We introduce a new swarm intelligence based algorithm for data clustering with a kernel-induced distance metric. Previously a swarm based approach using artificial ants to optimize the fuzzy c-means (FCM) criterion using the Euclidean distance was developed. However, FCM is not suitable for clusters which are not hyper-spherical and FCM requires the number of cluster centers be known in advance. The swarm based algorithm determines the number of cluster centers of the input data by using a

Experiments were done with three data sets; the Iris data, an artificially generated data set and a Magnetic Resonance brain image data set. The results show how effectively the kernelized version of validity metric with a fuzzy ant method finds the number of clusters in the data and that it can be used to partition the data.
