Fig. 1From: Visual analytics for concept exploration in subspaces of patient groupsEffects in high-dimensional data: some objects are only similar in a subset of dimensions (=subspace), e.g., \(rec_1,\,rec_2,\,rec_3\) in the first three and \(rec_3,\,rec_{n-1},\,rec_n\) in the last three dimensions. Similar values in specific dimensions are encoded by the same color. (Color figure online)Back to article page
