Today, I want to announce that I have just made public datasets of 30 novels from English Novels from 10 authors of the XIX century. These datasets can be used for testing algorithms for sequential pattern mining, sequential rule mining, … Continue reading
Hi all, this is to announce that a new textbook in Thai has been published about pattern mining, which includes many examples using the SPMF software. The textbook named “Pattern Mining: Theory and Practice” is written by teacher Panida Songram … Continue reading
Today, I present a video about finding stable periodic patterns in data, and discuss a new algorithm named SPP-Growth for this task. The SPP-Growth algorithm and datasets for evaluating its performance are available in the SPMF software, which is open-source and programmed in … Continue reading
Hi all, I am please to announce that a new version of SPMF has just been published (v 2.40). It contains 9 novel algorithms: the HUIM-ABC algorithm for mining high utility itemsets using Artificial Bee Colony Optimization (thanks to Wei Song and Chaoming Huang for … Continue reading
This is a video presentation of the Apriori algorithm for discovering frequent itemsets in data. Frequent itemset mining is one of the most popular data mining task. The Java source code of the Apriori algorithm and datasets for evaluating … Continue reading
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
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
This blog post is to let you know that I have just published a new version of the SPMF open-source Java data mining library (0.98) that offers a new window for visualizing the patterns found by data mining algorithms. This … Continue reading
In this blog post, I will talk about the well-known open-source library of data mining algorithms implemented in Java, which I am the founder of. I will give a brief overview of its history, discuss some lessons learned from the development of … Continue reading
