importance in SVM, unless a linear kernel is used. Refer following answer for more information. It's recommended to use feature extraction or dimensionality reduction techniques instead of SVM.https://se.mathwo
5、LinearSVC基于liblinear,罚函数是对截矩进行惩罚;SVC基于libsvm,罚函数不是对截矩进行惩罚。 6、我们知道SVM解决问题时,问题是分为线性可分和线性不可分问题的,liblinear对线性可分问题做了优化,故在大量数据上收敛速度比libsvm快 (一句话,大规模线性可分问题上LinearSVC更快) 7、为什么中国没有stackoverflow这...

具有参考价值。在Andrew NG的课里讲到过:1. 如果Feature的数量很大,跟样本数量差不多,这时候选用LR或者是Linear Kernel的SVM 2. 如果Feature的数量比较小,样本数量一般,不算大也不算小,选用SVM+Gaussian Kernel 3. 如果Feature的数量比较小,而样本数量很多,需要手工添加一些feature变成第一种情况 还是...

错误消息 "AttributeError: coef_ is only available when using a linear kernel svm_model.fit(X, temperature)" 意味着您尝试在使用非线性内核(如RBF或多项式内核)的支持向量机(SVM)模型上访问coef_属性,但该属性只对线性内核有效。 在SVM中,coef_属性用于获取线性内核的系数。这些系数表示了特征的权重。然而,...

In SVM we can classify data using non-linear boundary without the manual feature engineering step. There is still a HyperParameter for the kernel type to set, but you will mostly have few options to choose from. This also helps to establish a baseline for your model. Learning Curve...
