Path-complete stable routed SSM

Replace a single shared quadratic stability constraint in a routed state-space model with a path-complete family of quadratic certificates indexed by a small graph. During architecture search or training, identify bottleneck certificate nodes whose transition inequalities are nearly tight, split only those nodes, and re-solve the certificate problem. This should permit larger per-mode state transitions than a common Lyapunov matrix while retaining bounded hidden-state dynamics for arbitrary…

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.
