    Shared By: MISTY DAVIES

    A script that finds the Dunn Index for a given clustering

  • Normalization Scripts

    An Algorithm, Aerospace Simulation Clustering Experiments - 12 years, 9 months ago

    Shared By: MISTY DAVIES

    Scripts that perform normalization. They assume that you will be doing a GMM version of EM, but should be useful for many kinds of normalization.
