Replace a large flat positional-embedding table with a recursively decoded nine-way address whose child transformations contract coordinates by exactly 1/3. Encode an input position using features attached to the address prefix at several depths, guaranteeing that increasing depth produces a geometrically localized representation and that an infinite valid address cannot ambiguously represent two distinct points. This is especially suitable for 2D vision tokens, maps, point clouds, or…

Replace or augment LayerNorm on a hidden representation by a learned volume-preserving linear map that minimizes the representation cloud's spherical mean width relative to a volume proxy. The determinant constraint prevents trivial shrinking, so the module targets anisotropy and elongated activation clouds; the expected benefit is a tighter geometry that is easier to quantize or cover with a small codebook.

Replace a dense third-order channel-interaction tensor by a fixed sparse support selected through the paper's uniform-marginal infeasibility certificate. Supports with a large dual margin have an effective entropy base below the channel alphabet size, suggesting fewer independent interaction slices and cheaper contractions. Use the certificate either during architecture search or as a pruning score for an already-trained tensorized layer.

Use the signed-base expansion as a compact discrete-continuous latent parameterization for a VAE or autoencoder. A short binary sequence produces exponentially refined coordinates, while a learned Markov prior captures correlations between successive latent bits. The decoder receives the resulting bounded real coordinates instead of an unconstrained Gaussian latent vector.

Replace coordinatewise rounding of activation or embedding vectors with nearest-point quantization in a learned full-rank lattice. Learn an affine transform that makes the empirical activation region more isotropic, while regularizing the lattice covering density so it does not become inefficient as dimension grows.

Replace continuously fluctuating conditional-computation decisions with a fixed-charge (s,S) controller for the number of active experts or channel groups. If the currently provisioned capacity falls below s, activate capacity up to S; otherwise retain the current capacity, preventing repeated small routing or kernel-launch decisions. Binomial thinning models the random subset of provisioned experts or channels that are actually available after token load, dropout, failures, or admission limits.

Construct a nested sequence of representations in which each coarser representation is obtained from the previous one by a 1-Lipschitz projection. Train prediction heads at multiple scales so coarse predictions remain stable and approximately recoverable from the finer representation, enabling early exit, token pooling, and controlled multiresolution inference.

Replace part of dense token mixing with a small bank of structured permutations acting on a hierarchical token tree. Diagonal inheritance shares the same local permutation across all descendant copies, while selector words activate one connector type at a chosen level and remain inactive on the next type, providing controllable multiscale receptive fields without constructing a dense attention matrix.

Train a linear adapter between two representation spaces so that it preserves not only feature values but also the relative sparsity of sampled directions in the source representation subspace. Penalize the logarithmic spread between the largest and smallest support-size expansion ratios, preventing the adapter from making some directions dense while collapsing others. This is useful for transferring sparse features between checkpoints, aligning sparse autoencoders, or inserting a…

Replace an unrestricted collection of nested dyadic attention windows on a 2D token grid by a sparse antichain: no selected window may contain another selected window. Use the paper's exponential occupancy guarantee to control how many attention blocks reuse the same token, and add a differentiable log-moment penalty during training when exact antichain selection is relaxed. The expected benefit is bounded peak KV reuse and more predictable sparse-attention cost without discarding multiscale…

Use local split-fusion rewrites as a structured alternative to globally recomputing token clusters. A model proposes a small number of neighboring tree edits per input, accepts only valid edits that reduce a learned energy, and retains the previous hierarchy across layers or decoding steps.

Represent sequence positions as vertices on a circle and use a maximal family of mutually non-crossing d-arcs to define the allowed attention interactions. Rotate the family by d positions, or use several phase-shifted families across successive layers, so each layer has only O(N) edges but repeated layers propagate information over long distances. The geometric compatibility rule replaces arbitrary local-window or hand-designed sparse masks with a structured family whose maximality gives broad…

Replace one-step greedy landmark selection in Nyström attention or kernel compression with a restricted pairwise-lookahead rule. The lookahead is motivated by the paper's explicit obstruction: a signed triangle can make individual column gains exhibit increasing rather than diminishing returns, so the best next column need not belong to the best pair.

Attach a learnable sign to every candidate graph edge and penalize signed cycles that cannot be made simultaneously positive by vertex switching. Use the resulting frustration score to prune redundant edges before or during message passing. On planar graphs, the paper's feedback-vertex-set bound motivates interpreting a low-frustration sparse graph as one with a smaller effective cyclic core, which should reduce oversmoothing and message-passing redundancy.

Build a single-hidden-layer network whose hidden weights and biases are sampled from a non-continuous distribution supported on a dense subset of parameter space, then train only the output coefficients. The result motivates discrete or mixed-precision hidden parameters without requiring a continuous Gaussian initialization; finite-width experiments can test whether this retains accuracy while reducing hidden-layer storage and arithmetic cost.

Store quantized neural-network weights in ReRAM using GF(4)- or GF(8)-based constrained blocks rather than writing raw symbols. The encoder selects codewords whose local patterns cannot create the most damaging short rectangular sneak paths, while a decoder reconstructs the original quantized symbols after sensing. This targets persistent edge-model storage and memristor crossbar weight loading, where reducing read errors may be more valuable than the coding-rate loss.

Replace a dense or irregular binary interaction matrix in a value-aggregation layer with a signed sum of blocky masks. Each blocky mask groups a set of query rows with a disjoint set of key columns, allowing all queries in a group to reuse one summed value vector. This is most suitable for linear attention, graph message passing, or any layer where the interaction matrix is applied directly to values rather than passed through a row-wise softmax.

Replace independent categorical sampling calls with a shared exact sampler carrying a reusable uniform integer state. After sampling category X from a distribution with CDF F, retain the unused portion of the underlying random interval as a new state (Z', M'), so later samples consume residual randomness instead of requesting fresh random bits. The expected random-bit cost should approach the sequence entropy rather than paying a fixed word or byte cost per sample.
