Higher-order Projected Power Iterations for Scalable Multi-Matching
Florian Bernard, Johan Thunberg, Paul Swoboda +1
The matching of multiple objects (e.g. shapes or images) is a fundamental problem in vision and graphics. In order to robustly handle ambiguities, noise and repetitive patterns in…
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…
Experimental design trade-offs for gene regulatory network inference: an in silico study of the yeast Saccharomyces cerevisiae cell cycle
Johan Markdahl, Nicolo Colombo, Johan Thunberg +1
Time-series of high throughput gene sequencing data intended for gene regulatory network (GRN) inference are often short due to the high costs of sampling cell systems. Moreover, e…
Finite-time attitude synchronization with distributed discontinuous protocols
Jieqiang Wei, Silun Zhang, Antonio Adaldo +3
The finite-time attitude synchronization problem is considered in this paper, where the rotation of each rigid body is expressed using the axis-angle representation. Two discontinu…
