Koopman Q-learning: Offline Reinforcement Learning via Symmetries of Dynamics
Matthias Weissenbacher, Samarth Sinha, Animesh Garg +1
Offline reinforcement learning leverages large datasets to train policies without interactions with the environment. The learned policies may then be deployed in real-world setting…
A Quadratic Actor Network for Model-Free Reinforcement Learning
Matthias Weissenbacher, Yoshinobu Kawahara
In this work we discuss the incorporation of quadratic neurons into policy networks in the context of model-free actor-critic reinforcement learning. Quadratic neurons admit an exp…

Matthias Weissenbacher
In this work we study type IIB Calabi-Yau orientifold compactifications in the presence of space-time filling D7-branes and O7-planes. In particular, we conclude that -co…
Temporally Folded Convolutional Neural Networks for Sequence Forecasting
Matthias Weissenbacher
In this work we propose a novel approach to utilize convolutional neural networks for time series forecasting. The time direction of the sequential data with spatial dimensions $D=…
-Corrections and de Sitter Vacua - a Mirage?
Matthias Weissenbacher
In this work we analyze the role of -corrections to type IIB orientifold compactifications in Kähler moduli stabilization and inflation. In particular, we propose a model indep…

In this work we analyze F-theory and Type IIB orientifold compactifications to study -corrections to the four-dimensional, effective actions. In particular, w…
One-modulus Calabi-Yau fourfold reductions with higher-derivative terms
Thomas W. Grimm, Kilian Mayer, Matthias Weissenbacher
In this note we consider M-theory compactified on a warped Calabi-Yau fourfold including the eight-derivative terms in the eleven-dimensional action known in the literature. We dim…
Higher derivatives in Type II and M-theory on Calabi-Yau threefolds
Thomas W. Grimm, Kilian Mayer, Matthias Weissenbacher
The four- and five-dimensional effective actions of Calabi-Yau threefold compactifications are derived with a focus on terms involving up to four space-time derivatives. The starti…
The Euler characteristic correction to the Kaehler potential - revisited
Federico Bonetti, Matthias Weissenbacher
We confirm the leading correction to the 4d, Kähler potential of type IIB orientifold compactifications, proportional to the Euler characteristic of the Cal…

Matthias Weissenbacher
We perform a Kaluza-Klein reduction of IIB supergravity including purely gravitational -corrections on a Calabi-Yau threefold, and perform the orientifold projection accounti…

Thomas W. Grimm, Tom G. Pugh, Matthias Weissenbacher
We study the three-dimensional effective action obtained by reducing eleven-dimensional supergravity with higher-derivative terms on a background solution including a warp-factor,…
The effective action of warped M-theory reductions with higher derivative terms - Part I
Thomas W. Grimm, Tom G. Pugh, Matthias Weissenbacher
M-theory accessed via eleven-dimensional supergravity admits globally consistent warped solutions with eight-dimensional compact spaces if background fluxes and higher derivative t…

Thomas W. Grimm, Tom G. Pugh, Matthias Weissenbacher
We study solutions to the eleven-dimensional supergravity action, including terms quartic and cubic in the Riemann curvature, that admit an eight-dimensional compact space. The int…

Thomas W. Grimm, Jan Keitel, Raffaele Savelli +1
We perform a Kaluza-Klein reduction of eleven-dimensional supergravity on a Calabi-Yau fourfold including terms quartic and cubic in the Riemann curvature and determine the induced…
