[Scikit-learn-general] sklearn.cross_decomposition.PLSRegression: would like to fix the scaling issue

2015-12-17 Thread Ola Pawluczyk
Hi Andy and all, I've had more time to play around with this problem, and I would like to take a stab at fixing the scaling issues I found and reported in https://github.com/scikit-learn/scikit-learn/issues/6002 Is there someone who has ownership of the cross_decomposition module? I am very new

[Scikit-learn-general] sklearn.cross_decomposition.PLSRegression: how to re-scale my prediction?

2015-12-02 Thread Ola Pawluczyk
Hello all, I'm doing a PLS regression on spectral data [x.train] with respect to concentrations of a few substances [y.train], and find that centering/scaling my data gives me good stats. However, my y_pred_train is always scaled, and I cannot figure out how to get it back to the unscaled space.
