Data-driven optimal control under safety constraints using sparse Koopman approximation
Hongzhe Yu, Joseph Moyalan, Umesh Vaidya +1
In this work we approach the dual optimal reach-safe control problem using sparse approximations of Koopman operator. Matrix approximation of Koopman operator needs to solve a leas…
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…
DiffCollage: Parallel Generation of Large Content with Diffusion Models
Qinsheng Zhang, Jiaming Song, Xun Huang +2
We present DiffCollage, a compositional diffusion model that can generate large content by leveraging diffusion models trained on generating pieces of the large content. Our approa…
Signed Graph Neural Networks: A Frequency Perspective
Rahul Singh, Yongxin Chen
Graph convolutional networks (GCNs) and its variants are designed for unsigned graphs containing only positive links. Many existing GCNs have been derived from the spectral domain…
Inertialess Gyrating Engines
Jordi Ventura Siches, Olga Movilla Miangolarra, Amirhossein Taghvaei +2
A typical model for a gyrating engine consists of an inertial wheel powered by an energy source that generates an angle-dependent torque. Examples of such engines include a pendulu…
Stochastic thermodynamic engines under time-varying temperature profile
Rui Fu, Olga Movilla Miangolarra, Amirhossein Taghvaei +2
In the present paper, we study the power output and efficiency of overdamped stochastic thermodynamic engines that are in contact with a heat bath having a temperature that varies…
