What do you mean by Associative Rule Mining (ARM)?

Associative Rule Mining is one of the techniques to discover patterns in data like features (dimensions) which occur together and features (dimensions) which are correlated. It is mostly used in Market-based Analysis to find how frequently an itemset occurs in a transaction. Association rules have to satisfy minimum support and minimum confidence at the very same time. Association rule generation generally comprised of two different steps:

  • “A min support threshold is given to obtain all frequent item-sets in a database.”
  • “A min confidence constraint is given to these frequent item-sets in order to form the association rules.”
    Support is a measure of how often the “item set” appears in the data set and Confidence is a measure of how often a particular rule has been found to be true.
