    Hi,

    what is multi-dimensional scaling? Can you explain what you want to achieve? If it is that what I assume the answer is: yes.

    Cheers,

    This was also bugging me for a while, tried to solve it in RapidMiner and I think the answer is no.
    By multidimensional scaling (MDS) I mean this: http://en.wikipedia.org/wiki/Multidimensional_scaling

    For example, here is the Matlab version:
    http://www.mathworks.com/help/toolbox/stats/mdscale.html
    It has a distance matrix as an input and it maps all the points usually to 2D/3D.

    It is an old technique, but there is still active research on it. A unified solution was presented at KDD 2010:

    I think it would be a great addition to RapidMiner.
