CCF 2026: Sinkhorn-Knopp Presentation Cost Tracks Matrix Density, Not a Fixed Iteration Count

Sinkhorn-Knopp doubly-stochastic normalization at a fixed iteration count wastes compute on dense matrices and under-serves sparse ones, measured directly.

Introduction

Sinkhorn-Knopp (SK) is the standard way to push a matrix of positive numbers toward doubly stochastic: alternately normalize every row, then every column, and repeat. It shows up across manifold-constrained hyper-connections (mHC, arXiv:2512.24880) and other neural-network mixing schemes as a fixed 20-iteration budget. This gist measures what that fixed budget actually buys, at 5/10/20/50 iterations, on two synthetic matrix regimes chosen to sit on either side of the density phase transition He (arXiv:2507.09711) identifies for Sinkhorn-Knopp convergence. In CCF, SK-style normalization is used only as a gauge/presentation step, never as the causal trust-transfer update itself, which is a separate quotient-affine contraction (QAC) step. This

CCF 2026: The Runtime Trust Certificate Floor — Telling a Real Signal From Rounding Noise in Autonomous-Agent Trust Verification

A runtime trust certificate floor for autonomous agents: a per-step, dynamic finite-precision threshold that separates a real loss-of-contraction signal from machine rounding noise. Real Rust benchmarks across f64/f32/fixed-point.

Introduction

Every runtime trust certificate for an autonomous agent eventually runs into arithmetic. As a trust value homes in on its target, the per-step change shrinks — until it's smaller than the rounding error of the computer making the change. At that point the residual you measure is noise, not signal. Hard-code a single

CCF 2026: Elder Care Robot Trust — Geometric Action Gating That Cannot Over-Trust a Confused Person

A care robot must do less exactly when an elder is most vulnerable. CCF derives action authority from a geometric trust gate with a runtime certificate — and proves zero over-trust in simulation.

Introduction

Elder care robot trust is the safety problem nobody likes to name: a socially assistive robot that keeps acting on a stale, optimistic relationship estimate even as the person it serves becomes confused, distressed, or unable to consent. Reviews of social robots for people living with dementia keep flagging the same
