Beyond Degree: Rooted Motif Signatures for Latent Position Identifiability in Graphon Models
Roland Boniface Sogan, Tabea Rebafka
Graphon estimation requires structural assumptions to address its intrinsic non-identifiability. A standard approach is degree-based identifiability, where the degree function is a…
Model-based clustering of multiple networks with a hierarchical algorithm
Tabea Rebafka
The paper tackles the problem of clustering multiple networks, directed or not, that do not share the same set of vertices, into groups of networks with similar topology. A statist…
False membership rate control in mixture models
Ariane Marandon, Tabea Rebafka, Etienne Roquain +1
The clustering task consists in partitioning elements of a sample into homogeneous groups. Most datasets contain individuals that are ambiguous and intrinsically difficult to attri…
Graph inference with clustering and false discovery rate control
Tabea Rebafka, Etienne Roquain, Fanny Villers
In this paper, a noisy version of the stochastic block model (NSBM) is introduced and we investigate the three following statistical inferences in this model: estimation of the mod…
OMP-type Algorithm with Structured Sparsity Patterns for Multipath Radar Signals
Tabea Rebafka, Céline Lévy-Leduc, Maurice Charbit
A transmitted, unknown radar signal is observed at the receiver through more than one path in additive noise. The aim is to recover the waveform of the intercepted signal and to si…
Nonparametric estimation of the mixing density using polynomials
Tabea Rebafka, François Roueff
We consider the problem of estimating the mixing density from i.i.d. observations distributed according to a mixture density with unknown mixing distribution. In contrast w…
