Embodiment 1
[0099] In order to evaluate the beneficial effects of the present invention, the experiment compared three different algorithms - the traditional K-means algorithm, the MSTCluster algorithm based on the minimum spanning tree and the MNC algorithm in this paper, which clustered two-dimensional random data sets with different shapes The result is as Figure 5 . Since the traditional K-means is a parametric algorithm, that is, the input requires additional parameters besides the data set to be clustered, that is, the number of clusters k and the initial cluster center; MSTCluster based on the minimum spanning tree is compared with the traditional K-means It belongs to the non-parametric clustering algorithm, because it does not need to specify the number of clusters k and the initial cluster center, but in order to determine the pruning threshold, the algorithm still needs to input a parameter, that is, the adjustment factor, so the algorithm is not completely parametric; Howeve...
