The first scheme is based on the spatial locality of feature vectors corresponding
to similar images. Learning is effected by modifying the query vector to incorporate the
positive examples. The second scheme is based on “distorting” our view of the feature space. An
new similarity distance between an image and the query is learned from the relevance feedback.
