The SPMF data mining software is a popular open-source software for discovering patterns in data and for performing other data mining tasks. Typically, to run SPMF, Java must have been installed on a computer. However, it is possible to run … Continue reading
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 … Continue reading
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 K-Means algorithm with an example. Moreover, I will briefly explain how an open-source Java implementation of … Continue reading
This blog post briefly explain how time series data mining can be performed with the Java open-source data mining library SPMF (v.2.06). It first explain what is a time series and then discuss how data mining can be performed on time series. What is … Continue reading
In this blog post, I will give an introduction about a popular problem in data mining, which is called “high-utility itemset mining” or more generally utility mining. I will give an overview of this problem, explains why it is interesting, and provide source code of … Continue reading
In this blog post, I will explain and provide source code to automatically draw the powerset of a set using Java and GraphViz. Drawing a powerset is useful in mathematics and also in computer science, for example in frequent itemset mining, it can … Continue reading
Today, I will discuss the topic of accurately evaluating the memory usage of data mining algorithms in Java. I will share several problems that I have discovered with memory measurements in Java for data miners and strategies to avoid these … Continue reading
Hi everyone, In this blog post, I will discuss how I have applied an open-source tool that is named Code Analyzer ( http://sourceforge.net/projects/codeanalyze-gpl/ ) to analyze the source code of my open-source data mining software named SPMF. I have applied … Continue reading
Hi, I have made a map to visualize the relationship between the 52 different data mining algorithms offered in the SPMF data mining software. You can view it in PNG format by clicking on the picture below: Or you can … Continue reading
