Nettet首先再对LinearSVC说明几点：（1）LinearSVC是对liblinear LIBLINEAR -- A Library for Large Linear Classification 的封装（2）liblinear中使用的是损失函数形式来定义求解最优超平面的，因此类初始化参数都是损失函数形式需要的参数。（3）原始形式、对偶形式、损失函数形式是等价的，有关于三者之间的关系以及证明可以参考《统计学习方法 … NettetThe ‘l1’ leads to coef_ vectors that are sparse. Specifies the loss function. ‘hinge’ is the standard SVM loss (used e.g. by the SVC class) while ‘squared_hinge’ is the square of the hinge loss. Select the algorithm to either solve the dual or primal optimization problem. Prefer dual=False when n_samples > n_features.
