Can you do a PCA(3) and plot projection of axis 0 vs axis 1, then axis 0 vs axis 1 and axis 1 vs axis 2? It seems that class "r+" is almost linearly separable using the first 2 components while the 3 others are not at all. -- Olivier http://twitter.com/ogrisel - http://github.com/ogrisel ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
