Biclustering is usually referred to as the process of finding subsets of rows
and columns from a given dataset expressing a relationship. Each subset is a
bicluster and corresponds to a submatrix whose elements tend to present a
high degree of coherence with each other, that may lead to novel discoveries
regarding the objects in the dataset. This coherence leads to the possibility
of obtaining representative values for rows (subset of objects) and columns
(subset of attributes) of each bicluster. In the literature, it is usually
studied the additive coherence among elements, i.e. each element is
represented by the sum of its respective representative values. But in a given
dataset, it is also possible to find multiplicative relations, i.e. each
element being represented by the multiplication of its respective
representative values, and that may reveal distinct knowledge contained in the
objects of the dataset. So, in this paper, a swarmbased approach, named
SwarmBcluster, is adapted to find both additive and multiplicative coherent
biclusters from a dataset, in an attempt to enrich the amount of information
provided by the biclusters. Experiments are performed considering two
wellknown datasets and it is found that the multiplicative coherence
biclusters improve the quality of the data analysis and may contribute to
reduce the influence of noise.
