Webclass sklearn.svm.SVR(*, kernel='rbf', degree=3, gamma='scale', coef0=0.0, tol=0.001, C=1.0, epsilon=0.1, shrinking=True, cache_size=200, verbose=False, max_iter=-1) 源码 Epsilon支持向量回归。模型中的自由参数是C和epsilon。该实现基于libsvm。拟合时间的复杂度是样本数量的两倍以上，这使得很难扩展到具有多个10000个样本的数据集。 WebIn principle, you can search for the kernel in GridSearch. But you should keep in mind that 'gamma' is only useful for ‘rbf’, ‘poly’ and ‘sigmoid’. That means You will have redundant calculation when 'kernel' is 'linear'. The better way is to use a list of dictionaries rather than a dictionary as an input parameter of param_grid:
