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.
