It seems powerless when dealing with massive data sets. The Frequent Pattern (FP)-Growth method is used with databases and not with streams. FP-Growth is an algorithm to find frequent patterns from transactions without generating a candidate itemset. To overcome these redundant steps, a new association-rule mining algorithm was developed named Frequent Pattern Growth Algorithm.

Introduction Medical data has more complexities to use for data mining implementation because of its multi dimensional attributes. Usually, there is a pattern in what the customers buy. Iteratively reduces the minimum support until it finds the required number of rules with the given minimum metric. Rather than defining groups before looking at the data, clustering allows you to find and analyze the groups that have formed organically. It’s a mathematical formula created by Dr. S have been relative trailblazers in their adoption of FP&A as a vital business tool. FP-growth exploits an (often-valid) assumption that many transactions will have items in common to build a prefix tree. It overcomes the disadvantages of the Apriori algorithm by storing all the transactions in a Trie Data Structure. data mining fp growth | data mining fp growth algorithm | data mining fp tree example | fp growth - Duration: 14:17.
