An unsupervised capacity identification approach based on Sobol' indices
Guilherme D. Pelegrina, Leonardo T. Duarte, Michel Grabisch +1
In many ranking problems, some particular aspects of the addressed situation should be taken into account in the aggregation process. An example is the presence of correlations bet…
Muticriteria decision making based on independent component analysis: A preliminary investigation considering the TOPSIS approach
Guilherme D. Pelegrina, Leonardo T. Duarte, João M. T. Romano
This work proposes the application of independent component analysis to the problem of ranking different alternatives by considering criteria that are not necessarily statistically…
Application of independent component analysis and TOPSIS to deal with dependent criteria in multicriteria decision problems
Guilherme Dean Pelegrina, Leonardo Tomazeli Duarte, João Marcos Travassos Romano
A vast number of multicriteria decision making methods have been developed to deal with the problem of ranking a set of alternatives evaluated in a multicriteria fashion. Very ofte…
Application of multi-objective optimization to blind source separation
Guilherme Dean Pelegrina, Romis Attux, Leonardo Tomazeli Duarte
Several problems in signal processing are addressed by expert systems which take into account a set of priors on the sought signals and systems. For instance, blind source separati…
A Multi-Objective Approach for Post-Nonlinear Source Separation and its Application to Ion-Selective Electrodes
Guilherme Dean Pelegrina, Leonardo Tomazeli Duarte
Blind source separation (BSS) methods have been applied to deal with the lack of selectivity of ion-selective electrodes (ISE). In this paper, differently from the standard BSS sol…
