[scikit-learn] Sampling capabilities and uncertainty quantification

Hi, >From the doc, I have not found a sampling class. To train a gaussian process for example, It is preferable to use sampling techniques (low discrepancy sequences, uniform designs, etc.). Do you plan to do such a thing? Also, I was wondering if you were planning to add variance analysis (Sobo

[scikit-learn] Update or downgrade PCA

Hi everyone, I have some code that allows to upgrade (or downgrade) a PCA with a new sample. The update part is handy when you are doing live observations for instance and you want a quick way to update your PCA without having to recompute the whole thing from scratch. Are you interested in this?

Re: [scikit-learn] Update or downgrade PCA

I have no idea about the comparison with sklearn.decomposition.IncrementalPCA. Was not aware of this but from the code it seems to be a different approach. I will try to come with some numbers. Pamphile ___ scikit-learn mailing list scikit-learn@python.o

[scikit-learn] Sensitivity analysis PR proposal

Hi, Is there a wish to have sensitivity analysis? Currently we can measure the quality of a regressor’s output with a metric, but there is nothing to on the parameter side. It would be handy to have sensitivity measures of the input parameters on the output. Namely: Sobol’ indices (most used).
