REM-Calibrated Multi-Branch Initialization

Use the paper's inverse-temperature parameter to initialize networks containing m parallel depth-N branches. Choose branch count, depth, or an explicit aggregation scale so that beta = sqrt(2(N-1)/(n log m)) stays below the critical value sqrt(2), preventing the largest random branch from dominating the aggregate. This is applicable to residual multi-branch MLPs and other architectures whose block Jacobian is a sum of products.

Dirichlet-to-Neumann Graph Pooling

Replace a large graph submodule by a compact boundary response operator that maps boundary node features to induced boundary fluxes after the interior has been eliminated. Stack these operators recursively to obtain a hierarchical graph neural network whose coarse-level computation preserves long-range effects of discarded vertices more faithfully than average pooling or simple node clustering.
