My goal is to implement a feedforward neural network using Andrew Ng's course on youtube. Here, there is no separate bias matrix used. I am not able to get the delta_weight matrix match dimension with weight matrix, which I can subsequently subtract to reduce error.

If anyone could help spot the potential errors in the logic shown below, that would be amazing.

Thanks in advance!

    $\begingroup$ From 1 to 2, weight matrix should be 4x3 as there are 4 nodes in 2nd layer. $\endgroup$ – Ankit Seth Aug 2 '20 at 14:50
