A small experiment with plain neural networks in C# (inside the Unity engine for visualizations), created as part of this video.
The code has some minor differences from that shown in the video, for example the weights array has been flattened to a one dimensional array for performance (although the performance is admittedly still pretty poor).
The project contains 4 image recognition experiments: mnist, fashion mnist, doodles, and cifar10.
In the future I plan to build upon this to create a convolutional neural network, and potentially move the calculations to the GPU to speed things up.
