A yet more efficient high utility itemset mining algorithm (HAMM, to appear in IEEE TKDE)
Today, I will share the good news that I have participated as co-author in a paper proposing a new algorithm for high utility itemset mining called HAMM that is very efficient, and outperforms the state-of-the-art algorithm. This is not an … Continue reading
Introduction to Rare Itemset Mining
In the last decades, many data mining algorithms were developed to find interesting patterns in data (pattern mining). In particular, a lot of studies have been done about discovering frequent patterns (patterns that appear frequently) in a data. A classic … Continue reading
