Sobre IBD

Os métodos de agrupamento visam obter partições homogéneas de objetos, promovendo simultaneamente a heterogeneidade entre essas partições. Todas as abordagens de agrupamento, tais como métodos hierárquicos, de partição e neuronais, têm as suas vantagens e limitações. Focamos nos métodos neuronais, pois eles superam os limites dos métodos hierárquicos e de particionamento e são as abordagens de agrupamento mais adequadas para um grande número de dados. Neste trabalho, propomos um algoritmo multi-SOM usando um critério de avaliação diferente. Assim, é necessária uma revisão das medidas de avaliação propostas na literatura. No entanto, o método multi-SOM, juntamente com sua força e eficiência na delimitação de clusters, também tem um limite na condição de parada.

    Metody klasteryzacji mają na celu uzyskanie jednorodnych podziałów obiektów, jednocześnie promując heterogeniczność między tymi podziałami. Każde podejście do klasteryzacji, takie jak metody hierarchiczne, partycjonujące i neuronowe, ma ostatecznie swoje zalety i ograniczenia. Skupiamy się na metodach neuronowych, ponieważ pokonują one ograniczenia metod hierarchicznych i party...
