R parsnip svm_linear 线性支持向量机svm_linear() 定义支持向量机模型。对于分类,模型尝试最大化类之间的边距宽度(使用线性类边界)。对于回归,模型优化了一个稳健的损失函数,该函数仅受非常大的模型残差的影响,并使用线性拟合。该函数可以拟合分类和回归模型。 拟合该模型的方法有多种,通过设置模型引擎来选择估计...

I have this dataset:https://www.kaggle.com/datasets/mirbektoktogaraev/should-this-loan-be-approved-or-deniedfrom which I have removed all instances where NewExist = 1 and all instances containing NA values. I have also removed the ChgOffPrinGr column, so I have 161,732 ...
Support vector machines (SVM) are a powerful tool to analyze data with a number of predictors approximately equal or larger than the number of observations. However, originally, application of SVM to analyze biomedical data was limited because SVM was no
