    On pruning techniques in map-reduce style CbO algorithms

  • Original language description

    A fundamental task in formal concept analysis is the enumeration of formal concepts. Among the fastest algorithms for this task belong algorithms which are based on Close-by-One (CbO), a tree recursive algorithm using lexicographical order of formal concepts to ensure that each formal concept is enumerated exactly once. State-of-the-art algorithms based on CbO, e.g. FCbO, In-Close4, and In-Close5, employ several techniques, which we call pruning, to avoid some unnecessary computations. However, the number of the formal concepts can be exponential w.r.t. dimension of the input data. Therefore, the algorithms do not scale well and large datasets become intractable. To resolve this weakness, several parallel and distributed algorithms were proposed. We propose four new CbO-based algorithms intended for Apache Spark or a similar programming model and show how the pruning can be incorporated into them. We experimentally evaluate the impact of the pruning and demonstrate the scalability of the new algorithms.
