SpletThe curse of dimensionality is a well known but not entirely well-understood phenomena. Too much data, in terms of the number of input variables, is not always a good thing. ... Splethowever, on the one hand, it suffers from the curse of dimensionality, and on the other hand, sometimes the available features may be of different forms and it is hard to lump them together. So a more commonly used strategy is to train different SVM classifiers using different features and then combine the outputs of these classifiers. dr amy holmes fresno ca https://ninjabeagle.com
