Enhancing Both Efficiency and Representational Capability of Isomap by Extensive Landmark Selection

Figure 9

2D embeddings of the sphere manifold data calculated by LLE, Laplacian eigenmap, Isomap, L-Isomap, and EL-Isomap, respectively. The squared points shown in the top left figure are the adopted landmarks by L-Isomap and EL-Isomap.
