# My solutions to all but crop2

It took a bit, but I finally cleaned up all my messy code 😂 - here's a notebook with my solutions! Thanks to the organizers - I learned a ton.

The most interesting things I learned were actually for crop2 (which is the only one I didn't finish)… I got really good at back-propping and modifying the input instead of the network (which is something I knew how to do in theory, but never did in practice), and how to inspect and manipulate the weights, biases, activations, and gradients for different layers of a network (which, as it turns out, was a big waste of time for crop2 😆 but was really fun to learn and try out).
I'll definitely look forward to the competition next year!
