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 nodes into lists referring to the same item. The search is carried out by projecting the prefix tree, working recursively on the result, and pruning the original tree. Since version 1.2 this implementation also contains the alpha-pruning of the FP-Bonsai techniques.

Carpenter 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 hi
Sequoia 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,
IsTa 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 hi
ARuleGUI 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 evaluation.
MoSS MoSS is a program to find frequent molecular substructures in a database of molecule descriptions. The algorithm is based on the Eclat algorithm for frequent item set mining. Apart from the default MoSS/MoFa algorithm, this program contains the gSpan algor
Eclat 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 tr
RElim 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. Fe
