Intelligent Data Analysis   22(4) 751-765   2018   [Refereed]
The similarity measure for complex data may not precisely reflect the true data structure, which leads to suboptimal clustering performance for spectral clustering. In this paper, we propose a novel spectral clustering method which measures the si...
