Struct petal_decomposition::FastIcaBuilder

pub struct FastIcaBuilder<R> { /* private fields */ }

Builder for FastIca.

Examples

use petal_decomposition::FastIcaBuilder;

let x = ndarray::arr2(&[[0_f64, 0_f64], [1_f64, 1_f64]]);
let mut ica = FastIcaBuilder::new().build();
ica.fit(&x);

Implementations

impl FastIcaBuilder<Pcg>

pub fn new() -> Self

Sets the number of components for PCA.

It uses a PCG random number generator (the XSL 128/64 (MCG) variant on a 64-bit CPU and the XSH RR 64/32 (LCG) variant on a 32-bit CPU), initialized with a randomly-generated seed.

pub fn seed(self, seed: u128) -> Self

Initialized the PCG random number genernator with the given seed.

Examples

use petal_decomposition::FastIcaBuilder;

let x = ndarray::arr2(&[[0_f64, 0_f64], [1_f64, 1_f64]]);
let mut ica = FastIcaBuilder::new().seed(1234567891011121314).build();
ica.fit(&x);

impl<R: Rng> FastIcaBuilder<R>

pub fn with_rng(rng: R) -> Self

Sets the random number generator for FastICA.

Examples

use petal_decomposition::FastIcaBuilder;
use rand_pcg::Pcg64;

let x = ndarray::arr2(&[[0_f64, 0_f64], [1_f64, 1_f64]]);
let rng = Pcg64::new(0xcafef00dd15ea5e5, 0xa02bdbf7bb3c0a7ac28fa16a64abf96);
let mut ica = FastIcaBuilder::with_rng(rng).build();
ica.fit(&x);

pub fn build<A: Scalar>(self) -> FastIca<A, R>

Creates an instance of FastIca.

Trait Implementations

impl Default for FastIcaBuilder<Pcg>

fn default() -> Self

Returns the “default value” for a type.
