In turn, that enables working more efficiently with data sets that were written separately. * Implement Dataset.dump_text, and fix small bug in appending of group bin boundaries. Dumping to text enables us to compare results, without having to worry about issues like features being reordered. * Add basic tests for validation logic for add_features_from. * Remove various internal mapping items from dataset text dumps These are too sensitive to the exact feature order chosen, which is not visible to the user. Including them in tests appears unnecessary, as the data dumping code should provide enough coverage. * Add test that add_features_from results in identical data sets according to dump_text. * Add test that booster behaviour after using add_features_from matches that of training on the full data This checks: - That training after add_features_from works at all - That add_features_from does not cause training to misbehave * Expose feature_penalty and monotone_types/constraints via get_field These getters allow us to check that add_features_from does the right thing with these vectors. * Add tests that add_features correctly handles feature_penalty and monotone_constraints. * Ensure add_features_from properly frees the added dataset and add unit test for this Since add_features_from moves the feature group pointers from the added dataset to the dataset being added to, the added dataset is invalid after the call. We must ensure we do not try and access this handle. * Remove some obsolete TODOs * Tidy up DumpTextFile by using a single iterator for each feature This iterators were also passed around as raw pointers without being freed, which is now fixed. * Factor out offsetting logic in AddFeaturesFrom * Remove obsolete TODO * Remove another TODO This one is debatable, test code can be a bit messy and duplicate-heavy, factoring it out tends to end badly. Leaving this for now, will revisit if adding more tests later on becomes a mess. * Add documentation for newly-added methods. * Initial work towards add_data_from This currently only merges the feature groups and updates num_data_. It does not deal with Metadata or non-dense bins yet. * Fix bug where dense bin copy of num_data_ wasn't updated * Small bug fix in dense_bin.hpp, initial implementation of Merge for 4-bits bin. * Add unit test for dense bin case of add_data_from, and refactor tests slightly. * Initial implementation of Merge for sparse bins and unit tests for it. * Ensure we test merging sparse data sets after loading them from binary This seems silly, but push_buffers_ aren't populated if the data was loaded from a binary file. This forces us to reconstruct the index,value form of the data in the target bin before merging. Adding this test ensures that code is covered. * Add labels to text dumps. * Add weights to text dumps. * Ensure add_data_from properly merges labels. * Ensure metadata appends weights correctly, and unit test for it. * Implement metadata merging for query bits This is currently not covered by unit tests. * Check datasets are aligned before merging. This catches the majority of obvious errors, e.g. not having the same number of features or having different bin mappings. * Add test that booster behaviour is preserved by add_data_from. * Add configuration parameters for CEGB. * Add skeleton CEGB tree learner Like the original CEGB version, this inherits from SerialTreeLearner. Currently, it changes nothing from the original. * Track features used in CEGB tree learner. * Pull CEGB tradeoff and coupled feature penalty from config. * Implement finding best splits for CEGB This is heavily based on the serial version, but just adds using the coupled penalties. * Set proper defaults for cegb parameters. * Ensure sanity checks don't switch off CEGB. * Implement per-data-point feature penalties in CEGB. * Implement split penalty and remove unused parameters. * Merge changes from CEGB tree learner into serial tree learner * Represent features_used_in_data by a bitset, to reduce the memory overhead of CEGB, and add sanity checks for the lengths of the penalty vectors.
