在代码中,X是包含所有特征的数据集,y是目标变量的值。使用train_test_split将数据集划分为训练集和测试集。然后,使用RandomForestRegressor构建随机森林回归模型,并使用fit函数在训练集上拟合模型。最后,使用predict函数在测试集上做预测,并使用mean_squared_error和r2_score函数评估模型的预测性能。 四、R语言实现随机...

The CFD modeling could accurately predict the features of the fluid flow18,19,20. These predictions are helpful to prevent the costs coming from the try and error during the experiments. In addition, a number of the flow features cannot be achieved by the experimental measurements (e.g. veloc...
