An Information-State Based Approach to Linear Time Varying System Identification and Control

Kavli Affiliate: Ran Wang | First 5 Authors: Mohamed Naveed Gul Mohamed, Raman Goyal, Suman Chakravorty, Ran Wang, | Summary: This paper considers the problem of system identification for linear time varying systems. We propose a new system realization approach that uses an "information-state" as the state vector, where the "information-state" is composed of a […]

Self-regulating surfaces for efficient liquid collection

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Christian Machado, Yuehan Yao, Emma Feldman, Joanna Aizenberg, Kyoo-Chul Kenneth Park | Summary: To achieve efficient liquid collection, a surface must regulate incoming liquid accumulation with outgoing liquid transport. Often, this can be proposed to be achieved by functionalizing surfaces with non-wetting characteristics. Yet, there remain fundamental, […]

Electrostatic control of the proximity effect in the bulk of semiconductor-superconductor hybrids

Kavli Affiliate: L. P. Kouwenhoven | First 5 Authors: N. van Loo, G. P. Mazur, T. Dvir, G. Wang, R. C. Dekker | Summary: The proximity effect in semiconductor-superconductor nanowires is expected to generate an induced gap in the semiconductor. The magnitude of this induced gap, together with the semiconductor properties like the spin-orbit coupling […]

Spectral bounds for exit times on metric measure Dirichlet spaces and applications

Kavli Affiliate: Jing Wang | First 5 Authors: Phanuel Mariano, Jing Wang, , , | Summary: Assuming the heat kernel on a doubling Dirichlet metric measure space has a generalized sub-Gaussian bound, we prove an asymptotically sharp spectral upper bound on the survival probability of the associated diffusion process. As a consequence, we can show […]

FIXED: Frustratingly Easy Domain Generalization with Mixup

Kavli Affiliate: Xiang Zhang | First 5 Authors: Wang Lu, Jindong Wang, Han Yu, Lei Huang, Xiang Zhang | Summary: Domain generalization (DG) aims to learn a generalizable model from multiple training domains such that it can perform well on unseen target domains. A popular strategy is to augment training data to benefit generalization through […]
