Problem

The NN.py program does not train properly when using 2 or more hidden layers.

Possible Errors

The cause of this problem is currently unknown.

1. Most likely a problem with the backpropagation algorithm.
   1. Backpropagation function may not be implemented fully/completely correct.
      1. Error is most likely a problem where the layer error is incorrectly calculated.
   2. There may be a minor error in the code for the backpropagation function.
2. Potentially a slight code/logic error in forward pass method.

Methods To Find A Solution

*More research will be done on the backpropagation function to see what may have been implemented incorrectly.
*A review of the code will be performed in case it turns out to be a minor algorithm error.
