Struct linfa_reduction::DiffusionMapValidParams

pub struct DiffusionMapValidParams { /* private fields */ }

Diffusion map hyperparameters

The diffusion map algorithms has only two explicit hyperparameter. The first is the stepsize. As the algorithm calculates the closeness of points after a number of steps taken in the diffusion graph, a larger step size introduces a more global behaviour of the projection while a smaller one (especially one) just projects close obserations closely together. The second parameter is the embedding size and defines the target dimensionality.

Implementations

impl DiffusionMapValidParams

pub fn steps(&self) -> usize

pub fn embedding_size(&self) -> usize

Trait Implementations

impl Clone for DiffusionMapValidParams

fn clone(&self) -> DiffusionMapValidParams

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiffusionMapValidParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<DiffusionMapValidParams> for DiffusionMapValidParams

fn eq(&self, other: &DiffusionMapValidParams) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
