An algorithm to find fragments in a set of molecules that help to discriminate between different classes of for instance, activity in a drug discovery context is presented, which results in substantially faster search by eliminating the need for frequent, computationally expensive reembeddings and by suppressing redundant search.Expand

Implementations of Apriori and Eclat are described that use several optimizations to achieve maximum performance, w.r.t. both execution time and memory usage.Expand

This paper describes a C implementation of the FP-growth algorithm, which contains two variants of the core operation of computing a projection of an FP-tree (the fundamental data structure of theFP- growth algorithm), and reports experimental results comparing this implementation with three other frequent item set mining algorithms I implemented.Expand

An implementation of the well-known apriori algorithm for the induction of association rules that is based on the concept of a prefix tree, which may be used in order to minimize the time needed to find the frequent itemsets as well as to reduce the amount of memory needed to store the counters.Expand

This paper provides an overview of the foundations of frequent item set mining, starting from a definition of the basic notions and the core task, and discusses how the search space is structured to avoid redundant search, how the output is reduced by confining it to closed or maximal item sets or generators.Expand

This clearly-structured, classroom-tested textbook/reference presents a methodical introduction to the field of CI. Providing an authoritative insight into all that is necessary for the successful… Expand

This paper proposes a definition that relies on the non-existence of equivalent ancestor embeddings in order to guarantee that the resulting support is anti-monotone and describes a method to compute the support defined in this way.Expand

We explore an approach to possibilistic fuzzy clustering that avoids a severe drawback of the conventional approach, namely that the objective function is truly minimized only if all cluster centers… Expand
