I just read Andrew Ng's paper (/m1). Being concise and smooth in logic, Andrew's papers are always fun to read, even though I don't understand the gory details on his proofs of lemmas at the first time reading.

On the other hand, Yair Weiss's paper is more on the application of spectral algorithms in vision. It is nice review of converging progresses made in distant fields. But I just think this paper is a bit weak on the "unifying" effort. In another word, it did more pair-wise comparison but little on a common reference against which all 3 methods are compared.
