I imagine he is suggesting to have an iterator that yields results while it's running, instead of only getting the result at the end of the run. On Sun, 19 Mar 2017 at 11:46 Joel Nothman wrote: > Not sure what you mean. Have you used cv_results_ > > On 18 March 2017 at 08:46, Carlton Banks wrot

Best bet for that at the moment is write a wrapper or mixin for your base estimator. On 19 March 2017 at 21:49, federico vaggi wrote: > I imagine he is suggesting to have an iterator that yields results while > it's running, instead of only getting the result at the end of the run. > > On Sun, 1

Thank you for your quick kind response. You got what I exactly want to know. Now I can expect my pre-processing methods are to be done. And also I have got clear now from this sklearn can help you with the AdaBoostClassifier, ranking of the features, and the evaluation of the pipeline. On Sun, Ma

[scikit-learn] recommended feature selection method to train an MLPRegressor

Which of the following methods would you recommend to select good features (<=50) from a set of 534 features in order to train a MLPregressor? Please take into account that the datasets I use for training are small. http://scikit-learn.org/stable/modules/feature_selection.html And please don't te

Hm, that’s tricky. I think the other methods listed on http://scikit-learn.org/stable/modules/feature_selection.html could help regarding a computationally cheap solution, but the problem would be that they probably wouldn’t work that well for an MLP due to the linear assumption. And an exhaust
