Struct GpRegressor &nbsp; Copy item path

impl GpRegressor

pub fn fit( x: &[f64], y: &[f64], n: usize, p: usize, length_scale: f64, signal_var: f64, noise_var: f64, ) -> Result<Self, LearningError>

Fit a GP with squared-exponential kernel (length_scale ℓ, signal_var σ²_f) and Gaussian noise noise_var σ²ₙ. Fails closed on shape mismatch / non-positive hyper-parameters / a non-PD kernel matrix.

pub fn noise_variance(&self) -> f64

Training noise variance σ²ₙ used when fitting the regressor.

pub fn predict_row(&self, x_star: &[f64]) -> (f64, f64)

Predictive distribution at one input: (mean, variance). The variance includes the model uncertainty (small near training data, large away from it).

pub fn predict(&self, x: &[f64], m: usize) -> Vec<(f64, f64)>

Predictive (mean, variance) for each row of a row-major m × p matrix.
