The component plane calculated using SOM to visualize these overall relationships is shown in Fig. 7.9. A higher EPS production was linked to a higher k EPS, while the total EPS production had no such a strong relationship with μ H, K S, and Y H. The results from a correlation analysis comprising the input parameters μ H, K S, Y H and k EPS, and the target variable (EPS production) were in agreement with the results shown in Fig. 7.9, highlighting the key relationships revealed by the SOM. The k EPS, as key parameter, correlated positively with the EPS production (R = 0.970, see Fig. 7.9), indicating a higher k EPS would result in more EPS production.
