Mechanical response of a NCB under external loading. Behavior of the projection error \(E_{it}^{\textrm{proj}}\) (34) for parameters selected by Algorithm 7 based on coarse (mesh 1) and fine data (mesh 2); comparison with random sampling. a Performance on \(\mathcal {P}_{\textrm{test}}\) (\(5 \times 5\)). b Performance on \(\mathcal {P}_{\textrm{train}}\) (\(7 \times 7\)). c Behavior of the basis size \(n_{it}\)
