You can say:

"it's a graph"


"it's a sparse matrix"

But the point is, it's a mapping from set A to set B.

And Bob's point is that there are other ways to model mappings, especially the kind of sparse mapping associated with human preferences among 150 choices, than as a dense matrix. Received on Wed Jan 28 2009 - 05:48:28 CET
