A wildlife оrgаnizаtiоn hаs 20,000 unlabeled camera-trap images but can affоrd to manually label only 100 images. The images contain animals such as deer, bears, and foxes. The team first applies K-means clustering with k = 100 to group visually similar images. Which approach best uses K-means for semi-supervised learning?
