Integer coding will indeed make the DT assume an arbitrary ordering while one-hot encoding does not force the tree model to make that assumption. However in practice when the depth of the trees is not too limited (or if you use a large enough ensemble of trees), the model will have enough flexibil

Re: [scikit-learn] decision trees

For large enough models (e.g. random forests or gradient boosted trees ensembles) I would definitely recommend arbitrary integer coding for the categorical variables. Try both, use cross-validation and see for yourself. -- Olivier ___ scikit-learn mail

Re: [scikit-learn] Logistic regression with elastic net regularization

>From a generalization point of view (test accuracy), the optimal sparsity support should not matter much though, but it can be helpful to find a the optimally sparsest solution for either computational constraints (smaller models with a lower prediction latency) and interpretation of the weights (

Re: [scikit-learn] Logistic regression with elastic net regularization

Note that SGD is not very good at optimizing finely with a non-smooth penalty (e.g. l1 or elasticnet). The future SAGA solver is going to be much better at finding the optimal sparsity support (although this support is not guaranteed to be stable across re-sampling of the training set if the traini

Re: [scikit-learn] GSOC call for mentors

Personally I don't feel like mentoring this year. I would really like to focus my scikit-learn time on finishing the joblib process refactoring with Thomas Moreau and the binning / thread-based parallelization of boosted trees with Guillaume and Raghav. -- Olivier

Re: [scikit-learn] Modelling event rates

I don't think we have any model dedicated to this, but it's possible that expressive non-parametricmodels such as RF and GBRT or richly parameterized models such as MLP with a regression loss can do a good enough job at giving you a point estimate. -- Olivier _

Re: [scikit-learn] Need help to start contributing

It's ok to work on a bug if the original contributor has not replied to the reviewers comments in a while (e.g. a couple of weeks). -- Olivier ___ scikit-learn mailing list scikit-learn@python.org https://mail.python.org/mailman/listinfo/scikit-learn
