Add an auxiliary prescribed-performance observer to a recurrent or state-space neural network so that latent prediction errors are estimated from observable output residuals rather than relying only on backpropagation through long histories. The observer uses a transformed normalized innovation and gains that change with the desired error envelope, allowing fast early correction without permanently using a large unstable gain. It can operate online during inference or provide an auxiliary…

Parameterize a generative or density-evolving model as a composition of diffeomorphic optimal-mass-transport maps rather than unconstrained residual layers. Each layer transports one smooth positive density to another through a learned squared-distance OT map, while compositions provide a principled universal family for transformations connected to the identity.

Wrap a neural policy or sequence-model controller with an online-estimated ultra-local model of a scalar safety output, such as distance-to-obstacle, queue length, battery margin, or constraint slack. Estimate the unknown drift and control effectiveness directly from recent observations, then impose a robust control-barrier constraint that subtracts an empirical uncertainty envelope before allowing the neural action.

Use a projected dual variable as a feedback controller for terminal feasibility rather than selecting a fixed penalty coefficient. The multiplier increases after infeasible batches and decreases after feasible batches, with an explicit cap and drift-balance diagnostic that detects whether the policy-dual loop is stable.

Replace a conventional whitening transform with a constrained whitening layer that minimizes cross-channel covariance while requiring every output channel to remain correlated with its designated input channel by at least a threshold \(\rho_{\min}\). The layer exploits the orthogonal freedom in whitening to find a rotation that preserves channel identity instead of arbitrarily mixing features. It can be inserted before an MLP, convolution, or attention projection and compared directly against…

Use the estimated distance to a saddle-node ghost as an inference-time controller for recurrent or neural-ODE computation. Far from a fold, take large integration steps or update only the fast state; near the fold, reduce the step size or allocate extra recurrent evaluations because the state is expected to linger and become sensitive to small parameter changes.

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…

Construct a nonuniform diffusion timestep grid from an empirical local discretization-error density instead of using uniform time spacing or a fixed hand-designed schedule. The optimal allocation places shorter intervals where the score or posterior mean varies rapidly and longer intervals in regions where the reverse vector field is smooth.

Augment each recurrent or state-space hidden channel with a two-dimensional oscillatory state and periodically compute a pseudo-phase from its Cartesian coordinates. Use sparse event-triggered feedback to reduce the squared phase order parameter, preventing hidden channels from synchronising while avoiding the computation and communication cost of continuously recomputing the control signal. The controller acts as a tangent rotation of each two-dimensional hidden state, changing phase diversity…

Replace unconstrained residual blocks by a nonautonomous linear backbone plus a learned nonlinear perturbation, and constrain the perturbation gain using the Green operator of the backbone. The resulting network can contain both contracting and expanding channels, but the accumulated response of the perturbation remains bounded when its Green margin is below one. A differentiable or periodically updated estimate of this margin becomes both an architecture constraint and a training monitor.

Prune redundant attention heads using separate similarity scores for sink behavior and content routing. Two heads are considered safely redundant only when their normalized content compositions are close in Aitchison distance and their sink-mass trajectories are also close, avoiding pruning decisions dominated by a shared sink token.

Distill a teacher's attention into a student by matching sink mass and the normalized content distribution as separate targets rather than applying one KL divergence to the entire attention row. Use the Aitchison distance on the content composition, which compares relative token allocation and prevents a large common sink probability from overwhelming differences between content tokens.

Make a neural network predict a positive Gaussian-mixture representation of the distribution function rather than independent values on a momentum grid. Use the mixture parameters inside a differentiable Boltzmann collision operator, so training directly enforces the interaction mechanism and exposes the relaxation spectrum responsible for ballistic-to-hydrodynamic crossover.

Replace fixed-parameter unrolled Douglas–Rachford iterations in a differentiable convex optimization layer with a causal controller that adapts relaxation and objective-drive strength from the current residuals. The controller should accelerate early progress while enforcing admissible parameter ranges, so every individual block remains a stable relaxed splitting map rather than an unconstrained learned optimizer.

Build a Bloch-conditioned neural model whose periodic-factor representation transforms covariantly when the supplied Bloch wavenumber is shifted by a reciprocal lattice vector. Either canonicalize q to the first Brillouin zone or augment training with mathematically paired examples whose outputs differ by the exact phase gauge. This prevents the network from learning inconsistent predictions for physically identical Bloch modes.

Turn the latent substrate into a persistent computational workspace for sequential inputs: each new observation is written into a designated subspace, processed by the same local rule, decoded, and then selectively retained or reset. This creates a compact recurrent model whose state can accumulate algorithmic information across a stream without expanding the parameter count.

Replace a stack of independently parameterized residual or MLP blocks with a small latent grid or vector repeatedly updated by one shared transition rule.
