Replace a globally chosen constant learning rate with a blockwise rate calibrated to the local flatness exponent of the objective. If the local Hessian decays like \(\|x-x_\star\|^{m-2}\), choose the rate so that the predicted stationary parameter radius \(\alpha^{1/m}\) matches a prescribed exploration or optimization radius, rather than incorrectly using the quadratic rule \(\sqrt{\alpha}\).

Compress a transformer KV cache by selecting actual past tokens whose key or hidden-state columns form a stable basis for all cached tokens. Instead of retaining tokens with the largest attention scores or leverage scores independently, compute rank-revealing pivoting of the leading right-singular-vector matrix and retain its pivot columns, then evaluate attention using the representatives plus an optional low-cost residual correction.

Train a generative watermark so that its information about the payload is deliberately distributed across positions or overlapping windows instead of being concentrated in a few easily cropped tokens. The objective uses the paper's conditional information profile and the footprint-resolution lower bound to select the smallest carrier support compatible with a target crop size, while preserving generation quality outside that support.

Use a low-rank Tucker reconstruction as a structured backbone and quantize only its residual after an orthogonal rotation. The rotation preserves residual energy but redistributes it across coordinates, reducing dynamic-range imbalance and making 2- or 4-bit uniform quantization less damaging than direct quantization of the original KV tensor.

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.

Use the extreme-eigenvector marginal test to decide whether a Kronecker preconditioner is condition-optimal, rather than blindly running expensive factor refinement. If the certificate fails, construct a low-cost factor correction from the mismatch between tensor marginals of the worst-conditioned spectral states and accept it only with a condition-number line search.

Replace dense self-attention by a sparse mask on a one-dimensional or ordered token geometry, retaining local neighbors and adding long-range edges with probability proportional to distance raised to \(-(1+\sigma)\). Use \(\sigma\approx0.8\text{--}0.85\) as the initial regime because the paper finds that this range supports delocalized, GOE-like connectivity despite sparse bonds. The resulting layer has linear or near-linear attention cost while maintaining long-range paths.

Replace ordinary low-precision multiply-add accumulation in selected neural-network reductions with a two-word floating-point accumulator updated by the paper's branch-free DW-FMA network. The high word retains the main sum and the low word stores the rounding residual, improving cancellation behavior without the control-flow divergence of conditional compensated summation.

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.

Partition tokens into a rectangular grid and use Latin-square labels to define several sparse attention heads. Each head attends only to tokens sharing a row, column, or Latin label, while orthogonality guarantees that every pair of labels occurs at most once, reducing systematic blind spots and repeated collisions. The resulting masks are deterministic, reusable across examples, and can be generated without learned routing scores.

Construct a weight-tied transformer loop in which the recurrent state receives a bounded diagonal carry plus a learned block increment, rather than applying a residual identity inside the learned increment. Parameterize the carry so every channel is strictly below one, allowing many recurrent iterations without the state explosion observed with an unconstrained carry.

Route tokens to experts using Laguerre cells defined by the minimum control energy needed to move a token embedding to each expert prototype, rather than by Euclidean distance or an unconstrained learned router logit.

Use the activation singular-value spectrum to allocate a fixed zeroth-order parameter budget across layers instead of assigning the same rank everywhere. Layers with a large discarded singular-value tail receive more coefficient directions, while spectrally compressible layers use smaller adapters, preserving the gradient-relevant subspace under a global memory and query budget.
