The paper supplies a sharp feasibility constraint between lower-order and higher-order clique densities, expressed through the composition of Lovász–Simonovits density functions. Its transferable asset is that the theorem applies directly to weighted graphs, where clique densities are differentiable multilinear polynomials of soft edge weights and node weights. This can become a differentiable structural regularizer for graph generators or graph-valued neural networks: whenever a model predicts many soft s-cliques, it should be penalized if its predicted t-clique density falls below the mathematically unavoidable minimum. The most practical first target is s=2, t=3 on small graph generation tasks, where the required statistics are cheap and the regularizer has a clear falsifiable effect on motif consistency.
Add a differentiable penalty to a graph generator or graph predictor when its soft higher-order clique density violates the sharp lower bound implied by its lower-order clique density. The regularizer encourages generated graphs to have mathematically consistent motif statistics without hard-discretizing the predicted adjacency matrix.
