A Weighted Sum Validity Function for Clustering with a Hybrid Niching Genetic Algorithm

, 2005
Clustering is inherently a difficult problem, both with respect to the construction of adequate objective functions as well as to the optimization of the objective functions.

Remote sensing land-cover change in Port Elizabeth during South Africa's democratic transition

South African Journal of Science, 2012
Urban population increase has caused significant urban landscape transformation globally. Before 1994, South Africa's highly regulated urban growth was shaped by the restrictive Prevention of Illegal Squatters Act of 1951.

(A) ADC, CBF maps at 30, 90, 120, 150, 180 mins and 48 hrs post-occlusion, ISODATA clustering results (determined using 30-min ADC and CBF) and T2 maps 48 hrs post-occlusion (day-2) of vehicle- and MB-treated rats subjected to 60-mins MCAO are shown.

, 2013
ISODATA determined core (red) tissue volume was used as the initial lesion volume. Final infarct volume was determined based on day-2 T2 maps using the threshold method.

Low-carbon economic dispatch based on improved ISODATA scenario reduction for wind power in IES

电力工程技术
As wind power integration increases, its unpredictability challenges the integrated energy system (IES). A low-carbon, economic dispatch method for IES using an enhanced wind power scenario reduction algorithm is introduced in this paper.

Clasificación de datos: implementación de un algoritmo clustering difuso.

Tecnología en Marcha, 2016
El enfoque tradicional (crsip) de la clasificación de datos por medio de particiones usando técnicas del análisis cluster exige que los subconjuntos obtenidos sean mutuamente excluyentes, lo cual, por el tipo de información que se usa en áreas como ...
