Feature Ranking negative values

[Andrew Rodriguez]

Hi,

I noticed that the Feature Ranking shows negative values. How should I interpret them?

Thanks

Hello Andrew,
negative values can appear only for ordered input in Relative Relevance. They mean that that variable is “inversely correlated“ with a particular output value. In other words, rules with that output often contain “<=” inequalities for that input. Of course vice versa for positive relevances.

Have a nice day!
