Important Edges #26

Closed akim1 closed 9 years ago

akim1 commented 9 years ago

Along the lines of kristinmg's question, not all edges/nodes are equally important, and for instance, a node with many edges may be biologically more important than a node with one or two edges (or vice versa). In these instances, reducing the information of the graph to one or two dimensions seems more appropriate than trying to process the complete graph. What are some information that can be gleaned from using a whole graph that would otherwise would not be obtainable from using simple features?

take any 2 features. what does 1 feature tell you about the graph. what does the other. this tells you what 1 feature is missing from just one other feature. now extrapolate that to 2^n^2 features...
