摘要

我们研究了使用一种新的强化学习技术来适应早期和后期紧张的可能性。通过应用这项技术,我们的目标是优化哈勃参数从重组到现在的演变,同时解决这两个紧张关系。为了最大化拟合优度,我们的学习技术实现了甚至超过ΛCDM模型的拟合。我们的结果表明,在一个完全独立于模型的方式削弱早期和晚期的紧张趋势。

Reconciling early and late time tensions with Reinforcement Learning
We study the possibility of accommodating both early and late-time tensions using a novel reinforcement learning technique. By applying this technique, we aim to optimize the evolution of the Hubble parameter from recombination to the present epoch, addressing both tensions simultaneously. To maximize the goodness of fit, our learning technique achieves a fit that surpasses even the ΛCDM model. Our results demonstrate a tendency to weaken both early and late time tensions in a completely model-independent manner.

期刊介绍: Journal of Cosmology and Astroparticle Physics (JCAP) encompasses theoretical, observational and experimental areas as well as computation and simulation. The journal covers the latest developments in the theory of all fundamental interactions and their cosmological implications (e.g. M-theory and cosmology, brane cosmology). JCAP''s coverage also includes topics such as formation, dynamics and clustering of galaxies, pre-galactic star formation, x-ray astronomy, radio astronomy, gravitational lensing, active galactic nuclei, intergalactic and interstellar matter.
