3.3. Connection weight analysis of neural networks
Fig. 1 shows the results of the connection weight analysis of the neural networks trained to predict physical/chemical properties, while Fig. 2 shows the results of the same analysis applied to the networks trained to predict colour. In Fig. 1, the average influence of all three colour bands on each parameter is given, while in Fig. 2 the average influence of individual physical/chemical parameters on the colour bands is given. For both Figs. 1 and 2, it can be seen that the relative influence of colour on physical and chemical composition (or vice versa) varies greatly between parameters for the trained neural networks.
