  section below

header

 Encoding:
===========

Output: The output encoding is a 1-of-2 encoding as follows:
          edible: 1 0  poisonous: 0 1
Input:  Each n-valued nominal input is represented by a 1-of-n encoding
        using n input values. The relevant input is 1, others are 0.
        This results in having 125 input values to the network:
