Pipeline(memory=None,
steps=[(‘std_scaler’, StandardScaler(copy=True, with_mean=True, with_std=True)), (‘kernelSVC’, SVC(C=1.0, cache_size=200, class_weight=None, coef0=0.0,
decision_function_shape=‘ovr’, degree=3, gamma=1.0, kernel=‘rbf’,
max_iter=-1, probability=False, random_state=None, shrinking=True,
tol=0.001, verbose=False))])
这是使用rfb的svc 请问里面的degree=3,是什么意思,对于核函数其degree如何确定
