Abstract
Dimensionality reduction is a common method to reduce
the computational complexity of hyperspectral images and
improve the classification performance. Band selection is
one of the most commonly used methods for dimensionality
reduction. Affinity propagation (AP) is a clustering
algorithm that has better performance than traditional
clustering methods. This paper proposes an improved AP
algorithm (IAP), which divides each intrinsic cluster into
several subsets, and combines the information entropy to
change the initial availability matrix to obtain a suitable
number of clustering results with arbitrary shapes. The
experimental results on the public hyperspectral data set
show that the band combination selected by IAP has a better
classification accuracy compared with all bands data set and
band subset by traditional AP algorithm.
