Thanks for mentioning the paper, this comes close to one of my topics of interest, spectral graph theory. Although quite an interesting subject (I can see myself easily being drawn to the subject), I wonder if there has been any attempts to understand or study the topological structure at the heart of algorithms that are used for learning or natural language processing/parsing. I am quite curious and eager about these methods so if you happen to know of a paper or reference please let me know.
