The Use of Faces to Represent Points in K-Dimensional Space Graphically

Abstract

A novel method of representing multivariate data is presented. Each point in k-dimensional space, k ≤ 18, is represented by a cartoon of a face whose features, such as length of nose and curvature of mouth, correspond to components of the point. Thus every multivariate observation is visualized as a computer-drawn face. This presentation makes it easy for the human mind to grasp many of the essential regularities and irregularities present in the data. Other graphical representations are described briefly.
