    Let me give you an example of “frequent pattern mining” in grocery stores. Customers go to Walmart, tesco, Carrefour, you name it, and put everything they want into their baskets and at the end they check out. Let’s agree on a few terms here: * T:...

How to auto-adjust the minimum support threshold according ...

    http://data-mining.philippe-fournier-viger.com/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 the Apriori algorithm. The input of this algorithm is a transaction database and a parameter called minsup that is a value in [0,1].

Mining Association Rules with Multiple Minimum Supports

    http://www.philippe-fournier-viger.com/spmf/MISApriori.pdf
    Association rule mining is an important model in data mining. Its mining algorithms discover all item associations (or rules) in the data that satisfy the user-specified minimum support (minsup) and minimum confidence (minconf) constraints. Minsup controls the minimum …

Data mining — Defining minimum support

    https://www.ibm.com/support/knowledgecenter/en/SSEPGG_10.1.0/com.ibm.im.model.doc/c_defining_minimum_support.html
    To define the minimum support that a rule must exceed to be calculated, use the DM_setMinSupport method to set the minimum support in the DM_RuleSettings value such as: IDMMX.DM_RuleSettings()..DM_setMinSupport(25) If you do not set the minimum support, the algorithm estimates a useful level for it.
