Modified Conn-Index for the evaluation of fuzzy clusterings.
Tina Geweniger, Marika Kästner, Mandy Lange, Thomas Villmann · The European Symposium on Artificial Neural Networks · 2012
We propose an extension of the Conn-Index to evaluate fuzzy cluster solutions obtained from fuzzy prototype vector quantization, whereas the original Conn-Index was designed for crisp vector quantization models. The fuzzy index explicitly takes the fuzzy assignments resulting from fuzzy vector quantization into account. This avoids the information loss which would occur if the original crisp index is applied to fuzzy solutions.
