My data has both numerical and polynominal attributes, and a numerical label.
I was originally running the chain with EvolutionaryWeighting (after a suggestion I found on this board), and it successfully returns non-identical weights. Replacing the operator with PSOWeighting, and using the default parameters, produces all zeros.
I saw no errors in the logs, and looking at the docs there don't appear to be any missing inputs. What am I missing?
