KNN classification for cell-cycle data. The classification accuracy obtained using the combined representation as a function of dimensionality. The CCA-based combination (solid line) is clearly superior to PCA-based approach (dashed line) for a wide range of dimensionalities and obtains higher maximal accuracy. As a baseline, the classification accuracy obtained by the concatenation of all original data sets (dotted line) is also included.
