DESCRIPTION:Comparison of graph structures is a frequently enc
 ountered problem across a number of problem domain
 s. Comparing graphs requires a metric to discrimin
 ate which features of the graphs are considered im
 portant. The spectrum of a graph is often claimed 
 to contain all the information within a graph\, bu
 t the raw spectrum contains too much information t
 o be directly used as a useful metric. In this pap
 er we introduce a metric\, the weighted spectral d
 istribution\, that improves on the raw spectrum by
  discounting those eigen-values believed to be uni
 mportant and emphasizing the contribution of those
  believed to be important.\n\nBio: Damien Fay rece
 ived a BEng in electronic engineering from Univers
 ity College Dublin in 1995\, a masters from Dublin
  City university in 1997 and a PhD in time series 
 forecasting from Dublin City university in 2003. F
 rom 2003 to 2007 Damien lectured in the mathematic
 s department at the National University of Ireland
 \, Galway. In October 2007 he joined the NetOS gro
 up at the Computer Laboratory\, Cambridge as a res
 earch associate with Andrew Moore. His current int
 erests are quite varied ranging from time series a
 nalysis for engineering and financial applications
  to graph theory applied to computer networks.\n
