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

Figure 10

2D embeddings of the pig image data calculated by LLE, Laplacian eigenmap, Isomap, L-Isomap, and EL-Isomap, respectively. The images shown on top of each embeddings are images corresponding to the circled points with increasing order of their first coordinates. The fuscous points shown in the embeddings got by L-Isomap and EL-Isomap are the adopted landmarks by the methods.
