Figure 13

Each box shows a pair of NMF basis vectors \(w_{k}\) (left) and \(h_{k}\) (right). From top to bottom: \(k=7,8,9\). See the caption of Fig. 11 for explanation. Note that for the box \(k=7\), the basis \(h_{k=7}\) (right figure) has its vector components of destination widely distributed over the Shiga prefecture and its neighbor in Kyoto, which is located to the left (west) of Shiga. So, in this exceptional case, the figure does not include a circle corresponding to any peak of vector components
