Struct SvmProblem 

pub struct SvmProblem {
    pub labels: Vec<f64>,
    pub instances: Vec<Vec<SvmNode>>,
}

A training/test problem: a collection of labelled sparse instances.

load_problem validates that sparse feature indices are ascending and within the configured crate::io::LoadOptions bounds. When constructing a problem manually, keep labels.len() == instances.len() and use ascending feature indices to match LIBSVM input assumptions.

Fields

labels: Vec<f64>

Label (class for classification, target for regression) per instance.

instances: Vec<Vec<SvmNode>>

Sparse feature vectors, one per instance.

Trait Implementations

impl Clone for SvmProblem

fn clone(&self) -> SvmProblem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SvmProblem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SvmProblem

fn eq(&self, other: &SvmProblem) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
