Ten quick tips for effective dimensionality reduction
Fig 9
Stability in the DR output coordinates for each data point. Projections of bootstrap samples for two 10D simulated datasets with rank 2 (a) and rank 5 (b) onto the first two PCs aligned using a Procrustes transformation. Smaller, circular markers correspond to each bootstrap trial, and larger, diamond markers are coordinates of the full dataset. DR, dimensionality reduction; PC, principal component.
