Extraction of Classification Rules from Sequences of Crystal Growth Data

The paper presents a generalization of a data mining method for the extraction of classification rules for classification of sequences of events, which is called discriminant chronicles mining. The generalization is motivated by the objective to extract classification rules from crystal growth data, for which the original method needs to be extended to events with vectors of attributes and to real-valued attributes. The paper elaborates incorporating both extensions into the theoretical fundamentals of the original method, and describes a corresponding modification of a system for discriminant chronicles mining, which has been developed three years ago to implement the original method. Finally, an application of the generalized method, using the modified system for discriminant chronicles mining, to data from the growth of GaAs crystals by vertical gradient freeze method is briefly sketched.
