Dynamic angular synchronization under smoothness constraints
Ernesto Araya, Mihai Cucuringu, Hemant Tyagi
Given an undirected measurement graph , the classical angular synchronization problem consists of recovering unknown angles fr…
Graph Matching via convex relaxation to the simplex
Ernesto Araya Valdivia, Hemant Tyagi
This paper addresses the Graph Matching problem, which consists of finding the best possible alignment between two input graphs, and has many applications in computer vision, netwo…
Random Geometric Graphs on Euclidean Balls
Ernesto Araya Valdivia
We consider a latent space model for random graphs where a node is associated to a random latent point on the Euclidean unit ball. The probability that an edge exists bet…
Latent Distance Estimation for Random Geometric Graphs
Ernesto Araya, Yohann De Castro
Random geometric graphs are a popular choice for a latent points generative model for networks. Their definition is based on a sample of points on the Eucl…
Relative concentration bounds for the spectrum of kernel matrices
Ernesto Araya Valdivia
In this paper we study the concentration properties for the eigenvalues of kernel matrices, which are central objects in a wide range of kernel methods and, more recently, in netwo…
