WebJul 10, 2024 · suggested an Apriori-like candidate set generation and test approach. But it is pretty slow, and it becomes slower when there are many patterns available in mining. Therefore, FP-tree is proposed. The alternative of the apriori-like algorithm, the frequent-pattern tree(FP-tree) structure, is a tree data structure for storing frequent patterns. WebExecution time of an algorithm depends on the instruction set, processor speed, disk I/O speed, etc. Hence, we estimate the efficiency of an algorithm asymptotically. Time function of an algorithm is represented by T(n), where n is the input size. Different types of asymptotic notations are used to represent the complexity of an algorithm.
