WebFP Growth is one of the associative rule learning techniques which is used in machine learning for finding frequently occurring patterns. It is a rule-based machine learning model. It is a better version of Apriori method. This is represented in the form of a tree, maintaining the association between item sets. This is called Web13 mrt. 2024 · 相反,FP-Growth算法通过构建一种称为FP树的数据结构来高效地挖掘频繁项集,该算法首先通过扫描数据集来生成一个频繁模式基(即每个项出现的次数),然后构建FP树,其中每个路径表示一种频繁项集。然后使用树的节点链接来高效地查找频繁项集。
