Multivariate data sets suffer from the problemofrepresentation, since a dimensionality above 3 is beyond the capability of plotting programs.
多元数据集遭受着表征的问题，因为三维以上超越了绘图程序的能力。

Emphasizes the problemofrepresentation, exploring the issue of how 3-D objects should be encoded so as to efficiently recognize them from 2-D images.
着重于物体的呈现方式，检视3度空间物体如何有效率地对应边编码成可供辨识的2度空间影像。

Exceptions, of course, being configuration issues that appear in the problem domain, such as currency representation, though even that could be done automatically by detecting the current locale.
