摘要:

规范化流(NF)正在成为一类强大的生成模型,因为它们不仅允许有效的采样,而且还通过构造提供密度估计。它们在高能物理中有着巨大的应用潜力,因为在高能物理中,复杂的高维数据和概率分布是日常生活的一部分。然而,为了充分利用NF的潜力,随着数据维度的增加,探索其鲁棒性至关重要。因此,在这篇文章中,我们讨论了市场上最流行的一些类型的NF的性能,在一些玩具数据集与越来越多的维度。

英文摘要:

Normalizing Flows (NFs) are emerging as a powerful class of generative models, as they not only allow for efficient sampling, but also deliver, by construction, density estimation. They are of great potential usage in High Energy Physics (HEP), where complex high dimensional data and probability distributions are everyday's meal. However, in order to fully leverage the potential of NFs it is crucial to explore their robustness as data dimensionality increases. Thus, in this contribution, we discuss the performances of some of the most popular types of NFs on the market, on some toy data sets with increasing number of dimensions.
