Market Basket Analysis
The "Market Basket Analysis" extension consists of the operators that build upon the association rule mining framework, but provide additional analytic capabilities beyond simple associations. These includes an operator to mine negative patterns represented as dissociation itemsets and dissociation rules, an operator for mining substitutive itemsets, that is the itemsets that can be used interchangeably as substitutes, i.e. the ones that appear in the transactional database in very similar contexts, and finally an operator that computes recommendation rules that uses an additional itemset interestingness measure, namely coverage, to construct a set of recommended items using a greedy search procedure. All operators accept the collection of discovered frequent patterns as input data, and produce itemsets and rules as their outputs.
The Market Basket Extension can be downloaded from the Rapid-I Marketplace from within RapidMiner. Details are available here.
