### Constructor Parameters
|
||||
|
||||
* $kernel (int) - kernel type to be used in the algorithm (default Kernel::LINEAR)
|
||||
* $kernel (int) - kernel type to be used in the algorithm (default Kernel::RBF)
|
||||
* $cost (float) - parameter C of C-SVC (default 1.0)
|
||||
* $degree (int) - degree of the Kernel::POLYNOMIAL function (default 3)
|
||||
* $gamma (float) - kernel coefficient for ‘Kernel::RBF’, ‘Kernel::POLYNOMIAL’ and ‘Kernel::SIGMOID’. If gamma is ‘null’ then 1/features will be used instead.
