i must use the relevance feedback for skin lesion images to select the relevant and irrelevant patterns. can i do that? and how?
could you please correct me if i am wrong:
the non dscriminative features: are the common features between 2 classes or more.
the dscriminative features: are the uncommon features between 2 classes or more.
what is the difference between the most discriminative and the most dominant feature?
Thank you in advance.
Hi,
I'm not sure about relevance feedback, but the "most discriminative" feature should be a feature that can be used to help tell the deference between the target classes. The "most dominant" feature would be the one that occurs the most. The most dominant may not be the most discriminative, for instance in document classification the most dominant feature, in a bag-of-words representation, maybe stop words like "the", "and", "it", but these are not discriminative as most documents will have them, whereas the feature "tennis" may be highly discriminative in telling whether a document is about the game of tennis, but may occur less often than the stop words.
