NettetLinearSVCとLogisticRegression: C 小さいと単純なモデル; alpha、Cは対数スケールで調整する。 正則化を行う場合はL1かL2かも重要なポイント。 一部のパラメータが重要と予想される: L1 パラメータを限定できるので、モデルを説明しやすくなる。 Nettetfrom sklearn.datasets import make_classification from sklearn.svm import LinearSVC from sklearn.model_selection import GridSearchCV RANDOM_STATE = 123 class LinearSVCSub (LinearSVC): def __init__ (self, penalty='l2', loss='squared_hinge', additional_parameter1=1, additional_parameter2=100, dual=True, tol=0.0001, C=1.0, …

NettetThe linear models LinearSVC () and SVC (kernel='linear') yield slightly different decision boundaries. This can be a consequence of the following differences: LinearSVC minimizes the squared hinge loss while SVC minimizes the regular hinge loss. Nettet我们将举出《统计学习方法》李航著的原始问题例题和对偶问题的例题,接着用LinearSVC实现这个例题,最后将自己编写一个损失函数形式的示例代码来更清晰看到损失函数梯度下降法的求解过程。. 首先再对LinearSVC说明几点:(1)LinearSVC是对liblinear LIBLINEAR -- A ...
Nettet同时,在上一节绘制超平面和边界距离的函数plot_svc_decision_boundary中,我们使用了svm_clf.support_vectors_来获取支持向量点,svm_clf是由SVC函数训练出来的,然而在我们刚刚使用的是LinearSVC函数训练模型,而LinearSVC对象是没有.support_vectors_属性(即支持向量点),所以我们需要自己来定义。
