Mining Frequent Itemsets from Data Streams with a Time-Sensitive Sliding Window

open access: yes, 2012
[[abstract]]Mining frequent itemsets has been widely studied over the last decade. Past research focuses on mining frequent itemsets from static databases. In many of the new applications, data flow through the Internet or sensor networks.

Efficient Incremental Mining of Top-K Frequent Closed Itemsets

open access: yes, 2007
In this work we study the mining of top-$K$ frequent closed itemsets, a recently proposed variant of the classical problem of mining frequent closed itemsets where the support threshold is chosen as the maximum value sufficient to guarantee that the ...

Mining maximal frequent itemsets from data streams

open access: yes, 2007
Frequent pattern mining from data streams is an active research topic in data mining. Existing research efforts often rely on a two-phase framework to discover frequent patterns: (1) using internal data structures to store meta-patterns obtained by ...

Efficient Frequent Itemsets Mining by Sampling

open access: yes, 2008
. As the first stage for discovering association rules, frequent itemsets mining is an important challenging task for large databases. Sampling provides an efficient way to get approximating answers in much shorter time.

Privacy-preserving algorithms for distributed mining of frequent itemsets

open access: yes, 2006
Standard algorithms for association rule mining are based on identification of frequent itemsets. In this paper, we study how to maintain privacy in distributed mining of fre-quent itemsets.

Mining Constrained Frequent Itemsets from Distributed Uncertain Data

open access: yes, 2014
Nowadays, high volumes of massive data can be generated from various sources (e.g., sensor data from environmental surveillance). Many existing distributed frequent itemset mining algorithms do not allow users to express the itemsets to be mined ...

Frequent Itemset Mining for Big Data.

open access: yes, 2017
Traditional data mining tools, developed to extract actionable knowledge from data, demonstrated to be inadequate to process the huge amount of data produced nowadays. Even the most popular algorithms related to Frequent Itemset Mining, an exploratory data analysis technique used to discover frequent items co-occurrences in a transactional dataset, are
