On Quantitative Comparison of Chemical Reaction Network Models [PDF]
Electronic Proceedings in Theoretical Computer Science, 2019 Chemical reaction networks (CRNs) provide a convenient language for modelling a broad variety of biological systems. These models are commonly studied with respect to the time series they generate in deterministic or stochastic simulations. Their dynamic

Autonomous learning of generative models with chemical reaction network ensembles
Journal of the Royal Society InterfaceCan a micron-sized sack of interacting molecules autonomously learn an internal model of a complex and fluctuating environment? We draw insights from control theory, machine learning theory, chemical reaction network theory and statistical physics to develop a general architecture whereby a broad class of chemical systems can autonomously learn complex

Inferring structure and parameters of stochastic reaction networks with logistic regression. [PDF]
PLoS ONEIdentifying network structure and estimating reaction parameters remain central challenges in modeling chemical reaction networks. In this work, we develop likelihood-based methods that use multinomial logistic regression to infer both stoichiometries ...

Diffusive network connected chemical reaction networks
Systems Science & Control EngineeringA novel type of networked Chemical Reaction Network (CRN) model is proposed in this paper where the CRN subsystem nodes are connected in a bi-directional state-difference-driven way, forming a diffusive network. The diffusive connecting elements can also

Model discrimination of chemical reaction networks by linearization [PDF]
Proceedings of the 2010 American Control Conference, 2010 Systems biologists are often faced with competing models for a given experimental system. Performing experiments can be time-consuming and expensive. Therefore, a method for designing experiments that, with high probability, discriminate between competing models is desired.

The GRETOBAPE Gas-phase Reaction Network: The Importance of Being Exothermic
The Astrophysical Journal Supplement Series, 2023 The gas-phase reaction networks are the backbone of astrochemical models. However, due to their complexity and nonlinear impact on the astrochemical modeling, they can be the first source of error in the simulations if incorrect reactions are present ...
