Abstract

Recently, the importance of computational intelligence methods based on lattice theory has been increasing since many classes of information granules such as fuzzy sets, intervals, interval-valued and intuitionistic fuzzy sets, etc., represent lattices. In particular, we developed the morphological perceptron with competitive learning (MP/CL) in order to solve classification problems in a lattice that corresponds to a product of chains that are endowed with an additional algebraic structure.In this project, our goal is to develop new (fuzzy) neurocomputing models for applications in classification and regression problems in more general lattices that are possibly equipped with an additional algebraic structure. To this end, we will resort to a decomposition theorem by Banon and Barrera, which states that any mapping between complete lattices can be written in terms of elementary morphological operators, in order to obtain an suitable mapping for a given supervised pattern recognition problem. Subsequently, we intend to express the morphological operators corresponding to the respective mapping in terms of certain convolutions that allow for the definition of weights of a morphological neural network. In this manner, we wish to achieve an adequate generalization performance of the resulting neuralnetwork.
