Differentially Passive Neural Blocks

Replace selected residual, recurrent, or state-space blocks by modules whose input-output Jacobians satisfy an IODP inequality throughout a prescribed activation domain. The constraint controls incremental amplification between two trajectories without requiring either trajectory to remain near one fixed equilibrium, so it should improve robustness to changing contexts and prevent exploding long-horizon sensitivities.

Role-Filler Attention

Replace dense attention over structured object tokens with attention over role-filler tensor-product representations. A learned query specifies both a role and a filler, retrieves objects matching that binding, extracts a target role, and rebinds the extracted filler into an output object.

Generator-Flow Equivariance Training

Use discovered infinitesimal generators to create small continuous transformations of hidden states and force a neural predictor to commute with those transformations. This converts symmetry discovery into self-supervised augmentation without prespecifying a group, canonical coordinates, or hand-designed equivariant layers.

Gauge-Free Inverse OT Attention

Replace ordinary row-softmax attention with a doubly stochastic Sinkhorn attention plan W, and periodically recover a gauge-fixed pairwise cost from W using the exact double-centering identity. Use this recovered cost to initialize or regularize a structured attention score, making the attention geometry identifiable despite arbitrary query and key row and column offsets.

Holonomy-designed recurrent memory

Build a recurrent module from two finite-state factors: a normalization state and a winner-selection state. Choose or learn their coupling so that the joint transition system contains a certified composite two-cycle, giving the network a small robust memory state, while every fixed-input generator still collapses most states toward attractors. The module can be embedded in a continuous RNN using soft state assignments during training and straight-through discretization for algebraic auditing.

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.

Correlation-Exponent-Safe Weight Initialization

Initialize each row of a neural weight matrix as a stationary correlated Gaussian process instead of using independent entries, but constrain its correlation tail to remain on the finite-fourth-moment side of the transition. This creates controllable structured spectra while avoiding the heavy-edge regime predicted for correlations slower than \(t^{-1/2}\).

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 regularizer is invariant to arbitrary local changes of latent representation frame, encouraging path-consistent relational features without requiring all edges to share one global coordinate system.

A parameter group is pruned when its Fisher contribution is small or its sensitivity is nearly collinear with other groups, producing a compact neural ODE without relying only on parameter magnitude.

Train a cheap shared multi-task probe briefly, extract one semantic embedding per task, and use density-based clustering to determine which tasks should share a neural trunk. After clustering, replace the globally shared trunk by one trunk per discovered cluster, with task heads remaining separate; this preserves cooperation among related tasks while isolating destructive task interactions.
