ARuleGUI is a graphical user interface for the apriori program. It contains a simple viewer to display the rules in a table and supports sorting them according to consequent, size, support, confidence, lift value, and additional...

Eclat is a simple application specially designed to help you find frequent item sets (also closed and maximal) with the eclat algorithm, which carries out a depth first search on the subset lattice and determines the support of item sets by intersecting...

Carpenter is a program to find closed frequent item sets with the carpenter algorithm (Pan et al. 2003), which enumerates transaction sets, in contrast to many other frequent item set mining algorithms, which enumerate item sets. Such an approach can be...

Seqwog is a command prompt application specially designed to help you find frequent sequences without gaps in their occurrences.That is, the items of the frequent subsequences must always be consecutive in the underlying transactions. There must not be...

RElim is a program to find frequent item sets (also closed and maximal) with the Relim algorithm (recursive elimination), which is inspired by the FP-growth algorithm. Basically all the work is done in one recursive function of fairly few lines of code....

JIM is a program to find Jaccard item sets with an extension of the Eclat algorithm. In analogy to frequent item set mining, where one tries to find item sets the support of which exceeds a user-specified threshold (minimum support) in a database of...

SaM is a program to find frequent item sets (also closed and maximal) with a split and merge algorithm (Split and Merge), which combines a depth-first traversal of the subset lattice with a horizontal transaction representation. The main strength of this...

FPgrowth is a program to find frequent item sets (also closed and maximal) with the fpgrowth algorithm (frequent pattern growth, Han et al 2000), which represents the transaction database as a prefix tree which is enhanced with pointers that organize the...

IsTa is a program to find closed frequent item sets by intersecting transactions (Intersecting Transactions), which is based on the insight that an item set is closed if it is the intersection of all transactions that contain it. Such an approach can be...

Sequoia is a program to find frequent sequences with unique occurrences of items and weight averaging. That is, an item may occur only once in each transaction (and thus also in each found frequent subsequence). The subsequences may contain gaps, that is,...
