Constud is a software system for 1) calculating spatial indices, 2) machine learning of weights for explanatory variables and for observations, 3) for similarity-based prediction of dependent variables. See more detailed description. The source code of Constud is written in Visual Basic in Microsoft Visual Studio 2010 environment.

Calculation of similarity is a central task in similarity-based learning and prediction. In Constud, it is applied in two subroutines depending on the use of a preclassifier.
