Fuzzy Economic Review: Volume 24, Number 1, 2019
DOI: 10.25102/fer.2019.01.03

In this paper we propose an operationalization of a multidimensional vulnerability to poverty index, with the objective of overcame the dichotomy of poverty measurements such as the poverty line and unsatisfied basic needs, which fails to represent socioeconomic restrictions of focalized groups. With the information obtained through a survey made…

Fuzzy Economic Review: Volume 24, Number 2, 2019
DOI: 10.25102/fer.2019.02.02

In this paper we use a real-coding Genetic Algorithm to evolve three different architectures of Fuzzy Wavelet Neural Networks (FWNNs) and to compare their performances when predicting financial time series (stock exchange indexes) by means of NARX( ) models. FWNNs are designed by hybridization of Neural Networks, Fuzzy Inference Systems…
