Struct Hyperparameters

pub struct Hyperparameters { /* private fields */ }

Hyperparameters for the SVC model.

Implementations

impl Hyperparameters

pub fn new( dim: usize, kernel: KernelType, num_classes: usize, ) -> Hyperparameters

pub fn C(&mut self, C: f64) -> &mut Hyperparameters

Set the regularization parameter C; smaller values mean more regularization. Default is 1.0.

pub fn degree(&mut self, degree: i32) -> &mut Hyperparameters

Set the degree of the polynomial kernel. No effect on other kernels. Default: 3.

pub fn gamma(&mut self, gamma: f64) -> &mut Hyperparameters

Set the gamma parameter of the RBF kernel. Default is 1 / self.dim.

pub fn coef0(&mut self, coef0: f64) -> &mut Hyperparameters

Set the coef0 parameter for the sigmoid kernel. Default is 0.0.

pub fn cache_size(&mut self, cache_size: f64) -> &mut Hyperparameters

Set the libsvm cache size, in megabytes. Default is 100.0.

pub fn build(&self) -> SVC

Build the SVC model. libsvm natively supports multiclass problems via one-vs-one (OvO) estimation, so no one-vs-rest wrapper is provided.

Trait Implementations

impl Clone for Hyperparameters

fn clone(&self) -> Hyperparameters

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'de> Deserialize<'de> for Hyperparameters

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Hyperparameters

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
