(4) Selection of all (33) indicator selection (fig. 7) Normalized Entropy of Covariance matrix: 0.725 Accuracy: 0.977 Basically, the f1-score increases as the number of data items increases. However, the entropy is not much different from that in Figure 6. It is thought that there is not much change in the data structure. Therefore, the appropriate number of items (indicators) to represent the data structure is thought to be smaller.
