Construction and Application of Agricultural Talent Training Model Based on AHP-KNN Algorithm

Figure 3

Example of improved KNN algorithm.

(a) There are exactly two types of samples with the same number of adjacent samples

(b) There are three types of adjacent samples

(c) The average distance between two types of selected adjacent samples is equal (second classification)

(d) The average distance between two types of selected adjacent samples is equal (multiclassification)
