[scikit-learn] Using GPU in scikit learn

[Tommy Tracy]

Dear Ta Hoang,

Accelerating decision tree ensembles (including Random Forest) is actually
a current area of computer architecture research; in fact it is a principle
component of my dissertation. Like Sebastian Raschka said, the GPU is not
an ideal architecture for decision tree inference because at its core it is
a pointer-chasing algorithm (low computation per memory access) that shows
low memory locality. Scikit-Learn has done an excellent job with their von
Neumann implementation utilizing things like predication and vectorization.
If you're looking to go beyond what the CPU can give you, I would point you
to FPGAs. If you're interested in discussing this further, let me know.
