Weiss begins Section 4, the discussion, with the following question: "Why do eigendecomposition methods for segmentation work?" Does he address this question anywhere in the paper? Or is this a question for future research? What is this paper supposed to be about anyway? Shouldn't a unifying view of methods based on eigenvectors of the "affinity matrix" at the very least describe what an "affinity matrix" is and why one might choose to find its eigenvectors (besides the fact that it seems to be a popular thing to do)?
