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.
Use an online estimate of the positive feedback gain among logits, routing probabilities, and representations to adjust the softmax temperature. Increase temperature when the estimated cyclic gain approaches the instability regime, preventing exponential amplification and router collapse without globally weakening all layers.
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.
Replace an explicit attention step by an implicit Euler step that solves a proximal subproblem involving the Hopfield energy. The new state is evaluated inside the softmax self-consistently, which makes the method less sensitive to large step sizes and can prevent explicit attention from overshooting or tunneling between attraction basins.
Add a causal memory branch whose lag-response function is represented by a Bernstein polynomial with coefficients constrained to produce a nonnegative, decreasing, convex kernel. The branch aggregates past hidden states using this kernel, giving the model a learnable long-memory profile while preventing oscillatory, negative, or increasing historical influence.
Add a training-time regularizer that keeps the empirical joint covariance of hidden activations on multiple inputs close to the recursively predicted NNGP covariance. The regularizer targets the finite-width fluctuations quantified by the Wasserstein result, and is particularly appropriate for recurrent networks and attention blocks with shared weights, where hidden states at different positions or time steps are statistically coupled.
Replace coordinate-wise mean pooling of metric-valued items with a finite representation of their free integral. Each item x in a pointed metric space M is represented through evaluations of learned Lipschitz probes, and the pooled feature is the weighted integral of those probe values. A dual Lipschitz critic estimates the free-space norm of differences between pooled groups, making the representation sensitive to metric geometry while remaining permutation-invariant.
Add a pseudo-determinant-based connectivity objective to a neural model that predicts graph edge weights, attention adjacency, or sparse routing links. Maximizing the Laplacian pseudo-determinant rewards many globally distributed spanning trees, discouraging disconnected or bottlenecked learned graphs without requiring a discrete connectivity constraint.
