The fuzzy k-modes (FKM) is a popular method for clustering categorical data. However, the main problem of this algorithm is that it is very sensitive to the initialization of primary clusters, so inappropriate initial cluster centers lead to poor local optima. Another problem with the FKM is ...
In the fuzzy k-modes clustering, there is just one membership degree of interest by class for each individual which cannot be sufficient to model ambiguity of data precisely. It is known that the essence of a multivariate thinking allows to expose the inherent structure and meaning revealed ...

The positive integers \(d_y\) and \(d_{ui}\) are the corresponding maximum lags for y(k) and \(u_i(k)\), respectively. The vectors Y(k) and \(U_i(k)\), \(i = 1,\dots ,p\), are fixed once the modelling framework is determined. (ii) Regressor: $$\begin{aligned}...

The uncertainties associated with multi-area power systems comprising both thermal and distributed renewable generation (DRG) sources such as solar and wind necessitate the use of an efficient load frequency control (LFC) technique. Therefore, a hybrid version of two metaheuristic algorithms (arithmetic...
In order to search for appropriate fuzzy membership matrices which can minimize the fuzzy objective function, we present a hybrid genetic fuzzy k k mathContainer Loading Mathjax -Modes algorithm in this paper. To circumvent the expensive crossover operator in genetic algorithms (GAs), we hybridize...
