Dongryeol Lee 47ccf11658 Renamed pca_tree.h to subspace_stat.h. This file will be templatized for different ways of stitching up two different subspaces. 2008-04-19 22:12:09 +00:00
Dongryeol Lee a5e6e06812 Minor change to the dualtree_kde.h to use InitCopy instead of Copy, a deprecated function. 2008-04-19 21:47:06 +00:00
Dongryeol Lee 1523c599e3 Fixed the SeriesExpansion module so that it is up to date with the current library. Changed const ArrayList to const ArrayList references. 2008-04-19 21:46:39 +00:00
Dongryeol Lee 6a6b321f96 SVD Tree has numerical stability issue when applied to high-dimensional matrices. Going to fix this using orthogonal iteration. 2008-04-19 20:10:40 +00:00
Parikshit Ram 294a820f8e Cover tree files uploaded, tree building coded up, not working, still waiting on dependencies of ArrayList 2008-04-19 10:16:13 +00:00
Dongryeol Lee cdd6a99f92 Updated a potential bug in the ball tree that could attempt to split even if the radius is very close to zero. Changed DBL_MIN to DBL_EPSILON as a result. 2008-04-19 01:28:43 +00:00
Dongryeol Lee 15b9aed1e1 Still need to fix the stitching problem in pca_tree.h 2008-04-18 21:39:01 +00:00
