Table 5. Algorithm Comparison Summary: ULI vs. SDM.

Pros/Cons Summary
Sparse Diffusion Maps Unweighted Landmark Isomap
Con: Only accurately reconstructs cubes Pro: Can accurately reconstruct non-cubes
Con: Biased towards exterior points Pro: Not biased towards exterior points
Pro: Is robust to problems that have high similarity between some far-away points. Con: Is generally not robust to problems that have high similarity between some far-away points.
