注意:我不是说可以通过“get_params”或“set_params”访问的参数。我指的是作为算法结果确定的实际系数。来自SVC文档:
Attributes:
support_ : array-like, shape = [n_SV]
Indices of support vectors.
support_vectors_ : array-like, shape = [n_SV, n_features]
Support vectors.
n_support_ : array-like, dtype=int32, shape = [n_class]
Number of support vectors for each class.
dual_coef_ : array, shape = [n_class-1, n_SV]
Coefficients of the support vector in the decision function. For
multiclass, coefficient for all 1-vs-1 classifiers. The layout of
the coefficients in the multiclass case is somewhat non-trivial.
See the section about multi-class classification in the SVM
section of the User Guide for details.
coef_ : array, shape = [n_class-1, n_features]
Weights assigned to the features (coefficients in the primal
problem). This is only available in the case of a linear
kernel.
coef_ is a readonly property derived from dual_coef_ and
support_vectors_.
intercept_ : array, shape = [n_class * (n_class-1) / 2]
Constants in decision function.
可以从该属性派生有关模型的所有信息
例如:clf.n\u支持
将返回模型的n\u支持
