Struct linfa_svm::hyperparams::SvmValidParams

pub struct SvmValidParams<F: Float, T> { /* private fields */ }

SVM Hyperparameters

The SVM fitting process can be controlled in different ways. For classification the C and Nu parameters control the ratio of support vectors and accuracy, eps controls the required precision. After setting the desired parameters a model can be fitted by calling fit.

You can specify the expected return type with the turbofish syntax. If you want to enable Platt-Scaling for proper probability values, then use:

use linfa_svm::Svm;
use linfa::dataset::Pr;
let model = Svm::<f64, Pr>::params();

or bool if you only wants to know the binary decision:

use linfa_svm::Svm;
let model = Svm::<f64, bool>::params();

Example

use linfa_svm::Svm;
let model = Svm::<_, bool>::params()
    .eps(0.1f64)
    .shrinking(true)
    .nu_weight(0.1)
    .fit(&dataset);
