Consider a continuous kernel 2 e ? 5 ? in graph spectral domain. Corresponding to this kernel, plot the graph signal with its structure being the graph shown in Figure 9.1. For the obtained graph signal, what is the total variation? Repeat the same for a kernel 2 e 2 ? . What is the total variation for this graph signal? Compare it with the previous result.
