pypatternminer 0.1.1

Open-source Python library for pattern mining

pypatternminer

pypatternminer is an open-source Python library for pattern mining. It provides a broad, research-oriented, and reproducible framework for major pattern-mining families, including:

• Itemset mining
• High-utility itemset mining
• High-utility sequential pattern mining
• Sequential pattern mining

The project is developed with two main goals:

1. to provide a comprehensive Python framework covering many influential pattern-mining algorithms in a unified environment;
2. to provide publicly available code and testing datasets to support transparent and reproducible research.

Why pypatternminer?

Pattern mining has produced a large number of important algorithms over the past three decades, but the Python ecosystem remains relatively fragmented. pypatternminer aims to help bridge this gap by offering:

• a unified Python environment for multiple pattern-mining families;
• broad algorithmic coverage;
• validation against SPMF reference implementations;
• public access to source code and testing datasets;
• a foundation for teaching, benchmarking, and future research.

Current Coverage

At the current stage, pypatternminer includes 144 implemented entries:

Category	Implemented
Itemset mining	42
High-utility itemset mining	70
High-utility sequential pattern mining	3
Sequential pattern mining	29
Total	144

Planned future extensions include:

• association rule mining
• sequential rule mining
• sequence prediction
• periodic pattern mining
• episode mining

Validation

A key design principle of pypatternminer is implementation reliability.

Each Python implementation is validated against the corresponding Java implementation in SPMF using:

• the same input datasets,
• the same parameter settings,
• and the same experimental conditions.

The returned pattern sets and associated values, such as support or utility, are compared to ensure matching outputs.
