How to call SPMF from another Java program as an external program?
This is a short blog post where I will explain how to call SPMF as an external program from another Java program to execute an algorithm. Before we start, it should be said that there are multiple ways to use … Continue reading
Introduction to the Apriori algorithm (with Java code)
This blog post provides an introduction to the Apriori algorithm, a classic data mining algorithm for the problem of frequent itemset mining. Although Apriori was introduced in 1993, more than 20 years ago, Apriori remains one of the most important data mining algorithms, not because it is the fastest, but because it has … Continue reading

Introduction to clustering: the KMeans algorithm (with Java code)
In this blog post, I will introduce the popular data mining task of clustering (also called cluster analysis). I will explain what is the goal of clustering, and then introduce the popular KMeans algorithm with an example. Moreover, I will briefly explain how an opensource Java implementation of … Continue reading
