The context-specificity of virulence evolution revealed through evolutionary invasion analysis

no code implementations7 Nov 2023 Sudam Surasinghe, Ketty Kabengele, Paul E. Turner, C. Brandon Ogbunugafor

In this study, we invoke evolutionary invasion analysis -- a method used to identify the evolution of uninvadable strategies in dynamical systems -- to examine how the virulence-transmission dichotomy can evolve in models of virus infections defined by different natural histories.

Analysis of tidal flows through the Strait of Gibraltar using Dynamic Mode Decomposition

no code implementations2 Nov 2023 Sathsara Dias, Sudam Surasinghe, Kanaththa Priyankara, Marko Budišić, Larry Pratt, José C. Sanchez-Garrido, Erik M. Bollt

The Strait of Gibraltar is a region characterized by intricate oceanic sub-mesoscale features, influenced by topography, tidal forces, instabilities, and nonlinear hydraulic processes, all governed by the nonlinear equations of fluid motion.

Learning Transfer Operators by Kernel Density Estimation

1 code implementation1 Aug 2022 Sudam Surasinghe, Jeremie Fish, Erik M. Bollt

These findings provide valuable insights for researchers and practitioners working on estimating the Frobenius-Perron operator and highlight the potential of density estimation techniques in this area of study.

Randomized Projection Learning Method forDynamic Mode Decomposition

no code implementations22 Sep 2021 Sudam Surasinghe, Erik M. Bollt

In the spirit of Johnson-Lindenstrauss Lemma, we will use random projection to estimate the DMD modes in reduced dimensional space.

On Geometry of Information Flow for Causal Inference

no code implementations6 Feb 2020 Sudam Surasinghe, Erik M. Bollt

Our main contribution will be to develop analysis tools that will allow a geometric interpretation of information flow as a causal inference indicated by positive transfer entropy.
