This crate provides parallel and sequential implementations of the DCI-Closed algorithm.
It provides a generic trait for the dataset type, and a default implementation based on bitmatrix.
sequential: enables the sequential implementation. You probably should prefer the parallel one.
parallel: enables the rayon based parallel implementation.
matrix: enables the
A DataSet implemented as a BitMatrix, from the
A trait for a DataSet. The algorithm can operate over any type that implements this trait. It is highly recommended to implement this datastruct as a bit matrix, and its associated types as bitsets, in order to obtain optimal performance.
A trait for an ItemSet. ItemSets must be owned, cloneable and iterable. Once again, a bitset implementation is highly recommended.
The support type, i.e. how many transactions contain a given item or itemset.
