Extensible Data Pattern Searching Framework

CRAN Package

Extensible framework for subgroup discovery (Atzmueller (2015)), contrast patterns (Chen (2022)), emerging patterns (Dong (1999)), association rules (Agrawal (1994)) and conditional correlations (Hájek (1978)). Both crisp (Boolean, binary) and fuzzy data are supported. It generates conditions in the form of elementary conjunctions, evaluates them on a dataset and checks the induced sub-data for interesting statistical properties. A user-defined function may be defined to evaluate on each generated condition to search for custom patterns.
