AI总结:

本研究比较了两种最先进的基于分数的生成模型在量能器快速模拟中的表现,发现点云比3D体素图像更自然且更紧凑。

摘要:

基于分数的生成模型是一类新型生成模型,已被证明能准确生成高维量能器数据集。生成模型的最新进展利用带有3D体素的图像来表示和建模复杂的量能器簇射。然而,点云可能是量能器簇射更自然的表示,特别是在高粒度量能器中。点云保留了原始模拟的所有信息,更自然地处理稀疏数据集,并且可以用更紧凑的模型和数据文件实现。在这项工作中,两个最先进的基于分数的模型在相同的量能器模拟集上进行训练并直接比较。

英文摘要:

Score based generative models are a new class of generative models that have been shown to accurately generate high dimensional calorimeter datasets. Recent advances in generative models have used images with 3D voxels to represent and model complex calorimeter showers. Point clouds, however, are likely a more natural representation of calorimeter showers, particularly in calorimeters with high granularity. Point clouds preserve all of the information of the original simulation, more naturally deal with sparse datasets, and can be implemented with more compact models and data files. In this work, two state-of-the-art score based models are trained on the same set of calorimeter simulation and directly compared.
