I'm programming a MNIST number recognizer using neural networks. I have a general understanding of the forward propagation and dot products where when I take a 10 number matrix and multiply it with another 10 number matrix I will receive a SINGLE summation.
Now after forward propagation is BACKWARDS PROPAGATION. This is whats really tripping me up right now. The python program I am looking at does a dot product between two 10 number matrices and returns a 10x10 matrix. Mathematically how the fuck is this happening!?
