| cache_size | Specify the size of the kernel cache (in MB)
class_weight : {dict, 'balanced'}, optional
Set the parameter C of class i to class_weight[i]*C for
SVC. If not given, all classes are supposed to have
weight one. The "balanced" mode uses the values of y to automatically
adjust weights inversely proportional to class frequencies as
``n_samples / (n_classes * np.bincount(y))`` | default: 200 |
| class_weight | | default: null |
| coef0 | Independent term in kernel function
It is only significant in 'poly' and 'sigmoid' | default: 0.0 |
| decision_function_shape | Whether to return a one-vs-rest ('ovr') decision function of shape
(n_samples, n_classes) as all other classifiers, or the original
one-vs-one ('ovo') decision function of libsvm which has shape
(n_samples, n_classes * (n_classes - 1) / 2)
.. versionchanged:: 0.19
decision_function_shape is 'ovr' by default
.. versionadded:: 0.17
*decision_function_shape='ovr'* is recommended
.. versionchanged:: 0.17
Deprecated *decision_function_shape='ovo' and None* | default: null |
| degree | Degree of the polynomial kernel function ('poly')
Ignored by all other kernels | default: 3 |
| gamma | Kernel coefficient for 'rbf', 'poly' and 'sigmoid'
Current default is 'auto' which uses 1 / n_features,
if ``gamma='scale'`` is passed then it uses 1 / (n_features * X.var())
as value of gamma. The current default of gamma, 'auto', will change
to 'scale' in version 0.22. 'auto_deprecated', a deprecated version of
'auto' is used as a default indicating that no explicit value of gamma
was passed | default: "auto" |
| kernel | Specifies the kernel type to be used in the algorithm
It must be one of 'linear', 'poly', 'rbf', 'sigmoid', 'precomputed' or
a callable
If none is given, 'rbf' will be used. If a callable is given it is
used to precompute the kernel matrix | default: "linear" |
| max_iter | Hard limit on iterations within solver, or -1 for no limit | default: -1 |
| nu | An upper bound on the fraction of training errors and a lower
bound of the fraction of support vectors. Should be in the
interval (0, 1] | default: 0.3 |
| probability | Whether to enable probability estimates. This must be enabled prior
to calling `fit`, and will slow down that method | default: true |
| random_state | The seed of the pseudo random number generator used when shuffling
the data for probability estimates. If int, random_state is the seed
used by the random number generator; If RandomState instance,
random_state is the random number generator; If None, the random
number generator is the RandomState instance used by `np.random`. | default: 3 |
| shrinking | Whether to use the shrinking heuristic | default: true |
| tol | Tolerance for stopping criterion | default: 3.241909264428642e-05 |
| verbose | Enable verbose output. Note that this setting takes advantage of a
per-process runtime setting in libsvm that, if enabled, may not work
properly in a multithreaded context | default: false |
