    Computation of approximate reducts with dynamically adjusted approximation threshold

    No full text
    We continue our research on dynamically adjusted approximate reducts (DAAR).We modify DAAR computation algorithm to take into account dependencies between attribute values in data. We discuss a motivation for this improvement and analyze its performance impact. We also revisit a filtering technique utilizing approximate reducts to create a ranking of attributes according to their relevance. As an illustration we study a data set from AAIA’14 Data Mining Competition.</p
