KS-Adaptive Graph Halting

Use the KS ratio to decide how many message-passing layers to execute per graph or per node, rather than selecting a fixed depth. In the subcritical regime, stop once the predicted remaining effect is below a tolerance; in the supercritical regime, continue until the observed logit change becomes small or a larger budget is reached.

Geometric Feedback Compute Scheduler

Treat unresolved inference items as active threats and allocate a fixed budget of C module evaluations per round. Each evaluation has an item-dependent probability of completing the item, while the scheduler observes only completion or failure after the round. Use fair allocation when completion probabilities are unknown or nearly homogeneous, then switch to a marginal-success greedy policy as feedback estimates become reliable.

Prony Memory Bank for Linear-Time Sequence Modeling

Replace quadratic self-attention over a sequence with a bank of K auxiliary exponentially decaying states whose rates are fitted directly from the empirical autocorrelation of the sequence features. Each mode captures a distinct time scale, so the module can represent short- and long-range dependencies with O(TK) computation and O(K) recurrent memory rather than storing all previous tokens. Constrain decay rates to be positive and use the paper's extended Markovian block structure to obtain a…

Subcritical Ancestral Attention

Construct a sparse attention layer by sampling backward token histories as a continuous-time branching process rather than allowing every query to attend to every key. Each active ancestor either dies or branches into a bounded number of candidate ancestors, with branching probability controlled by a small parameter. The branch-out penalty predicts exponentially small probability of long, highly branching histories, providing a direct knob for receptive-field size and attention FLOPs.

Critical Heavy-Tail Propagation Layer

Insert a sparse heavy-tailed nonlocal mixing operator into a residual sequence, graph, or spatial network so that information can traverse distant positions without stacking many local layers. Use the critical tail exponent s = 1/2, whose truncated first moment grows logarithmically and predicts an effective propagation distance proportional to depth times log depth rather than merely depth.

Perron-Critical Sparse Routing

Model dynamic routing as a multitype branching process: an active token of type d probabilistically creates child activations of type d'. Estimate the corresponding mean offspring operator and regulate its Perron root to a target reproduction rate, typically near one. This should make adaptive-depth or recursively routed networks use sparse computation without producing either rapidly vanishing paths or uncontrolled activation explosions.

Sub-Gaussian Reachability Sparse Attention

Constrain a graph or token attention layer to behave like a row-stochastic diffusion with walk dimension \(\beta\), and choose its neighborhood radius from the paper's first-hitting-time tail bound. At propagation time \(t\), interactions with effective distance larger than \(r(t,\varepsilon)\) are removed because their total reachability probability is bounded by a prescribed error budget \(\varepsilon\).

Free-boundary neural halting

Replace a fixed confidence-threshold early-exit rule with a finite-horizon optimal-stopping policy over the model's evolving posterior confidence. The controller stops when the calibrated expected terminal error is no greater than the cost plus expected value of executing another neural block, permitting time-dependent and nonmonotone stopping regions.

Excursion-Adaptive Temporal Tokenization

Replace a uniformly sampled trajectory sequence by a binary temporal partition whose intervals are split only when the observed trajectory makes an excursion larger than a threshold. Encode one summary token per retained leaf, optionally including duration and endpoint displacement, so smooth trajectory regions receive fewer tokens while rapidly changing regions retain resolution.

Random-Batch Interaction Layer

Replace an all-pairs interaction or attention-like message field with an unbiased estimator obtained from a uniformly random partition into batches. Keep the partition fixed for \(\tau\) integration steps, then redraw it; the paper's error law predicts that too-long reuse causes a quadratic-in-\(\tau\) error accumulation, while finite-population error decreases as \(N^{-1}\).

Polylogarithmic Heavy-Tail Attention

Replace dense attention or strictly local windows with a refreshed sparse communication graph whose edge lengths follow a truncated power law. For sequence positions or image patches at distance $r$, sample edges with probability proportional to $(1+r)^{-(d+\alpha)}$; in the regime $0<\alpha<d$, repeated layers should spread information across the sequence much faster than a local window while using only $O(nk)$ edges per layer.

Risk-cost efficient frontier routing

Build a sparse expert cascade whose router uses empirical progress, uncertainty, and compute cost to construct an efficient frontier of experts. Instead of always choosing the expert with the largest immediate gain per FLOP, route different confidence states through an ordered sequence of frontier experts, allowing cheap high-variance experts early and safer or more cost-effective experts near the final decision.

Superlinear Reinforced MoE Routing

Replace one-shot softmax expert routing with a small number of synchronous routing rounds in which each token resamples an expert with probability proportional to that expert's current load raised to a power \(\alpha>1\). The resulting positive feedback rapidly creates a dominant routing basin, potentially reducing the number of active experts and communication groups at inference while retaining a controllable exploration phase through the initial round or a token-specific score factor.

Reflected Survival Routing

Replace independent binary early-exit or token-pruning decisions with a monotone randomized survival process for each token or expert route. A token can lose survival mass at each layer but cannot become active again; the model is trained with a reflected obstacle-style penalty that activates when the predicted value of continuing computation is below the value of stopping plus the compute cost. Mean-field statistics are computed over currently surviving tokens, making routing less sensitive to…

Beta-fragmented hierarchical attention

Build a binary hierarchy over tokens by recursively splitting each active block with a beta-splitting rule, then perform dense attention only inside small leaf blocks and communicate between leaves through learned summaries at internal nodes. The beta parameter controls how balanced the partition is, while the paper's maximum-depth asymptotic supplies a principled depth budget and a way to detect pathological trees.

Percolation-guided reinforced sparse attention

Tokens at intersections of selected axes receive extra cross-axis attention edges, creating a reinforced sparse graph that can transmit information across large blocks while using far fewer edges than dense attention. The mask should use light-tailed, approximately geometric spacing in both directions rather than heavy-tailed spacing in one direction.

Binomial-thinning (s,S) capacity controller

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.
