SANCHEZ ALVAREZ, Reinaldo. Unsupervised classification of medical images and data mining: S3 algorithm vs. k-means. Rev Cubana Invest Bioméd [online]. 2021, vol.40, suppl.1, e1614.  Epub 01-Mar-2021. ISSN 0864-0300.

One of the challenges to be faced by programmers is the large dimensions of data groups. The process of pattern recognition in images and data mining for great volumes of information is an example. Optimizing the number of times that the set of data is run saves processing time. The purpose of the study was to characterize the three-step (S3) algorithm, parallel to k-means, as an alternative to cope with the large dimension of the data set in unsupervised image classification. Concurrence analysis is based on data flow and the single instruction multiple data scheme. The result obtained confirms that concurrence of both is possible. S3 does not depend on initial selection of representatives, and may be the process for selection of the first central vectors in k-means. S3 is an alternative to be considered in the unsupervised classification of medical images and data mining processes.
