Which statement is true about clustering methods? a. Fuzzy-C means is a clustering method based on an iterative methodology that assigns a set of discrete (Boolean) class membership values on the basis of the distance in feature space between a feature vector and each class centroid. b.Fuzzy-C means is a clustering method based on an iterative methodology that assigns a set of continuously valued class memberships on the basis of the distance in feature space between a feature vector and...

(a) All features are assumed to be independent (b) No features are assumed to be independent (c) All features are assumed to be independent given the class label (d) No features are assumed to be independent given the class label Give a brief explanation:
a) Why is implementing a K-means clustering algorithm multiple times with a fixed K important to do? 119 b) Why is cross-validation preferred over resubstituting as a method to measure classification accuracy?
