Dynamic Ranking and Translation Synchronization

1 code implementation4 Jul 2022 Ernesto Araya, Eglantine Karlé, Hemant Tyagi

In this setup, we are given a sequence of comparison graphs $(G_t)_{t\in \mathcal{T}}$, where $\mathcal{T} \subset [0, 1]$ is a grid representing the time domain, and for each item $i$ and time $t\in \mathcal{T}$ there is an associated unknown strength parameter $z^*_{t, i}\in \mathbb{R}$.

Seeded graph matching for the correlated Gaussian Wigner model via the projected power method

no code implementations8 Apr 2022 Ernesto Araya, Guillaume Braun, Hemant Tyagi

We assume in this work that the observed pair $G, H$ has been drawn from the Correlated Gaussian Wigner (CGW) model -- a popular model for correlated weighted graphs -- where the entries of the adjacency matrices of $G$ and $H$ are independent Gaussians and each edge of $G$ is correlated with one edge of $H$ (determined by the unknown matching) with the edge correlation described by a parameter $\sigma\in [0, 1)$.

Latent Distance Estimation for Random Geometric Graphs

1 code implementation NeurIPS 2019 Ernesto Araya, Yohann de Castro

We introduce a spectral estimator of the pairwise distance between latent points and we prove that its rate of convergence is the same as the nonparametric estimation of a function on $\mathbb{S}^{d-1}$, up to a logarithmic factor.
