摘要

我们介绍了一个研究小尺度原始扰动及其宇宙学影响的新框架。该框架利用深度强化学习来生成与当前观测约束相一致的标量功率谱剖面。研究表明,该框架可以预测原始黑洞的丰度和二次诱导引力波的产生。我们证明了所考虑的设置能够产生超越传统基于模型方法的预测结果。

Generic predictions for primordial perturbations and their implications

We introduce a novel framework for studying small-scale primordial perturbations and their cosmological implications. The framework uses a deep reinforcement learning to generate scalar power spectrum profiles that are consistent with current observational constraints. The framework is shown to predict the abundance of primordial black holes and the production of secondary induced gravitational waves. We demonstrate that the set up under consideration is capable of generating predictions that are beyond the traditional model-based approaches.
