Abstract

•A new interval partitioning method is purposed based on spectral clustering.•The purposed method can obtain discontinuous spectra intervals.•Obtained spectra intervals can be better explained than equal-width partitioning.•The purposed method helps interval selection algorithms get meaningful intervals.
