UCB Drift Router for Cheap-or-Expert Inference

Replace a fixed confidence threshold in cascaded inference or mixture-of-experts routing with a queue-aware UCB-DPP controller. The controller sends an input to a cheap model when its optimistic estimated success is sufficiently high and the expert backlog is large, while escalating uncertain or high-value inputs when the penalty for an error dominates congestion. This should reduce expensive-model utilization without allowing latency or escalation queues to diverge.

Graph Quotient Minibatch Coupling

Use a minibatch-level transport plan that jointly decides which source graph should be paired with which target graph and how each target should be node-aligned. This can reduce total flow-matching displacement beyond per-example matching, producing shorter and less conflicting training trajectories without modifying the architecture.

Unassembled Adaptive Cell Neural Network

Represent every mesh interface degree of freedom by one feature copy per incident cell, and apply local neural blocks directly to these cell tensors. Enforce inter-cell consistency with valence-weighted averaging only after selected layers or hierarchy transitions, avoiding repeated construction of a global sparse graph or assembled feature vector. This is suited to adaptive quadtrees, octrees, and finite-element neural operators.
