基于局部敏感哈希的频繁项集挖掘

Frequent-Itemset Mining using Locality-Sensitive Hashing

Debajyoti Bera, Rameshwar Pratap

摘要:

Apriori算法是频繁项集挖掘的经典算法。Apriori中的一个重要瓶颈是所涉及的I/O操作的数量以及它生成的候选项的数量。我们调查LSH技术的作用,以克服这些问题,而不增加太多的计算开销。我们提出了随机变化的Apriori的基础上定义的汉明距离和Jaccard相似性的非对称LSH。

英文摘要:

The Apriori algorithm is a classical algorithm for the frequent itemset mining problem. A significant bottleneck in Apriori is the number of I/O operation involved, and the number of candidates it generates. We investigate the role of LSH techniques to overcome these problems, without adding much computational overhead. We propose randomized variations of Apriori that are based on asymmetric LSH defined over Hamming distance and Jaccard similarity.
