      Add Cost Effective Gradient Boosting (#2014) · 76102284
      remcob-gr authored
      * 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.
      
      * Fix bug where CEGB would incorrectly penalise a previously used feature
      
      The tree learner did not update the gains of previously computed leaf splits when splitting a leaf elsewhere in the tree.
      This caused it to prefer new features due to incorrectly penalising splitting on previously used features.
      
      * Document CEGB parameters and add them to the appropriate section.
      
      * Remove leftover reference to cegb tree learner.
      
      * Remove outdated diff.
      
      * Fix warnings
      
      * Fix minor issues identified by @StrikerRUS.
      
      * Add docs section on CEGB, including citation.
      
      * Fix link.
      
      * Fix CI failure.
      
      * Add some unit tests
      
      * Fix pylint issues.
      
      * Fix remaining pylint issue
