Influence-Adaptive Strategic Quantization

Insert a topology-controlled strategic communication layer into graph neural networks: each node maps a bounded latent scalar to either a clipped amplified signal or an interval-quantized message, with the amplification determined by how much influence the receiver exerts on the sender. Weakly influential communication channels should become aggressively quantized, while highly influential channels retain more resolution. This creates a principled variable-rate message-passing architecture…

Event-driven shared-neuron graph

Replace a conventional feed-forward block with a sparse temporal graph whose hidden units are shared across many computation paths. Each arriving message updates a shared accumulator, applies a nonlinear response, and schedules delayed messages to downstream neurons; constructive or destructive interaction emerges when multiple paths visit the same unit.

Harmonic-coordinate neural PDE ansatz

Build a complex-valued coordinate map q(x) whose components are harmonic and whose gradients are mutually null, then feed q(x) into an otherwise unconstrained neural function v. Any learned output of the form u(x)=v(q(x)) is analytically harmonic when the constraints are satisfied, so the network does not need to rediscover the Laplace structure from collocation data. This is especially suitable for two-dimensional elliptic PDEs, where q=x+iy is the canonical example.

Stoichiometric Conservation Head

Replace a network head that independently predicts coupled physical source terms with a low-dimensional rate head followed by a fixed stoichiometric map. This makes conservation of total mass or other linear invariants exact by construction and leaves the network responsible only for learning the kinetics of admissible exchange channels.

Constraint-preserving DAE neural block

Build a neural dynamical block whose hidden state contains differential variables and Lagrange multipliers, with a singular descriptor matrix enforcing constraints during propagation.

Residual-energy cross attention

Replace dense query-key attention with an adaptive cross approximation constructed from selected query and key pivot tokens. At each rank, choose the pivot pair that removes large estimated residual energy, update the residual by a rank-1 cross correction, and stop when the residual estimate reaches a target tolerance. The resulting factorization computes approximate attention using a small number of landmark interactions while adapting to the actual token distribution.

Topological Response Basis Layer

Insert a small continuous-time Markov latent module between a neural encoder and decoder, with input-dependent transition rates and a fixed library of graph topologies such as directed cycles, reversible chains, and branching motifs. The output is an observable of the stationary distribution, while a learned convex mixture over topology-specific response curves constrains the network to represent responses as combinations of interpretable nonequilibrium mechanisms.

Rotational-Twist Recurrent Layer

Replace an unconstrained recurrent matrix by a structured asymmetric circulant coupling whose Fourier modes have analytically known complex eigenvalues. A selected nonzero mode becomes a rotating attractor, providing a phase-coded recurrent state that can preserve information through oscillatory dynamics without requiring the optimizer to discover a stable spectral structure from scratch. A weak input projection and optional mode-selection loss can use the attractor as a nonlinear memory…

Electrical Response Attention

Replace unconstrained token-mixing logits by a symmetric zero-row-sum response matrix generated from positive conductances on a small auxiliary electrical network. The resulting mixer has conservation and positivity structure, while circular minors have a prescribed sign pattern associated with positive grove measurements. This is especially suitable for graph neural networks and attention variants that need stable global diffusion rather than arbitrary dense affinities.

Measure how validation forecast error grows with prediction horizon and fit exponential and Mittag-Leffler models. When the Mittag-Leffler fit is decisively better, activate a fractional-memory SSM or long-memory residual branch and use its fitted effective order to set the branch's kernel decay and horizon-loss weights; otherwise retain a conventional recurrent or finite-memory branch.

Reversible Tropical Mutation Block

Replace a conventional two-layer channel mixer in a reversible architecture with the tropicalization of two cluster mutations. For every pair of channels, the block applies sign-dependent integer shears and reflections, giving a cheap piecewise-linear transformation that is exactly invertible and requires no stored activations during backpropagation. Continuous trainable affine scale and mixing parameters can be placed around the fixed tropical core.

Shared-Private Matrix-Weighted Expert Layers

Build a multi-expert or multi-task layer whose feature channels are divided into a globally shared subspace and expert-private subspaces. Matrix-weighted message passing couples experts only through selected feature directions, while the nullspace preserves specialization; the graph-cut condition provides a concrete test that the shared channels can propagate across all experts rather than becoming disconnected islands.

Monotone Forced-Response Adapter

Separate a pretrained sequence model's passive prediction from the causal effect of an action, and learn only the latter with a compact monotone adapter. The adapter receives the current latent state and an action deviation, but its action-to-output Jacobian is constrained to have the physically correct sign, preventing intervention predictions that move opposite to the applied control.

Modes may encode safety, hardware configuration, and independent task goals.

Local Krylov-TT residual block

The block computes a short Krylov expansion, p_m(A)x = sum from k=0 to m of c_k A^k x, compressing back to a fixed TT rank after each operator application; locality is intended to prevent rank growth from scaling with the total number of tensor sites.

Controllability-Guided Low-Mode Adapter

Use a small number of learned low-mode controls and a fixed bank of Lie words to generate structured high-mode updates. This gives a parameter-efficient adapter for spectral operators or sequence models: the trainable degrees of freedom live only in the low modes, while commutator compositions provide deterministic propagation paths to larger offsets. The design is especially suitable for fine-tuning a pretrained Fourier or state-space model under a strict parameter budget.
