Hi,

I've just tried some similarity measures on a special dataset and the OverlapSimilarity yielded the best results. Now I'm wondering how this similarity measure works, I couldn't find any info about it. Does someone know about this OverlapSimilarity?

thanks,
Chris

    Hi Chris,
    this is a simple numerical matching. it works this way (formulated in pseudo code): 

    for (0 <= i < number of dimensions)
       wx = wx + point1
       wy = wy + point2
       wxy = wxy + min(point1, point2)
    }
    return wxy / min(wx, wy)
    Greetings,
      Sebastian
