[0044] Example
[0045] See attached figure 1 with figure 2 , Attached figure 1 And figure 2 It is a flowchart of the sewage treatment fault diagnosis method based on the weighted extreme learning machine integration algorithm in this embodiment. The experimental simulation data comes from the University of California database (UCI), which is the daily monitoring data of a sewage treatment plant. The dimension of each sample of the entire data set is 38. There are 380 complete records of all attribute values. The monitored water bodies are in total. There are 13 states, each state is replaced by a number. In order to simplify the complexity of classification, we divide the samples into 4 categories according to the nature of the sample categories, as shown in Table 1. In Table 1, category 1 is a normal condition, category 2 is a normal condition with performance exceeding the average value, category 3 is a normal condition with low water inflow, and category 4 is a secondary...
