s totally okay to use a pen and a paper to visualize the math. But I often could not read/decipher what you’ve written because of your handwriting and spacing. The visuals don’t have to be amazing, but I should at least be able to read something without having to look twice and coming close to my monitor.

As someone who’s new to the intricacies of AI and backpropagation, I feel like this video needs a bit more exposition. I know that’s difficult to do in a single day, but after watching the video I just don’t know why I should care about this topic. For example, if you had shown a bit more about your motivation to create your own AI model, its applied context, the history of backpropagation, and so on, it would have been a more enjoyable video to watch.

After watching the video a few times I have to admit that I still understand nothing, at least concerning the math you’ve shown. I personally need a bit more context and better visualizations to understand such a subjectively complex topic.

I found this video to be confusing and not very helpful. For one thing, the video is essentially just a lecture, and doesn’t make use of the medium to do things that can’t be done in a lecture. I think the target audience would immediately “click away” from such a video. I think trying to make a video in one day and enter it into this contest was a bad idea, as most creators will spends weeks (or longer) creating their videos.
