Mining Target-Oriented Sequential Patterns with Time-Intervals [PDF]

open access: yes, 2010
A target-oriented sequential pattern is a sequential pattern with a concerned itemset in the end of pattern. A time-interval sequential pattern is a sequential pattern with time-intervals between every pair of successive itemsets.

Sliding Window-based Frequent Itemsets Mining over Data Streams using Tail Pointer Table [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2014
Mining frequent itemsets over transaction data streams is critical for many applications, such as wireless sensor networks, analysis of retail market data, and stock market predication.

Binary image description using frequent itemsets

open access: yesJournal of Big Data, 2020
In this paper, a novel method for binary image comparison is presented. We suppose that the image is a set of transactions and items. The proposed method applies along rows and columns of an image; this image is represented by all frequent itemset ...

Mining Top-K Frequent Itemsets Through Progressive Sampling

open access: yes, 2010
We study the use of sampling for efficiently mining the top-K frequent itemsets of cardinality at most w. To this purpose, we define an approximation to the top-K frequent itemsets to be a family of itemsets which includes (resp., excludes) all very ...

Mining Frequent Itemsets in a Stream [PDF]

open access: yesSeventh IEEE International Conference on Data Mining (ICDM 2007), 2007
We study the problem of finding frequent itemsets in a continuous stream of transactions. The current frequency of an itemset in a stream is defined as its maximal frequency over all possible windows in the stream from any point in the past until the current state that satisfy a minimal length constraint.

An Efficient Rigorous Approach for Identifying Statistically Significant Frequent Itemsets [PDF]

open access: yes, 2009
As advances in technology allow for the collection, storage, and analysis of vast amounts of data, the task of screening and assessing the significance of discovered patterns is becoming a major challenge in data mining applications.

Mining Frequent Itemsets Using Genetic Algorithm

open access: yes, 2010
In general frequent itemsets are generated from large data sets by applying association rule mining algorithms like Apriori, Partition, Pincer-Search, Incremental, Border algorithm etc., which take too much computer time to compute all the frequent ...

High Quality, Efficient Hierarchical Document Clustering Using Closed Interesting Itemsets [PDF]

open access: yes, 2006
High dimensionality remains a significant challenge for document clustering. Recent approaches used frequent itemsets and closed frequent itemsets to reduce dimensionality, and to improve the efficiency of hierarchical document clustering. In this paper,

Mining Productive Itemsets in Dynamic Databases

open access: yesIEEE Access, 2020
Discovering frequent itemsets is a data analysis task used in numerous domains. It consists of finding sets of items (itemsets) that frequently appear in a set of database records (also called transactions). Though discovering frequent itemsets is useful,
