On Complexity of Stability Analysis in Higher-order Ecological Networks through Tensor Decompositions

no code implementations4 Jan 2024 Anqi Dong, Can Chen

Complex ecological networks are often characterized by intricate interactions that extend beyond pairwise relationships.

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.

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.

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.
