You can say:
"it's a graph"
or
"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
