论文摘要
所有学科的科学家都越来越依赖机器学习算法来分析和分类数量和复杂性不断增加的数据集。尽管很容易提取趋势和离群值,但仍需要进行仔细和仔细检查以探索和解开详细的行为,并确定系统学和误报。因此,我们必须纳入新技术来促进科学分析和探索。天体物理数据本质上是多参数,其空间基因尺寸处于观测和仿真的核心。主流虚拟现实(VR)耳机的到来和增加的GPU功率以及视频游戏的多功能开发工具的可用性,使科学家能够部署此类技术来有效询问和与复杂的数据相互作用。在本文中,我们介绍了定制的交互式VR工具(称为Idavie Suite)的开发和结果,这些工具是由有关星系进化,宇宙大规模结构,星系 - 果胶相互作用以及附近星系中附近星系的气体/基因学的研究和驱动的。在诸如SKA和LSST之类的主要设施中引入的大数据的新时代,使过去的分析和改进方法高度受到限制,我们认为,将范式转移到利用视觉感知力量的新软件,技术和方法中,将在统计计量和新发现之间弥补差距中越来越重要的作用。我们发布了免费并向社区开放的IDAVIE软件系统的Beta版本。
Scientists across all disciplines increasingly rely on machine learning algorithms to analyse and sort datasets of ever increasing volume and complexity. Although trends and outliers are easily extracted, careful and close inspection will still be necessary to explore and disentangle detailed behavior, as well as identify systematics and false positives. We must therefore incorporate new technologies to facilitate scientific analysis and exploration. Astrophysical data is inherently multi-parameter, with the spatial-kinematic dimensions at the core of observations and simulations. The arrival of mainstream virtual-reality (VR) headsets and increased GPU power, as well as the availability of versatile development tools for video games, has enabled scientists to deploy such technology to effectively interrogate and interact with complex data. In this paper we present development and results from custom-built interactive VR tools, called the iDaVIE suite, that are informed and driven by research on galaxy evolution, cosmic large-scale structure, galaxy-galaxy interactions, and gas/kinematics of nearby galaxies in survey and targeted observations. In the new era of Big Data ushered in by major facilities such as the SKA and LSST that render past analysis and refinement methods highly constrained, we believe that a paradigm shift to new software, technology and methods that exploit the power of visual perception, will play an increasingly important role in bridging the gap between statistical metrics and new discovery. We have released a beta version of the iDaVIE software system that is free and open to the community.
