This is a video presentation of the Apriori algorithm for discovering frequent itemsets in data.  The Java source code of the Apriori algorithm and datasets for evaluating its performance are available in the SPMF software. If you want to … Continue reading

How to auto-adjust the minimum support threshold according to the data size

Today, I will do a quick post on how to automatically adjust the minimum support threshold of frequent pattern mining algorithms such as Apriori, FPGrowth and PrefixSpan according to the size of the data. The problem is simple.  Let’s consider … Continue reading
