First of all thanks so much for setting up this course!
I completed the first lesson I and trained a model that can classify chords written in sheet music as major or minor, with 100% (for my own curated dataset). One caveat is that the dataset is very clean, so heavily biased to a specific template format which applies to all the images. I imagine I’d have to extend my dataset much more to make this model application more useful.
That said, the purpose of this task was to learn a bit more about deep learning and I’m very proud I managed to do it.
