Hi Steve, thanks a lot, I will haev a look at the kernel appraoch ,that looks promising. I will first have to study the theory behind before I use it, I guess. Cheers M. On 10/21/2010 5:42 PM, Steve Lianoglou wrote: Hi, On Thu, Oct 21, 2010 at 9:42 AM, Martin Tomkomartin.to...@geo.uzh.ch

[R] SVM classification based on pairwise distance matrix

2010-10-21 Thread Martin Tomko
Dear all, I am exploring the possibilities for automated classification of my data. I have successfully used KNN, but was thinking about looking at SVM (which I did nto use before). I have a pairwise distance matrix of training observations which are classified in set classes, and a distance

Hi Steve, tahnks for the hints and clarifications. Unfortunately, I will not be able to use the approach you suggest, The distances I generate are distances between VERY large matrices (say 10x10 and more) each of different dimensions (not necessarily square either), and there is no
