@pelsasser Sorry for the late response. The lower-level swarming interface described by @scott here will probably give you the flexibility you need, but running those swarms is going to take some serious time and computing power. Correct me if I’m wrong, @alavin, but the SP should be able to handle in input space that is larger than the number of columns.
Since you are mentioning that you have multiple fields that might contribute to the result, I should bring up that many times in the past I’ve thought the same thing and it turned out that none of those fields were chosen by the swarming algorithm to be encoded, which means the swarming process did not think the fields contributed to a better prediction when included.
This discussion might need some details about the data your are analyzing for us to better understand how to help.
