Fig. 7From: Dimension independent data sets approximation and applications to classificationThe 50% of maximum level lines for the signals \(u_{\mathbb {D}_C}\) and \(u_{\mathbb {D}_S}\) of the data sets based on the two data classes \(C_k\) and \(S_k\) for \(k=1,2\). The first two rows correspond to \(k=1\) and the second two to \(k=2\). Withing each row, from left to right, the regularization parameter is \(\alpha =.1,1,2\)Back to article page
