Splet29. avg. 2024 · Laurens illustrates the PCA and t-SNE approach pretty well using the Swiss Roll dataset in Figure 1 [1]. You can see that due to the non-linearity of this toy dataset (manifold) and preserving large distances that PCA would incorrectly preserve the structure of the data. Figure 1 — Swiss Roll Dataset. SpletSwiss Roll: data is essentially a rectangle, but has been “rolled up” like a swiss roll in three dimensional space. Ideally a dimension reduction technique should be able to “unroll” it. The data has been coloured according to one dimension of the rectangle, so should form a rectangle of smooth color variation. fun crafts to make out of paperSpletOn the left, we show the diffusion map embedding given by the first two diffusion coordinates.
