055987 in a different solution. Rounding off of results does not always work when we are considering vectors of real numbers as can be seen in Fig. 4. Clustering can be used to find a smaller number of distinct vectors. For example, we could use the centroids of the four clusters in Fig. 4 as four distinct optimization solutions. Another interesting application of rough sets in big data can be found in the attribute clustering proposal by Janusz and Slezak [7] to reduce high dimensional Fig. 4. Optimization solutions that can be grouped into four clusters 20 P.

Peters et al. [18] used supermarket data to show how the changing purchasing patterns can be modeled using rough set based dynamic clustering. Such a dynamic clustering involves creation of new clusters, deletion of obsolete clusters, and merging of clusters that are becoming indistinguishable. Ammar et al. [1,2] used a variation of dynamic clustering, called incremental and decremental clustering, to adapt to the changing nature of the data using possibilistic soft clustering. The approach was shown to be useful even for standard data mining datasets.
