    This received much discussion on this n.g. a few years ago. I _think_ I
    asked a question something like "...suggestions for initialisation
    staratgies for fuzzy c-means clustering...". Search Google groups,
    perhaps something like <"fuzzy c-means" + initialisation"> or add
    "jg.campbell".

    If that reveals nothing, email me an I'll dig out a summary -- in fact a
    Java version of f.c-m that allows you to choose an initialisation method
    from those suggested; in fact, AFAIK, I posted that code to the n.g.

    Best regards,

    Jon C.
