Figure 2
Kernel density estimate (KDE) of the 1D example and the reconstructed data with 25 points using a Gaussian kernel. Results from various stages of optimization are shown as stems on the x axis which are sampled data ([\tilde{N} = 25]) from various stages of optimization. Initially from only integer approximation [\|\, f-\tilde{f}\| _{{1}} = 0.29] shown in green, after kernel optimization [\|\, f-\tilde{f}\| _{{1}} = 0.17] in blue and finally after subdivision optimization [\|\, f-\tilde{f}\| _{{1}} = 0.12] in red.
