* add parameter data_sample_strategy * abstract GOSS as a sample strategy(GOSS1), togetherwith origial GOSS (Normal Bagging has not been abstracted, so do NOT use it now) * abstract Bagging as a subclass (BAGGING), but original Bagging members in GBDT are still kept * fix some variables * remove GOSS(as boost) and Bagging logic in GBDT * rename GOSS1 to GOSS(as sample strategy) * add warning about use GOSS as boosting_type * a little ; bug * remove CHECK when "gradients != nullptr" * rename DataSampleStrategy to avoid confusion * remove and add some ccomments, followingconvention * fix bug about GBDT::ResetConfig (ObjectiveFunction inconsistencty bet… * add std::ignore to avoid compiler warnings (anpotential fails) * update Makevars and vcxproj * handle constant hessian move resize of gradient vectors out of sample strategy * mark override for IsHessianChange * fix lint errors * rerun parameter_generator.py * update config_auto.cpp * delete redundant blank line * update num_data_ when train_data_ is updated set gradients and hessians when GOSS * check bagging_freq is not zero * reset config_ value merge ResetBaggingConfig and ResetGOSS * remove useless check * add ttests in test_engine.py * remove whitespace in blank line * remove arguments verbose_eval and evals_result * Update tests/python_package_test/test_engine.py reduce num_boost_round Co-authored-by: James Lamb <jaylamb20@gmail.com> * Update tests/python_package_test/test_engine.py reduce num_boost_round Co-authored-by: James Lamb <jaylamb20@gmail.com> * Update tests/python_package_test/test_engine.py reduce num_boost_round Co-authored-by: James Lamb <jaylamb20@gmail.com> * Update tests/python_package_test/test_engine.py reduce num_boost_round Co-authored-by: James Lamb <jaylamb20@gmail.com> * Update tests/python_package_test/test_engine.py reduce num_boost_round Co-authored-by: James Lamb <jaylamb20@gmail.com> * Update tests/python_package_test/test_engine.py reduce num_boost_round Co-authored-by: James Lamb <jaylamb20@gmail.com> * Update src/boosting/sample_strategy.cpp modify warning about setting goss as `boosting_type` Co-authored-by: James Lamb <jaylamb20@gmail.com> * Update tests/python_package_test/test_engine.py replace load_boston() with make_regression() remove value checks of mean_squared_error in test_sample_strategy_with_boosting() * Update tests/python_package_test/test_engine.py add value checks of mean_squared_error in test_sample_strategy_with_boosting() * Modify warnning about using goss as boosting type * Update tests/python_package_test/test_engine.py add random_state=42 for make_regression() reduce the threshold of mean_square_error * Update src/boosting/sample_strategy.cpp Co-authored-by: James Lamb <jaylamb20@gmail.com> * remove goss from boosting types in documentation * Update src/boosting/bagging.hpp Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Update src/boosting/bagging.hpp Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Update src/boosting/goss.hpp Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Update src/boosting/goss.hpp Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * rename GOSS with GOSSStrategy * update doc * address comments * fix table in doc * Update include/LightGBM/config.h Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * update documentation * update test case * revert useless change in test_engine.py * add tests for evaluation results in test_sample_strategy_with_boosting * include <string> * change to assert_allclose in test_goss_boosting_and_strategy_equivalent * more tolerance in result checking, due to minor difference in results of gpu versions * change == to np.testing.assert_allclose * fix test case * set gpu_use_dp to true * change --report to --report-level for rstcheck * use gpu_use_dp=true in test_goss_boosting_and_strategy_equivalent * revert unexpected changes of non-ascii characters * revert unexpected changes of non-ascii characters * remove useless changes * allocate gradients_pointer_ and hessians_pointer when necessary * add spaces * remove redundant virtual * include <LightGBM/utils/log.h> for USE_CUDA * check for in test_goss_boosting_and_strategy_equivalent * check for identity in test_sample_strategy_with_boosting * remove cuda option in test_sample_strategy_with_boosting * Update tests/python_package_test/test_engine.py Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Update tests/python_package_test/test_engine.py Co-authored-by: James Lamb <jaylamb20@gmail.com> * ResetGradientBuffers after ResetSampleConfig * ResetGradientBuffers after ResetSampleConfig * ResetGradientBuffers after bagging * remove useless code * check objective_function_ instead of gradients * enable rf with goss simplify params in test cases * remove useless changes * allow rf with feature subsampling alone * change position of ResetGradientBuffers * check for dask * add parameter types for data_sample_strategy Co-authored-by: Guangda Liu <v-guangdaliu@microsoft.com> Co-authored-by: Yu Shi <shiyu_k1994@qq.com> Co-authored-by: GuangdaLiu <90019144+GuangdaLiu@users.noreply.github.com> Co-authored-by: James Lamb <jaylamb20@gmail.com> Co-authored-by: Nikita Titov <nekit94-08@mail.ru>
