Upcoming book: High Utility Itemset Mining: Theory, Algorithms and Applications

I am happy to announce that the draft of the book about high utility pattern mining has been finalized and submitted to the publisher (Springer). It should thus be published in the very near future. The book contains 12 chapters written … Continue reading

On the Completeness of the CloSpan and IncSpan algorithms

In this blog post, I will briefly discuss the fact that the popular CloSpan algorithm for frequent sequential pattern mining is an incomplete algorithm.  This means that in some special situations, CloSpan does not produce the expected results that it has been designed for, and … Continue reading

On the correctness of the FSMS algorithm for frequent subgraph mining

In this blog post, I will explain why the FSMS algorithm for frequent subgraph mining is an incorrect algorithm.  I will publish this blog post because I have found that the algorithm is incorrect after spending a few days to … Continue reading

How to discover interesting patterns in data?

Discovering interesting patterns in data is often referred as data mining, data science or big data.  In the last few years, I have written several blog posts providing introduction to data mining and key topics in data mining: An Introduction to … Continue reading
