Evolution of linear matter perturbations with error-bounded bundle physics-informed neural networks
Luca Gomez Bachar, Augusto T. Chantada, Susana J. Landau +2
We consider the evolution of linear matter perturbations in the context of the standard cosmological model (CDM) and a phenomenological modified gravity model. We use the physi…

Exact and approximate error bounds for physics-informed neural networks
Augusto T. Chantada, Pavlos Protopapas, Luca Gomez Bachar +2
The use of neural networks to solve differential equations, as an alternative to traditional numerical solvers, has increased recently. However, error bounds for the obtained solut…
