Consensus-Corrected Topology-Invariant GNN

Replace ordinary topology-sensitive message passing with scalar-gated aggregation followed by an explicit correction that aligns local node states with a graph-wide consensus component. The correction should make node embeddings less sensitive to line or edge removals while preserving local information needed for prediction. This is suitable for graph neural networks and graph-based world models exposed to changing graph sizes or sparsity patterns.

Delay-Aware Plug-and-Play Residual Capacity

Construct a residual network from independently attachable modules, but permit only a number of modules whose aggregate feedback gain lies inside a delay-dependent admissible interval. Estimate deployed end-to-end latency and each module's local Jacobian gain, then reject or bypass additional modules when the predicted delayed-loop stability boundary is crossed. This turns variable-width or depth scaling into a falsifiable control problem rather than an empirical choice.

Certified contraction implicit layer

Replace a deep feed-forward block by the fixed point z=phi(Wz+Vx+b), with the recurrent weight W constrained so that the fixed point is unique for every input. The same condition makes forward fixed-point iteration stable and makes implicit differentiation well-conditioned, allowing depth-independent memory usage while providing a measurable spectral failure boundary.

Balanced State-Order Compression

Compress each hidden layer by retaining directions that are simultaneously reachable from the observed input distribution and observable at the network output. Unlike PCA or SVD, the retained subspace is weighted by downstream task sensitivity, so high-variance but output-irrelevant directions can be removed while low-variance predictive directions are preserved.

Positive-real rational resolvent mixer

Replace an unconstrained token mixer or feed-forward residual map with a feature-conditioned rational operator whose transfer matrix is positive real on the positive orthant. Apply it through a resolvent, rather than an additive residual, so that the accretivity certificate yields a nonexpansive implicit update and suppresses activation explosions.

Automaton-Supervised Neural Policy Shield

Attach a deterministic supervisory automaton to a neural policy or sequence model and mask every event disabled by the current supervisor state. Use a short receding-horizon planner over admissible events to resolve conflicts between neural preferences and shared-resource constraints. The network scores useful actions, while the automaton supplies an exact safety layer.

Koopman Hankel Dual Autoencoder

Replace pointwise sequence reconstruction with reconstruction of overlapping past and future Hankel windows in a shared latent manifold. A first encoder compresses the delay-coordinate trajectory, while a second decoder or predictor reconstructs the future block from the latent state; training therefore penalizes representations that fit observations but do not preserve dynamical evolution.

Information-Gated Attention

Use predicted covariance reduction as a differentiable gate for selecting tokens, views, sensors, or retrieved demonstrations. The gate favors inputs with high expected information gain while accounting for acquisition cost, turning attention and data collection into active observability optimization.

Gain-Weighted Cluster Co-Design

Use small-gain diagnostics to jointly learn module normalization and a communication partition rather than imposing a fixed global spectral constraint. Clusters should be formed around high-gain feedback loops, because grouping weakly related modules cannot improve the certificate and only adds bookkeeping.

Control-Cost Laguerre MoE Routing

Route tokens to experts using Laguerre cells defined by the minimum control energy needed to move a token embedding to each expert prototype, rather than by Euclidean distance or an unconstrained learned router logit. Per-expert dual weights deform the cells so that minibatch routing follows prescribed expert capacities, giving a geometrically interpretable alternative to auxiliary load-balancing losses.

Cumulative-Control Surrogate Encoder

Use cumulative control measures as the input to a neural surrogate instead of the full sequence of control values. For a quasi-static free-boundary system satisfying the paper's average-pressure path-independence assumption, two nonnegative control histories with identical integrals up to time t should produce the same state at t, allowing a smaller training input and fewer distinct control trajectories in the dataset.

Cactus-Graph Phase Budgeting

Build neural computation graphs with explicitly phase-budgeted serial and parallel branches, treating serial compositions as SRG products and parallel residual branches as SRG sums. Allocate phase centers theta_i so that every loop or branch aggregate stays away from -1, enabling stability-aware architecture search and constructive control of branch gains.

Swarmalator Token Organizer

Augment each token or graph node with a periodic latent position x_i and phase θ_i, then evolve these variables before attention or message passing. Tokens with similar phase attract in x, while tokens with similar position synchronize in θ, producing self-organized groups without an externally specified clustering objective. The coupling strengths J and K provide interpretable controls for aggregation and synchronization, and their sweep should expose the paper's four collective regimes and…
