Re: [Scikit-learn-general] Bootstrap aggregating
Ok, I got it. I'll look at the code and see what can be done. Thank you. On Fri, Jun 21, 2013 at 7:17 PM, Andreas Mueller wrote: > On 06/21/2013 03:37 PM, Maheshakya Wijewardena wrote: > > Thank you.

Re: [Scikit-learn-general] Bootstrap aggregating
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 wrote: > On 06/21/2013 12:56 PM, Maheshakya Wijewardena wrote: > > So that means that bagging can only be applied to trees.

You can probably reuse some code. I think Gilles started that long ago but didn't have the time to finish.

Re: [Scikit-learn-general] Bootstrap aggregating
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.

Re: [Scikit-learn-general] Bootstrap aggregating
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 results when used with other learning algorithms for certain cases) What help can I get from the community?

Hi, Such ensembles are not implemented at the moment.

[Scikit-learn-general] Bootstrap aggregating
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 -- This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev___ Scikit-learn-general mailing list Scikit-learn-general@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/scikit-learn-general
