Abstract:
In this work we further extend the action specific to the general relativity by including specific contractions of the Riemann tensor, discussing the emergence of the accelerated expansion in a two field model. The physical aspects of our solution are investigated by considering a machine learning approach, obtaining various dynamical properties which can explain the evolution of the universe at large scale.
