Spectral clustering based on neighboring adaptive local scale
Considering the performance of traditional spectral clustering using Gaussian kernels
a new spectral clustering based on neighboring adaptive local scale is presented in this paper.Based on clustering consistency characteristics
the proposed method first emphasizes the flexibility of the local scale
which means each sample has a corresponding scale parameter.Furthermore
it overcomes the limitations of traditional methods in all samples with the same global scale parameter.Hence
it can depict the intrinsic structure of data sets better.Second
it stresses the convenience of parameter selection.It can determine the value of a local scale for one sample by computing the sum of weighted distances of neighbors.Therefore
it can determine the scale parameter automatically.This paper illustrates the proposed algorithm not only has inhibition for certain outliers but is able to cluster the data sets with different scales.Finally
