Efficient robust methods via monitoring for clustering and multivariate data analysis
作者:
Highlights:
• A new data-dependent method for determining the trimming level in robust clustering.
• We monitor the cluster structure as the trimming level changes.
• The robust clustering constrains the ratio of eigenvalues of dispersion matrices.
• The “car-bike” plot exhibits cluster stability as the eigenvalue constraint varies.
• Sizable bibliography relating the work to that in the machine learning and pattern recognition fields.
