I found out I was passing incorrect input data to my forwarrd propagation function. After changing it to each_example it did work start to work with increasing accuracy over time. Now I never got accuracy of over .95 with the architecture but I'll take it. However, reading your comment, I gather I might have made some errs in back_prop, I'll look into it. I felt pretty confident about it because all the equations came from Ng's Stanford ML lecture. I followed along derived them myself using partial derv. Only Relu_prime came up during the back_prop in my case.
