For that, I need to generate itemsets of length k+1 from itemsets of length k (given as a dictionary L). The Apriori principle must be followed in generating the combinations. The principle states: A set of length k+1 can only be generated if ALL its subsets are present in the input, L. WebMany frequent itemset mining algorithms have been re-designed on the Spark, and most of them are Apriori-based. All these Spark-based Apriori algorithms use Hash Tree as the underlying data structure. stedt application form
