WebLinearSVC has no support for probabilities, while SVC does. Now some additional remarks: SVM-theory is not much about probabilities and the support for this comes from extra-approaches using cross-validation and an additional classifier . see Platt scaling; the core-solver of LinearSVC, liblinear has not inbuilt-support for this WebLinearSVC 是一种线性支持向量机分类器，也是建立在 SVM 的基础之上的。 它与 SVC 的区别在于 LinearSVC 是线性的，所以它只能处理线性可分的数据。 相比之下，SVC 可以处理非线性可分的数据，因为它可以使用核函数将数据转换成线性可分的形式。 company office furniture https://pspoxford.com
