Fig. 5From: Dimension independent data sets approximation and applications to classificationLevel lines of 20%, 50%, and 80%, increasingly dark, of the signal’s maximal value for regularizations parameter \(\alpha =.1,1,2.\), from left to right. The number of randomly sampled points, also depicted with the associated value color-coded (with blue representing the value 1, while magenta the value 0), is 1024 as in the denser regular grids of previous examplesBack to article page
