Struct AmplitudePhasePerturbation

pub struct AmplitudePhasePerturbation {
    pub name: String,
    pub magnitude_std: f64,
    pub phase_std: f64,
    pub is_time_domain: bool,
    /* private fields */
}

This augmenter perturbs the frequency representation of each time series by adding Gaussian noise to the magnitude and phase of each frequency bin. If is_time_domain is true, the input is first transformed to the frequency domain using FFT, the perturbation is applied, and then the result is transformed back to the time domain using IFFT. The standard deviations of the noise for magnitude and phase are controlled by magnitude_std and phase_std, respectively.

Trait Implementations

impl Augmenter for AmplitudePhasePerturbation

fn augment_batch(&self, data: &mut Dataset, _parallel: bool, per_sample: bool)

Augment a whole batch

fn augment_one(&self, x: &[f64]) -> Vec<f64>

Augment one time series

fn get_probability(&self) -> f64

Get the probability that this augmenter will augment a series in a batch

fn set_probability(&mut self, probability: f64)

By setting a probability with this function the augmenter will only augment a series in a batch with the specified probability

fn get_name(&self) -> String

fn supports_per_sample(&self) -> bool

Indicate whether this augmenter supports per-sample chaining. By default, return true. Augmenters that need a batch level view should override this to return false.
