how to do the 1st step in Non-metric MultiDimensional Scaling using Kruscal-Shepherd Algorithm?
I met a problem in implementing non-metric multidimensional scaling. When first initialize the 2d coordinates(x,y) (which will be adjusted later), does it matter if I use a random() to give them a random value? At first I used multidimensional scaling to initialize it, using a method called ClasscalScaling from mdsj.jar. Then I used a random to give it initial value.
The two ways have VERY different results:
mds initialized:
random() initialized:
So Why is that? and which is right?
