Re: [Scikit-learn-general] Speeding up K-means clustering model with fast approximate neighbor search methods

Is that so? I'm sorry. I haven't checked the implementation of hierarchical clustering yet. What do you think about the approach I suggested for k-means clustering? On Fri, Apr 11, 2014 at 12:02 PM, Gael Varoquaux < gael.varoqu...@normalesup.org> wrote: > > I think we can improve hierarchical cl

I think we can improve hierarchical clustering and dbscan as well with approximate neighbor search. I will update you after I have investigated those implementations further. Thank you. On Thu, Apr 10, 2014 at 4:12 AM, Robert Layton wrote: > I think you are right. Updating k-means to be more ef

[Scikit-learn-general] Combine SVR kernels

2014-04-10 Thread João André
Hi! I have a question regarding support vectors regression. Is it possible to develope a kernel that combines the linear and the rbf kernel, that is, it uses both kernels and applies each one to a region where each kernel fits better the data? I thought of this because I was asked to fit this sim
