# Is feature complementarity different from feature interaction?

I am writing a conference paper in which I have a sentence like "...complementary/interactive features...". This sentence discusses features in the context of feature selection as a preprocessing step to solve a classification problem. However, given my little background in the field, I am not really sure if the two words do in fact refer to the same thing!

Can complementary features also be described as interactive ones, and vice versa? OR are "feature complementarity" and "feature interaction" totally different things?
