A state-space approach to sparse dynamic network reconstruction
Zuogong Yue, Johan Thunberg, Lennart Ljung +1
Dynamic network reconstruction has been shown to be challenging due to the requirements on sparse network structures and network identifiability. The direct parametric method (e.g.…
Continuous time Gaussian process dynamical models in gene regulatory network inference
Atte Aalto, Lauri Viitasaari, Pauliina Ilmonen +2
One of the focus areas of modern scientific research is to reveal mysteries related to genes and their interactions. The dynamic interactions between genes can be encoded into a ge…
High-dimensional Kuramoto models on Stiefel manifolds synchronize complex networks almost globally
Johan Markdahl, Johan Thunberg, Jorge Goncalves
The Kuramoto model of coupled phase oscillators is often used to describe synchronization phenomena in nature. Some applications, e.g., quantum synchronization and rigid-body attit…
A Lifting method for analyzing distributed synchronization on the unit sphere
Johan Thunberg, Johan Markdahl, Florian Bernard +1
This paper introduces a new lifting method for analyzing convergence of continuous-time distributed synchronization/consensus systems on the unit sphere. Points on the d-dimensiona…
Synchronisation of Partial Multi-Matchings via Non-negative Factorisations
Florian Bernard, Johan Thunberg, Jorge Goncalves +1
In this work we study permutation synchronisation for the challenging case of partial permutations, which plays an important role for the problem of matching multiple objects (e.g.…
Towards Almost Global Synchronization on the Stiefel Manifold
Johan Markdahl, Johan Thunberg, Jorge Goncalves
A graph is referred to as -synchronizing if, roughly speaking, the Kuramoto-like model whose interaction topology is given by synchronizes…
