NettetBetween SVC and LinearSVC, one important decision criterion is that LinearSVC tends to be faster to converge the larger the number of samples is. This is due to the fact that … Nettetmax_iter: 最大迭代次数，默认是-1，即没有限制。 这个是硬限制，它的优先级要高于tol参数，不论训练的标准和精度达到要求没有，都要停止训练。 decision_function_shape ： 原始的SVM只适用于二分类问题，如果要将其扩展到多类分类，就要采取一定的融合策略，这里提供了三种选择。
