The PrefixSpan algorithm (video)
I have posted a new video about pattern mining, explaining the PrefixSpan algorithm. It assumes that you know already what is sequential pattern mining. If you are not familiar with sequential pattern mining, you can first watch my video Introduction … 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 … Continue reading
