Mine partially ordered gradual patterns from partially ordered valued sequence databases

gradualspan

Research paper, published at EGC 2018 (in French): http://www.editions-rnti.fr/?inprocid=1002382

Usage

Requires Java 8 and Maven.

Run with:

make run

This outputs graphs in valued-sequences.dot, gradual-sequences.dot and patterns.dot. To render these graphs, use bin/multidot <filename> (requires Graphviz to be installed).

Implementing your own backend

In this repository, two backends are implemented: a memory backend for unit tests and a PO² backend.

This implementation of GradualSpan is modular, you can implement you own backend pretty easily as long as you have a partially ordered valued sequence database. To do so, you need to implement the following interfaces: ValuedItem, ValuedNode and ValuedSequence.

gradualspan's Issues

Do not hardcode dataset paths

Hardcoded in pom.xml.

Write multiple dot files

dot doesn't support rendering multiple graphs from the same dot file.
