[mlpack] About implement tree types

[cuphrody]

Hi, Ryan


Thank you for response and telling me such important information and I'll looking for myself which kind of tree type to implement.
By the way, I've donwload mlpack1.0.8  but I didn't find the file "example_tree.hpp" in all the folders.I think you are meaning 
http://www.mlpack.org/trac/browser/trunk/src/mlpack/core/tree/example_tree.hpp this file and I've already seen. Thank you for telling 
that. I hope there will be a list about the algorithms or sturctures that somebody are working on on the website. :)

Hi there,

Many of the Summer of Code applicants have proposed to implement the R
tree, so it's safe to assume that somebody is already going to do that.
If you are interested in implementing tree types, maybe another thing to
try might be the quadtree or the octree (or an analog of that for
arbitrary dimensions, because the quadtree is tailored to 2-dimensional
data and the octree is tailored to 3-dimensional data).  I did not see
that tree type proposed in any of the Summer of Code applications, so
you could look into that.

I have been writing a tutorial on how trees work in mlpack, but I have
not had time to finish it yet.  For now you could look into the example
tree, in src/mlpack/core/tree/example_tree.hpp, to see the API that you
will need to implement.

Thanks,

Ryan
