Auto Class? C is a public domain version of Auto Class? III, with some improvements from Auto Class? X, implemented in the C language.
Auto Class? is an unsupervised Bayesian classification system that seeks a maximum posterior probability classification.
Inputs consist of a database of attribute vectors (cases), either real or discrete valued, and a class model. Default class models are provided. Auto Class? finds the set of classes that is maximally probable with respect to the data and model. The output is a set of class descriptions, and partial membership of the cases in the classes. A DOS port is now available.
