Hey 
Ok i reached feed foward neural networks.
I have some questions, i was wondering if you guys can help me find the answer 
A)I made a program in java with hopfield that recognizes a pattern of a matrix, and when you present it with a small wrong error, it returns the correct image…
How i do that with feedfoward and backpropagation?
Here’s what i meant : https://www.youtube.com/watch?v=CRA-wVQLdhU
B)In hopfield i cant train more than 1 pattern… Can i do that with feedfoward ?
C)Can i have any function that i want for training?
Thanks guys
I will post more code when i finish my matrix API
