Schrödinger's control and estimation paradigm with spatio-temporal distributions on graphs

no code implementations9 Dec 2023 Asmaa Eldesoukey, Tryphon T. Georgiou

The problem of reconciling a prior probability law with data was introduced by E. Schr\"odinger in 1931/32.

Data Assimilation for Sign-indefinite Priors: A generalization of Sinkhorn's algorithm

no code implementations22 Aug 2023 Anqi Dong, Tryphon T. Georgiou, Allen Tannenbaum

The resulting algorithm generalizes the Sinkhorn algorithm in that it amounts to iterative scaling of the entries of the array along different coordinate directions.

Promotion/Inhibition Effects in Networks: A Model with Negative Probabilities

no code implementations15 Jul 2023 Anqi Dong, Tryphon T. Georgiou, Allen Tannenbaum

Herein we address the inverse problem to determine network edge-weights based on a sign-indefinite adjacency and expression levels at the nodes.

A matching principle for power transfer in Stochastic Thermodynamics

no code implementations17 Mar 2023 Olga Movilla Miangolarra, Amirhossein Taghvaei, Tryphon T. Georgiou

Gradients in temperature and particle concentration fuel many processes in the physical and biological world.

Monge-Kantorovich Optimal Transport Through Constrictions and Flow-rate Constraints

1 code implementation30 Dec 2022 Anqi Dong, Arthur Stephanovitch, Tryphon T. Georgiou

We quantify flow-rate constraints via a bound on a sought probability density of the times that mass-elements cross toll stations and cast the transportation scheduling in a Kantorovich-type of formalism.

Scheduling

Optimal transport through a toll

no code implementations6 Aug 2022 Arthur Stephanovitch, Anqi Dong, Tryphon T. Georgiou

We provide a precise formulation which, in addition, is amenable to generalization in higher dimensions.

Geometry of finite-time thermodynamic cycles with anisotropic thermal fluctuations

no code implementations23 Mar 2022 Olga Movilla Miangolarra, Amirhossein Taghvaei, Yongxin Chen, Tryphon T. Georgiou

In contrast to the classical concept of a Carnot engine that alternates contact between heat baths of different temperatures, naturally occurring processes usually harvest energy from anisotropy, being exposed simultaneously to chemical and thermal fluctuations of different intensities.

Stochastic dynamical modeling of turbulent flows

no code implementations26 Aug 2019 Armin Zare, Tryphon T. Georgiou, Mihailo R. Jovanović

Drawing on this abundance of data, dynamical models can be constructed to reproduce structural and statistical features of turbulent flows, opening the way to the design of effective model-based flow control strategies.

Probabilistic Kernel Support Vector Machines

no code implementations14 Apr 2019 Yongxin Chen, Tryphon T. Georgiou, Allen R. Tannenbaum

We propose a probabilistic enhancement of standard kernel Support Vector Machines for binary classification, in order to address the case when, along with given data sets, a description of uncertainty (e. g., error bounds) may be available on each datum.

Binary Classification

Proximal algorithms for large-scale statistical modeling and sensor/actuator selection

no code implementations4 Jul 2018 Armin Zare, Hesameddin Mohammadi, Neil K. Dhingra, Tryphon T. Georgiou, Mihailo R. Jovanović

Several problems in modeling and control of stochastically-driven dynamical systems can be cast as regularized semi-definite programs.
