Figure 3From: Spectral embedding finds meaningful (relevant) structure in image and microarray dataImages ordered by the primary eigenfunction for PCA-correlation and the spectral method from Lafon [3,4]. (a) The ordering is not correctly preserved with PCA-correlation (in this series, moving from left to right and top to bottom). (b) The order is correctly preserved with the spectral method from Lafon [3,4] (in this series, moving from left to right and top to bottom).Back to article page
