Trait LibLinearProblem

pub trait LibLinearProblem: Clone {
    // Required methods
    fn source_features(&self) -> &[Vec<FeatureNode>];
    fn target_values(&self) -> &[f64];
    fn bias(&self) -> f64;
}

Represents a one-to-one mapping of source features to target values.

Source features are represented as sparse vectors of real numbers. Target values are either integers (in classification) or real numbers (in regression).

Required Methods

fn source_features(&self) -> &[Vec<FeatureNode>]

The feature vectors of each training instance.

fn target_values(&self) -> &[f64]

Target labels/values of each training instance.

fn bias(&self) -> f64

Bias of the input data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
