Absence of spurious solutions far from ground truth: A low-rank analysis with high-order losses
Matrix sensing problems exhibit pervasive non-convexity, plaguing optimization with a proliferation of suboptimal spurious solutions. Avoiding convergence to these critical points poses a major challenge. This work provides new theoretical insights that help demystify the intricacies of the non-convex landscape. In this work, we prove that under certain conditions, critical points sufficiently distant from the ground truth matrix exhibit favorable geometry by being strict saddle points rather t…

Invariant Physics-Informed Neural Networks for Ordinary Differential Equations
Physics-informed neural networks have emerged as a prominent new method for solving differential equations. While conceptually straightforward, they often suffer training difficulties that lead to relatively large discretization errors or the failure to obtain correct solutions. In this paper we introduce invariant physics-informed neural networks for ordinary differential equations that admit a finite-dimensional group of Lie point symmetries. Using the method of equivariant moving frames, a d…

Distributions and Collision Rates of ALP Stars in the Milky Way
We apply current analytical knowledge on the characteristic mass and linear evolution of miniclusters down to redshift $z=0$ to the hypothetical minicluster distribution of the Milky Way. Using the mass-radius relation and a core-halo relation for stable soliton solutions composed of axion-like particles (ALPs), we connect the galactic minicluster mass distribution to that of their ALP star cores. We consider different temperature evolutions of the ALP field with masses in the range $10^{-12}\,…

Physics-constrained Active Learning for Soil Moisture Estimation and Optimal Sensor Placement
Soil moisture is a crucial hydrological state variable that has significant importance to the global environment and agriculture. Precise monitoring of soil moisture in crop fields is critical to reducing agricultural drought and improving crop yield. In-situ soil moisture sensors, which are buried at pre-determined depths and distributed across the field, are promising solutions for monitoring soil moisture. However, high-density sensor deployment is neither economically feasible nor practical…

Na, super. Ich hatte neulich mal jemandem, der „der Junge“ in der Klausur als Dativ eingeordnet hatte, geraten, doch noch mal drüber nachzudenken, ob er/sie wirklich im Master Linguistik studieren will. Vielleicht doch noch mal Grundkurs im BA, denn eigentlich ist das ja dritte Klasse in der Schule.
Nun hat @… einen Fehler in der Grammatiktheorie gefunden. Da steht „des“ für einen Artikel im Nominativ. Und zwar seit 2010. In der deutschen Ausgabe. Dann Übersetzung. Proofreading. Hunderte Lehrveranstaltungen. Es hat nie jemand gesehen.
Also: Glaubt niemandem! Schon gar nicht Euch selber. Und wenn Ihr was nicht versteht, dann so lange nachfragen bzw. nachdenken, bis Ihr es versteht.
Viel Spaß!
PS: In den Folien kommt diese Passage nicht vor. Sonst hätte ich es wohl gemerkt. Das Buch selbst gucke ich nur selten an.

Existence of Weak Solutions to a Cahn-Hilliard-Biot System
We prove existence of weak solutions to a diffuse interface model describing the flow of a fluid through a deformable porous medium consisting of two phases. The system non-linearly couples Biot's equations for poroelasticity, including phase-field dependent material properties, with the Cahn-Hilliard equation to model the evolution of the solid, and is further augmented by a visco-elastic regularization consistent with secondary consolidation. To obtain this result, we approximate the problem …
