Speaker:Julius Lohmann JSPS International Research Fellow, Institute of Science Tokyo Title: Dynamic inverse problems regularized with Wasserstein-1 transport Julius Lohmann JSPS International Research Fellow, Institute of Science Tokyo

Abstract: The (classical, balanced) Wasserstein-p distance can be used as a measure of how close a source and sink mass distribution (with equal mass) are. In recent years, the Wasserstein-2 distance has been employed in the temporal regularization of dynamic inverse problems. The so-called Benamou–Brenier formula states that it can be written as the square root of the performed physical work through the transport from the source to the sink. In my talk, I will instead focus on dynamic inverse problems regularized with Wasserstein-1 transport. The Wasserstein-1 distance can be interpreted as the optimal transport cost with respect to the Euclidean distance: it equals infπ R |x−y|dπ(x, y), where measure element dπ(x, y) indicates the (infinitesimal) amount of mass moving from location x to y. I will explain a novel dynamic inverse problem on time-parameterized curves in the induced Wasserstein-1 (metric) space. It is a natural extension of static sparse optimization problems such as lasso or TV regularization. One essential difference to classical regularization with Wasserstein-2 transport is that it allows for discontinuous decision variables (realized as BV curves). Despite this weak regularity requirement and the non-differentiability of the cost function (x, y) 7→ |x − y|, it is possible to prove the existence of a sparse solution and its characterization. I will present this result. Further, I will detail an adaption of the fully-corrective generalized conditional gradient method to the problem and highlight a natural discretization approach. Finally, I will show some numerical examples. Joint work with: Marcello Carioni

This event is a collaborative initiative between Japan Advanced Institute of Science and Technology (JAIST) and Okinawa Institute of Science and Technology (OIST), aimed at advancing new research developments in Gendered Innovation through the integration of both institutes’ strengths in advanced science and technology. Gendered Innovation offers critical perspectives not only for promoting femtech but also for applications in drug discovery, medical technologies, and materials development. Incorporating viewpoints on gender and broader diversity from the earliest stages of basic research is key to enhancing the quality and value of science. It also serves as a foundation for sustainable research and development that extends through applied research and ultimately contributes to social impact. In particular, Gendered Innovation is gaining global attention as a framework aligned with Responsible Research and Innovation (RRI) and with the promotion of fairness in research practices. By bridging diverse fields such as quantum science, materials science, and AI—alongside OIST’s core strengths in neuroscience, biology, and environmental science—this event seeks to foster interdisciplinary collaboration through the fusion of advanced research domains. The event aspires to create a platform where researchers from both institutions can share knowledge, explore emerging challenges, and shape new possibilities for future-oriented, transdisciplinary research.

Join us for iGEM Okinawa ’s 2025 post-Jamboree event at OIST, where we’ll share our project results with farmers, supporters, and stakeholders and discuss future collaborations.
