@JorisMeys In quantum field theory, one has certain regular graphs, each of which evaluates to a real number through some very complicated integral. The task is to predict that number through correlations with properties of the graph (number of cycles, cuts, etc.). For almost 2 million graphs, these numbers are freely available.
