Subgraph Matching via Partial Optimal Transport
Wen-Xin Pan, Isabel Haasler, Pascal Frossard
In this work, we propose a novel approach for subgraph matching, the problem of finding a given query graph in a large source graph, based on the fused Gromov-Wasserstein distance.…

Multi-frequency tracking via group-sparse optimal transport
Isabel Haasler, Filip Elvander
In this work, we introduce an optimal transport framework for inferring power distributions over both spatial location and temporal frequency. Recently, it has been shown that opti…

Mean field type control with species dependent dynamics via structured tensor optimization
Axel Ringh, Isabel Haasler, Yongxin Chen +1
In this work we consider mean field type control problems with multiple species that have different dynamics. We formulate the discretized problem using a new type of entropy-regul…
