Are features that do not co-occur with the output variable (of a complementary distribution/(-)ve point-wise mutual information) deemed irrelevant?

The fact that a feature is of a complementary distribution does not seem to be a sufficient reason to discard the feature as irrelevant; especially as they seem phenomenologically relevant.

Harmonic current can be removed from the utility by injecting negative harmonics in to the system using DSTATCOM. In the closed loop controller part you can replace conventional PI or PID controller to intelligent controllers such as fuzzy, ANN , ANFIS, Fuzzy tuned PI or PID controller.

how it will allow selective harmonic elimination? suppose I want to remove 3rd and 7th harmonic only??
