通常情况下,我们会将已有的数据分为两部分:训练集 (training set) 和测试集 (test set)。使用训练集来训练模型,并用测试集的数据来评估模型性能。这个过程叫做交叉验证(cross-validation)。常见的交叉验证方法有以下三种: Hold-out cross-validation. k-fold cross-validation. ...
install.packages("mlr")之后就可以看到R里面有哪些机器学习算法、在哪个包里面。 a<-listLearners() 这个包是听CDA网络课程《R语言与机器学习实战》余文华老师所述,感觉很棒,有待以后深入探讨。以下表格是R语言里面,52个机器学习算法的来源以及一些数据要求。
这是我在代码方面所做的: ## Create training, validation and test taskstrain_task<-makeClassifTask(data=train_data,target="y",positive=1)validation_task<-makeClassifTask(data=validation_data,target="y")test_task<-makeClassifTask(data=test_data,target="y")## Attempt to tune parameters with s...
Hyperparameters are parameters that are not directly learned by the model during training but can significantly impact the performance of the model. 在数据分析中,MLR(多元线性回归)是一种常用的统计技术。它是一种建模依赖变量与一个或多个自变量之间关系的方法。MLR是一种强大的工具,可用于预测结果并理解...
