New method recovers Bethe Hessian eigenvectors in stochastic block models

By PulseAugur Editorial · [1 sources] ·

A new paper published on arXiv details a method for recovering outlier eigenvectors of the Bethe Hessian within the Kesten-Stigum regime of the stochastic block model. This technique extends previous recovery guarantees to scenarios with any fixed common expected degree greater than one, matching the performance of non-backtracking spectral methods. The approach involves identifying recursive formulas for negative outlier eigenvalues and constructing approximate eigenvectors using the limiting Poisson tree and its Green's function. AI

    Bethe Hessian Recovery through the Kesten-Stigum Regime

    arXiv:2610.41802v1 Announce Type: cross Abstract: We show that outlier eigenvectors of the Bethe Hessian achieve weak recovery in the stochastic block model down to the Kesten-Stigum threshold, for every fixed common expected degree $d>1$. This extends previous recovery guarantee…
