Struct DiffusionMapParams

pub struct DiffusionMapParams(/* private fields */);
Expand description

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§

Source§

impl DiffusionMapParams

Source

pub fn steps(self, steps: usize) -> Self

Set the number of steps in the diffusion operator

The diffusion map algorithm expresses the transition probability with a kernel matrix and then takes multiple steps along the diffusion operator. In practice scales the eigenvalues of the decomposition exponentially with the number of steps.

Source

pub fn embedding_size(self, embedding_size: usize) -> Self

Source

pub fn new(embedding_size: usize) -> DiffusionMapParams

Creates the set of default parameters

§Parameters
  • embedding_size: the number of dimensions in the projection
§Returns

Parameter set with number of steps = 1
