Advances in algorithms based on CbO
Original language description
The paper presents a survey of recent advances in algorithms for computing all formal concepts in a given formal context which result as modifications or extensions of CbO. First, we present an extension of CbO, so called FCbO, and an improved canonicitytest that significantly reduces the number of formal concepts which are computed multiple times. Second, we outline a parallel version of the proposed algorithm and discuss various scheduling strategies and their impact on the overall performance and scalability of the algorithm. Third, we discuss important data preprocessing issues and their influence on the algorithms. Namely, we focus on the role of attribute permutations and present experimental observations about the efficiency of the proposed algorithms with respect to the number of inversions in such permutations.
