TXMeans 0.1.1

parameter-free clustering algorithm

TX-Means

TX-Means is a parameter-free clustering algorithm able to efficiently partitioning transactional data in a completely automatic way. TX-Means is designed for the case where clustering must be applied on a massive number of different datasets, for instance when a large set of users need to be analyzed individually and each of them has generated a long history of transactions.

In this repository we provide the source code of TX-Means, the clustering algorithm competitors and the dataset used in

Riccardo Guidotti, Anna Monreale, Mirco Nanni, Fosca Giannotti, Dino Pedreschi "Clustering Individual Transactional Data for Masses of Users", KDD 2017, 2017, Halifax, NS, Canada

Please cite the paper above if you use our code or dataets.
