[Scikit-learn-general] Bootstrap aggregating

2013-06-21 Thread Maheshakya Wijewardena
Hi all, I would like to know whether we have bootstrap aggregating functionality in scikit-learn library. If so, How do I use that? (If it doesn't exist I would like to implement that explicitly to cohere with the learning algorithms we have in scikit-learn) Thank you

I'm doing a brownfield development for a university project and I'm so interested in this field. If I start implementing that kind ensemble method, will it suit in the scope of this scikit-learn project. Will it be useful for the users?( I've felt the need of that personally. It has improved the

So that means that bagging can only be applied to trees. How about implementing a general module so that it can be applied on more learning algorithms. On Fri, Jun 21, 2013 at 4:17 PM, Olivier Grisel olivier.gri...@ensta.orgwrote: 2013/6/21 Gilles Louppe g.lou...@gmail.com: Hi, Such

Thank you. I'll have look at the forest implementation and check what can be done and inform you. I'd like to have a look at Gilles s code. If it's convenient, can you tell how you tried to implement that? best Maheshakya On Fri, Jun 21, 2013 at 6:55 PM, Andreas Mueller
