Embodiment Construction
[0047] The present invention will be further described below in conjunction with the accompanying drawings.
[0048] refer to Figure 1 ~ Figure 4 , a data classification method based on the negative selection algorithm of self-set density search and partition clustering, the data classification method includes the following steps:
[0049] 1) Calculate the cluster center and delete the noise according to the density peak value of the data set;
[0050] 2) Generate a self-detector from non-noisy self-samples;
[0051] 3) Generate non-self detectors from self detectors;
[0052] 4) Use the self-detector and the non-self-detector at the same time to judge whether the detected data samples are abnormal, and realize data classification.
[0053] refer to figure 1 and figure 2 , the self-set clustering process is as follows:
[0054] 1.1) Calculate the ρ of each point in the data set according to the formula i and δ i , ρ i is the density of the i-th data point, δ i is t...
