* Fix warnings when compiled with -pedantic
* add -DBOOST_ALL_NO_LIB for windows build
* fix some more MSVC warnings
* Break OpenCL string literal to smaller pieces to avoid error C2026 of MSVC
The string was longer than the limit of 16380 single-byte characters.
This affects Visual Studio 2005 - 2015. Untested on VS 2017.
* Revert "python-package: support valid_names in scikit-learn API (#420)"
This reverts commit de39dbcf3d.
* Revert "faster histogram sum up (#418)"
This reverts commit 98c7c2a35a.
* some refactor.
* two stage sum up to reduce sum up error.
* add more two-stage sumup.
* some refactor.
* add alignment.
* change name to aligned_allocator.
* remove some useless sumup.
* fix a warning.
* add -march=native .
* remove the padding of gradients.
* no alignment.
* fix test.
* change KNumSumupGroup to 32768.
* change gcc flags.
* fix the size of vector cnt_per_class
* put Boost.Compute includes at the beginning
We want to put the submodule Boost.Compute at the beginning of compiler search
paths, because the submodule usually contains upstream bug fixes that have not
been included in the stable Boost releases installed on the host OS.

* fix boost version in CMakeList
* Add a README
* reconstruct GPU initialization code for ResetTrainingData
* move data to GPU in parallel
* fix a bug during feature copy
* update gpu kernels
* update gpu code
* initial port to LightGBM v2
* speedup GPU data loading process
* Add 4-bit bin support to GPU
* re-add sparse_threshold parameter
* remove kMaxNumWorkgroups and allows an unlimited number of features
* add feature mask support for skipping unused features
* enable kernel cache
* use GPU kernels withoug feature masks when all features are used
* REAdme.
* REAdme.
* update README
* fix typos (#349)
* change compile to gcc on Apple as default
* clean vscode related file
* refine api of constructing from sampling data.
* fix bug in the last commit.
* more efficient algorithm to sample k from n.
* fix bug in filter bin
* change to boost from average output.
* fix tests.
* only stop training when all classes are finshed in multi-class.
* limit the max tree output. change hessian in multi-class objective.
* robust tree model loading.
* fix test.
* convert the probabilities to raw score in boost_from_average of classification.
* fix the average label for binary classification.
* Add boost_from_average to docs (#354)
* don't use "ConvertToRawScore" for self-defined objective function.
* boost_from_average seems doesn't work well in binary classification. remove it.
* For a better jump link (#355)
* Update Python-API.md
* for a better jump in page
A space is needed between `#` and the headers content according to Github's markdown format [guideline](https://guides.github.com/features/mastering-markdown/)
After adding the spaces, we can jump to the exact position in page by click the link.
