论文摘要
本文介绍了使用低维线性投影和切片检查高维数据的新用户控件。用户可以交互性地更改给定变量对低维投影的贡献，这对于探索结构对特定变量的敏感性很有用。用户还可以交互方式移动切片的中心，例如探索本地子空间中结构的变化。提供了Mathematica软件包以及示例笔记本，其中包含功能，使用户可以尝试这些新的手动控件，专门用于探索由分类模型产生的区域和边界。 Mathematica的优点是其线性代数功能和交互式光标位置控件。 R Package Tourr也提供了一些有限的实施。
This paper describes new user controls for examining high-dimensional data using low-dimensional linear projections and slices. A user can interactively change the contribution of a given variable to a low-dimensional projection, which is useful for exploring the sensitivity of structure to particular variables. The user can also interactively shift the center of a slice, for example, to explore how structure changes in local subspaces. The Mathematica package as well as example notebooks are provided, which contain functions enabling the user to experiment with these new manual controls, with one specifically for exploring regions and boundaries produced by classification models. The advantage of Mathematica is its linear algebra capabilities, and interactive cursor location controls. Some limited implementation has also been made available in the R package tourr.
