A physics-informed neural network method for the approximation of slow invariant manifolds for the general class of stiff systems of ODEs

no code implementations18 Mar 2024 Dimitrios G. Patsatzis, Lucia Russo, Constantinos Siettos

We present a physics-informed neural network (PINN) approach for the discovery of slow invariant manifolds (SIMs), for the most general class of fast/slow dynamical systems of ODEs.

Slow Invariant Manifolds of Singularly Perturbed Systems via Physics-Informed Machine Learning

no code implementations14 Sep 2023 Dimitrios G. Patsatzis, Gianluca Fabiani, Lucia Russo, Constantinos Siettos

A comparison of the computational costs between symbolic, automatic and numerical approximation of the required derivatives in the learning process is also provided.

Data-driven Control of Agent-based Models: an Equation/Variable-free Machine Learning Approach

no code implementations12 Jul 2022 Dimitrios G. Patsatzis, Lucia Russo, Ioannis G. Kevrekidis, Constantinos Siettos

We present an Equation/Variable free machine learning (EVFML) framework for the control of the collective dynamics of complex/multiscale systems modelled via microscopic/agent-based simulators.
