LCM: An Efficient Algorithm for Enumerating Frequent Closed Item Sets
In this paper, we propose three algorithms LCMfreq, LCM, and LCMmax for mining all frequent sets, frequent closed item sets, and maximal frequent sets, respectively, from transaction databases. The main theoretical contribution is that we construct treeshaped transversal routes composed of only frequent closed item sets, which is induced by a parent-child relationship defined on frequent closed...
متن کاملAn Efficient Algorithm for Enumerating Pseudo Cliques
The problem of finding dense structures in a given graph is quite basic in informatics including data mining and data engineering. Clique is a popular model to represent dense structures, and widely used because of its simplicity and ease in handling. Pseudo cliques are natural extension of cliques which are subgraphs obtained by removing small number of edges from cliques. We here define a pse...
متن کاملAn Algorithm for Enumerating All Tree Matchings for Ordered Trees
We consider the problem of finding all tree matchings between two input ordered trees. If an ordered tree has internal structured variables as internal nodes, it is said to be a term tree. In this talk, we deal with the enumeration problem for tree matchings between an ordered tree and a term tree. A term tree T1 and an ordered tree T2 are given. Then, we consider the problem for finding all tr...
متن کاملAn Efficient Algorithm for Enumerating Closed Patterns in Transaction Databases
The class of closed patterns is a well known condensed representations of frequent patterns, and have recently attracted considerable interest. In this paper, we propose an efficient algorithm LCM (Linear time Closed pattern Miner) for mining frequent closed patterns from large transaction databases. The main theoretical contribution is our proposed prefix-preserving closure extension of closed...
متن کاملAn Efficient Algorithm for Enumerating Chordless Cycles and Chordless Paths
A chordless cycle (induced cycle) C of a graph is a cycle without any chord, meaning that there is no edge outside the cycle connecting two vertices of the cycle. A chordless path is defined similarly. In this paper, we consider the problems of enumerating chordless cycles/paths of a given graph G = (V,E), and propose algorithms taking O(|E|) time for each chordless cycle/path. In the existing ...
