Resolving Landmark Bottleneck

Compress a directed graph into a small set of landmark vertices while guaranteeing that every node receives a distinct restricted adjacency signature. Use these signatures as structural positional features and as the only graph-to-token interface for a graph transformer, reducing landmark-mediated connectivity from O(n^2) to O(ns).

Private spectral whitening front-end

Estimate the temporal spectrum of each sequence channel using a locally private procedure, then apply a regularized inverse-square-root spectral filter before the sequence enters attention or an SSM. The filter removes predictable low-frequency or narrow-band redundancy while avoiding unstable amplification at frequencies where the private estimate is small.
