DCI-Closed

DCI-Closed, a frequent closed itemset mining algorithm, implemented in Rust.

Features

• Two flavors: sequential and parallel.
• Dataset generic: you can use your own dataset type.
• Optional bitmatrix dataset support.
• No unsafe code.

Background

The implementation is based on the original paper, by Lucchese, C. et al. The parallel flavor is a trivial Rayon spin of the original algorithm.

Changelog

• 0.3.0:
  Bugfix: report the closed set of all items which occur in all transactions.
  Replace vector return type with boxed slice.
• 0.2.0: Add Into<BitMatrix> implementation for Matrix.
• 0.1.0: Initial version.
