Gaussian mixture model and contour plots

Hi,

are there nodes available to:

  1. Cluster data using Gaussian mixture models?
  2. Generate contour plots from a probability density functions?

Thanks for any pointers,

Jan

 

Hi Jan,

I think that I'm correct in saying that there aren't KNIME native nodes to do this. But it should be possible to do both using the KNIME R or Python integration.

For 1, I think that this would be a start: https://cran.r-project.org/web/packages/EMCluster/EMCluster.pdf

For 2, I think that this is what you want: http://stackoverflow.com/questions/23437000/how-to-plot-a-contour-line-showing-where-95-of-values-fall-within-in-r-and-in

Hope that helps.

Best,

Jon
