which_antichain

The function returns indices of elements from the given list <code>x</code>, which are incomparable
(i.e., it is neither subset nor superset) with any preceding element. The first element
is always selected. The next element is selected only if it is incomparable with all
previously selected elements.

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.
