Recovering Hölder smooth functions from noisy modulo samples
Michaël Fanuel, Hemant Tyagi
In signal processing, several applications involve the recovery of a function given noisy modulo samples. The setting considered in this paper is that the samples corrupted by an a…
An iterative clustering algorithm for the Contextual Stochastic Block Model with optimality guarantees
Guillaume Braun, Hemant Tyagi, Christophe Biernacki
Real-world networks often come with side information that can help to improve the performance of network analysis tasks such as clustering. Despite a large number of empirical and…
Dynamic Ranking with the BTL Model: A Nearest Neighbor based Rank Centrality Method
Eglantine Karlé, Hemant Tyagi
Many applications such as recommendation systems or sports tournaments involve pairwise comparisons within a collection of items, the goal being to aggregate the binary outcome…
Clustering multilayer graphs with missing nodes
Guillaume Braun, Hemant Tyagi, Christophe Biernacki
Relationship between agents can be conveniently represented by graphs. When these relationships have different modalities, they are better modelled by multilayer graphs where each…
An extension of the angular synchronization problem to the heterogeneous setting
Mihai Cucuringu, Hemant Tyagi
Given an undirected measurement graph , the classical angular synchronization problem consists of recovering unknown angles from a collection of noisy…
