What is OverlapSimilarity

Legacy User

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)
