Im September habe ich einen kleinen Lehrauftrag für 3 Einheiten (a 45 Minuten) an einer Berliner Hochschule. "KI" blabla. Weiß jetzt, was dafür bezahlt wird.
45 EUR pro Einheit, für den ganzen 90-100 Minuten Vortrag Diskussion also 135 EUR. Talking about Wertschätzung und so.

Learning Binary Sampling Patterns for Single-Pixel Imaging using Bilevel Optimisation
Single-Pixel Imaging enables reconstructing objects using a single detector through sequential illuminations with structured light patterns. We propose a bilevel optimisation method for learning task-specific, binary illumination patterns, optimised for applications like single-pixel fluorescence microscopy. We address the non-differentiable nature of binary pattern optimisation using the Straight-Through Estimator and leveraging a Total Deep Variation regulariser in the bilevel formulation. We…

Unangenehme Theorie, die heute in einem Gespräch hoch kam:
SPD will jetzt auch AfD Verbot, aber CDU sperrt sich auf Bundesebene ("Blabla, politisch stellen"). So gibts kein AfD Verbot.
Dann finden sich ein paar CDU Abweichler (Günther in SH zum Beispiel), die über den Bundesrat dann einen Antrag möglich machen: So kann die Bundes-CDU dann so tun, als hätte man das nicht gewollt und ganze Kreisverbände der AfD in sich aufnehmen (weil man quasi einzige Zuflucht ist und di…

I had the pleasure of viewing the Blobulator, hearing the Blobulator, and touching the Blobulator. It was highly Blobulating. I am well Blobulated. The video does not do justice to its Blobulusciousness. I recommend Blobulation to anyone seeking greater Blobularity in their life.

Ridiculous I have to give a reason and a minimum 10 character explanation before I can delete my Proton account.
Wonder now where my 'blahblahblah' will end up.

Joint Inference of Trajectory and Obstacle in Mean-Field Games via Bilevel Optimization
Mean field game (MFG) is an expressive modeling framework for systems with a continuum of interacting agents. While many approaches exist for solving the forward MFG, few have studied its \textit{inverse} problem. In this work, we seek to recover optimal agent trajectories and the unseen spatial obstacle given partial observation on the former. To this end, we use a special type of generative models, normalizing flow, to represent the trajectories and propose a novel formulation of inverse MFG …

Tikhonov regularized exterior penalty methods for hierarchical variational inequalities
We consider nested variational inequalities con- sisting in a (upper-level) variational inequality whose feasible set is given by the solution set of another (lower-level) variational inequality. This class of hierarchical equilibrium contains a wealth of important applications, including purely hierarchical convex bilevel optimization problems and certain multi-follower games. Working within a real Hilbert space setting, we develop a double loop prox-penalization algorithm with strong conver- …
