Need help with word «subsume»

Hello, everybody.

The context is:
«Thus feature extraction subsumes feature selection.»

Now tell me: what is part of what?

After a 5-sec thinking, my opinion is that feature extraction is part of feature selection. Am I right?

Almost. It's the other way round - feature selection is part of feature extraction.

Ben.
