1. A method, comprising:
detecting, by a processing device, a set of keypoints in an input image;
generating a set of keypoint vectors, wherein each keypoint vector of the set of keypoint vectors is associated with a corresponding keypoint of the set of keypoints;
extracting a feature map from the input image;
producing a combination of the set of keypoint vectors with the feature map;
transforming the combination into a set of keypoint mapping vectors according to a predefined mapping scheme;
estimating, based on the set of keypoint mapping vectors, a plurality of importance factors associated with the set of keypoints; and
classifying the input image based on the set of keypoints and the plurality of importance factors.
