The influence of the place-value structure of the Arabic number ...

learning pattern mirrored the one found for the purely holistic model with the diametrically
opposed development of connection weights for the two to-be-compared numbers.
Importantly, for the connection between the hidden layer and the output layer the connection
weights for the holistic part of the model developed similarly to the connection weights of the
unit digits of the decomposed part of the model and diametrically opposed to the weights for
the decade digits.
Figure D: Development of connection weights as observed for the decomposed part of the hybrid model (after
1.000, 10.000 and 50.000 training cycles). Again, the first row depicts connection between input and
hidden layer for the decade digits while the weights for the units are given in the second row. The
third row reflects the connection weights between hidden and output layer separated for tens and
units.
