为了用最简单的形式实现剪枝算法,Optuna为以下库提供了集成模块。关于Optuna集成模块的完整列表,参见optuna.integration.比如,XGBoostPruningCallback在没有改变训练迭代过程的逻辑的情况下引入了剪枝。 pruning_callback = optuna.integration.XGBoostPruningCallback(trial,'validation-error') ...
其中,“optuna.integration.lightgbm.train” 提供了对超参数的高效逐步调整,可用于直接取代 “ lightgbm.train”,因而用户无需修改代码。 而为了与其他Optuna组件进行交叉验证和集成,例如记录优化历史记录和分布式部署的研究,Optuna还提供了`optuna.integration.lightgbm.LightGBMTuner`和`optuna.integration.lightgbm.LightGBM...
