Analysis of Digital POSS-II Catalogs Using Hierarchical Unsupervised Learning Algorithms
We apply techniques from the eld of machine learning/ artiicial intelligence to the problem of inducing meaningful structure from astronomical data. Cobweb/95 is a concept formation system that accepts objects incrementally and organizes them into a classiication tree. The system has been successfully applied to cluster sky objects which were derived from the SKICAT data cataloging/analysis system.
