Struct SvmProblem

Source

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

Expand description

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.
