Struct MultiClassSVM 

Source 
pub struct MultiClassSVM<const D: usize, K, C>
where
    K: Kernel<D>,
    C: Eq + Hash + Clone,
{ /* private fields */ }
Expand description

A fitted multi-class classification support vector machine using One-vs-One strategy.

§Type Parameters

  • D - The dimension or number of features.
  • K - The type of the kernel function.
  • C - The type of the class label.

§Strategy

Uses One-vs-One (OvO) approach: trains a binary classifier for each pair of classes. For N classes, trains N*(N-1)/2 binary classifiers. Prediction is done by majority voting.
