Data Mining By Parallelization of Fp-Growth AlgorithmIn this paper we present idea to make one main tree on master node and slave do processing with database rather than have multiple FP-trees, one for each processor Firstly, the dataset is divided equally among all participating processors Pi....
首先,将事务数据集转换为布尔矩阵表示,然后调用fpgrowth函数来寻找指定最小支持度阈值的频繁项集。 另外,如果你想使用自己实现的FP-Growth算法,可以参考相关的开源实现和算法细节。以下是一些学习资源,可以帮助你更深入地了解FP-Growth算法: Han, J., Pei, J., & Yin, Y. (2000). Mining frequent patterns wit...
