Meta learning of bounds on the Bayes classifier error

no code implementations27 Apr 2015 Kevin R. Moon, Veronique Delouille, Alfred O. Hero III

For example, the Bayes error rate of a given feature space, if known, can be used to aid in choosing a classifier, as well as in feature selection and model selection for the base classifiers and the meta classifier.

Image patch analysis of sunspots and active regions. II. Clustering via matrix factorization

no code implementations10 Apr 2015 Kevin R. Moon, Veronique Delouille, Jimmy J. Li, Ruben De Visscher, Fraser Watson, Alfred O. Hero III

We also find that including data focused on the neutral line of an active region can result in an increased correspondence between our clustering results and other active region descriptors such as the Mount Wilson classifications and the $R$ value.

Image patch analysis and clustering of sunspots: a dimensionality reduction approach

no code implementations24 Jun 2014 Kevin R. Moon, Jimmy J. Li, Veronique Delouille, Fraser Watson, Alfred O. Hero III

Sunspots, as seen in white light or continuum images, are associated with regions of high magnetic activity on the Sun, visible on magnetogram images.
