A convex semi-nonnegative matrix factorisation approach to fuzzy c-means clustering
We propose an alternative approach to fuzzy c-means clustering which eliminates the weighting exponent parameter of conventional algorithms. It is based on a particular convex factorisation of data matrix. The proposed method is invariant under certain linear transformations of the data including pr...
