nuggets: Extensible Data Pattern Searching Framework
Extensible framework for subgroup discovery (Atzmueller (2015) <doi:10.1002/widm.1144>), contrast patterns (Chen (2022) <doi:10.48550/arXiv.2209.13556>), emerging patterns (Dong (1999) <doi:10.1145/312129.312191>) and association rules (Agrawal (1994) <https://www.vldb.org/conf/1994/P487.PDF>). Both crisp (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. Currently, the package searches for implicative association rules and conditional correlations (Hájek (1978) <doi:10.1007/978-3-642-66943-9>). A user-defined function may be defined to evaluate on each generated condition to search for custom patterns.
