Indeed, the digits are vectors in a 8*8 = 64 dimensional space. We want to project them in 2D for visualization. tSNE is often a good solution, as it groups and separates data points based on their ... WebThe following statements reduce the dataset x to 5 dimensions, regardless of the number of dimensions it originally contains: pca = PCA(n_components=5) x = pca.fit_transform(x) You can also invert a PCA transform to restore the original number of dimensions: x = pca.inverse_transform(x)
