Clustering aims at dividing a data set into groups or clusters that consist of similar data. Fuzzy clustering accepts the fact that the clusters or classes in the data are usually not completely well separated and thus assigns a membership degree between 0 and 1 for each cluster to every datum. We introduce a robust method for fuzzy clustering based on mixtures of Gaussian Factor analyzers. We illustrate our theoretical considerations by simulations and applications to real data. A comparison with probabilistic clustering is also provided
