nuggets-package: nuggets: Extensible Data Pattern Searching Framework

Description

Extensible framework for subgroup discovery (Atzmueller (2015) tools:::Rd_expr_doi("10.1002/widm.1144")), contrast patterns (Chen (2022) tools:::Rd_expr_doi("10.48550/arXiv.2209.13556")), emerging patterns (Dong (1999) tools:::Rd_expr_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) tools:::Rd_expr_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.
