Differentiable Physics-Equilibrium Projection

Use a neural network to predict an operating point or latent state, then pass it through a sparse differentiable implicit layer that solves governing nonlinear equilibrium equations. This replaces soft physics penalties with an exact or tightly solved equality projection and can be combined with primal-dual inequality handling and deterministic restoration.

Detailed-Balance Graph Transport Layer

Replace an unconstrained graph residual update with a reversible master-equation update on a nonnegative latent mass vector. Each edge transfers mass in two directions with rates tied by detailed balance, so the layer preserves total mass, preserves nonnegativity under an appropriate discretization, and relaxes toward a learnable equilibrium while dissipating a specified free energy. This is suitable for iterative graph inference, diffusion-like architectures, and probability-valued hidden…

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.

Nilpotent BGG Neural Complex

Replace an unconstrained stack of learned vector-field or tensor-field maps by a short neural complex whose fixed differential operators satisfy D_{k+1}D_k=0. The network predicts potentials or quotient representatives, making curl-of-gradient, divergence-of-curl, compatibility, and gauge constraints exact rather than penalty-based.

Envelope-Max Neural Operator

Build each one-step operator as a maximum over a compact set of learned or discretized action branches, with a branch-dependent penalty. This directly imports the envelope structure used for nonlinear semigroups and gives a neural architecture suited to HJB equations, robust prediction, and stochastic control under model uncertainty.

Conservative Parallel-Edge Decomposition

Represent a multi-input interaction by several single-input edge channels and enforce conservation only after their signed contributions are summed at the vertices. This provides a neural architecture for composite interactions in which different channels have different drivers, while preventing the node update from inventing or destroying net internal flow.

Topological Fluctuation Graph Layer

Replace a deterministic graph propagation layer by a stable stochastic linearized latent dynamics whose frequency-resolved covariance matrix defines spectral bands. Train or initialize the graph operator so that a selected covariance band has a nonzero Chern number and remains separated by a measurable spectral gap, producing representations that are robust to local perturbations and can support boundary-localized responses.

Equation-addressable equilibrium layer

Build a recurrent or implicit neural layer from a bipartite graph containing variable nodes and equation or mechanism nodes, rather than a directed graph containing only variables. The forward pass solves all mechanism residuals simultaneously, while an intervention replaces one selected equation and fixes its target variable; this distinguishes interventions that impose the same value through different mechanisms. The resulting module is suitable for equilibrium world models, differentiable…

Weighted Resolvent-Equivariant Attention

Add a weighted reflection symmetry to an attention or graph-propagation matrix instead of requiring ordinary permutation equivariance. For paired positions or graph nodes related by an involution, penalize the failure of the propagation operator to commute with the weighted reflection; this makes all geometric multi-step propagations symmetry-compatible. The method is suitable for data with mirror, reversal, paired-agent, or left/right structure where the two sides have unequal importance…

GECC-Gated Loop-Aware Message Passing

Construct order-n generalized edges from intersections of local ego-subgraphs and use their overlap statistics to correct ordinary one-hop aggregation. A learned gate should activate the correction only when local generalized-edge closure is high, because dense but internally inconsistent overlaps are precisely where naive loop corrections can become unreliable.

Symmetry-Preserving Flow Layer

Construct hidden dynamics from permutation-equivariant vector fields and impose antisymmetry through an explicit antisymmetrizing readout. This prevents optimization from learning multiple equivalent copies of the same configuration and makes forbidden symmetry violations exactly zero, rather than merely penalizing them. The design applies to set models, particle systems, graph networks, and architectures handling unordered tokens.

Persistent Spectral Noise for Recurrent GNNs

Modify a recurrent message-passing GNN so that every propagation step adds fresh independent Gaussian noise to every node and feature channel. Unlike dropout or a one-time perturbation, the noise remains active throughout the recurrence and creates a nonzero stationary graph-frequency energy floor, preventing long-horizon node representations from converging to the constant-node subspace.

Equilibrium-Coordinate Neural Operator

Build a neural PDE surrogate that predicts changes in equilibrium variables rather than changes in conservative state variables. The network receives the local state and geometry, predicts an equilibrium-coordinate increment, and subtracts the network output evaluated at a reference equilibrium, forcing the reference state to have exactly zero learned residual.

Noise-Induced Compact-Support Neural Field

Replace ordinary dropout or soft sparsity penalties on a nonnegative spatial or token activation field with sublinear multiplicative stochastic dynamics. The field receives local diffusion or graph smoothing, while noise amplitude u^gamma vanishes at zero but is relatively strong near zero; this creates an absorbing zero state and may produce exact contiguous inactive regions. The module is suitable for feature maps, graph-node fields, token routing scores, or continuous neural operators.

Network-Respecting Controllability Regularizer

Penalize approximately invariant collections of node subspaces that receive little signal from the input, so the learned latent dynamics cannot hide useful information in unreachable subnetworks. A dual output-side penalty can prevent predictive information from becoming confined to…

Connected Collision Energy Latent Dynamics

Construct a graph-based latent state whose velocities evolve through free-flight updates and pairwise elastic collision operators. Each collision operator is orthogonal, so total latent kinetic energy is exactly conserved; a connected interaction graph is intended to eliminate unwanted component-wise polynomial invariants and improve long-horizon stability.

Bounded-Influence Hyperbolic Pooling

Each token contributes a unit tangent direction multiplied by \(\tanh\) of its hyperbolic distance from the candidate, so distant outliers cannot dominate the pooled representation while nearby, geometrically consistent tokens still determine it.

For a binary feature channel, the layer computes the probability of a positive coarse feature from the number of positive fine features, samples or relaxes the resulting Bernoulli variable, and learns only a constrained scalar rather than an unconstrained pooling kernel. The same construction can be applied independently to channels or to graph…

Introduce a binary mask over candidate neural connections or graph interactions and constrain the active subgraph to be a forest, mimicking the tree-packing configurations of the FA K=2 model. Anneal a chemical-potential parameter controlling the number of active edges; near a critical value, the mask may spontaneously favor one of two graph parities or channel groups, creating structured specialization rather than unstructured pruning.
