Five years ago, I had analyzed the source code of the SPMF data mining software using an open-source tool called CodeAnalyzer ( http://sourceforge.net/projects/codeanalyze-gpl/ ). This had provided some interesting insights about the structure of the project, especially in terms of … Continue reading
In this blog post, I will offer a glimpse of my plan for improving the user interface of the SPMF data mining sofware. I have designed a sketch of an improved user interface using the open-source Pencil prototyping software. Here is … 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
A while ago, I had written a blog post about How to measure the memory usage of algorithms in Java. Today, I will discuss the topic of optimizing the memory usage of algorithms written in Java to design memory-efficient data mining algorithms. … 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
In this blog post, I will discuss how to check if a data mining algorithm implementation is correct and complete. This is a very important topic for researchers who are implementing data mining algorithms since an incorrect implementation may generate unexpected results. … Continue reading
In this blog post, I will explain and provide source code to automatically draw the set-enumeration tree of a set using Java and GraphViz. Drawing a set-enumeration tree is useful in computer science, for example in frequent itemset mining, a subfield of data … Continue reading
Today, I will discuss the topic of Big Data, which is a very popular topic nowadays. The popularity of big data can be seen for example in universities. Many universities are currently searching for professors who do research on “big data”. Moreover, … Continue reading
Today, I will show how to use the open-source SPMF data mining software to discover sequential patterns in web log data. Then, I will show to how visualize the frequent sequential patterns found, using GraphViz. Step 1 : getting the … Continue reading
