New learning methodology for classifiers based in Fuzzy Cognitive Maps
Propuesto por Lic. Leonardo Javier Concepción PérezResumen
Fuzzy Cognitive Maps (FCMs) are a very peculiar type of recurrent neural
networks that allow modeling complex systems in terms of concepts and causal relations.
While FCMs have proven successful in addressing simulation scenarios, their
performance in solving pattern classification problems is quite variable. Nevertheless,
the interpretability and transparency attached to these cognitive networks have motivated
researchers to improve their performance. On the other hand, some definitions and
theorems have been recently introduced to unveil the dynamic behavior in FCMs
equipped with sigmoid transfer functions. These analytic tools allow estimating bounds
for the activation value of each neuron. In this paper, we present a new learning
methodology for FCM-based classifiers, using the estimated bounds of neurons, that
leads to high prediction rates. The numerical results show that our neural classifier is
able to outperform most algorithms adopted for comparison, while remaining competitive
with the most accurate ones.
