Struct LecunNormal 

pub struct LecunNormal { /* private fields */ }

LecunNormal is a truncated normal distribution centered at 0 with a standard deviation that is calculated as σ = sqrt(1/n_in) where n_in is the number of input units.

Implementations

impl LecunNormal

pub fn new(n: usize) -> LecunNormal

pub fn distr<F>(&self) -> Result<TruncatedNormal<F>, Error>

where F: Float, StandardNormal: Distribution<F>,

Create a truncated normal distribution centered at 0; See Self::std_dev for the standard deviation calculations.

pub fn std_dev<F>(&self) -> F

where F: Float,

Calculate the standard deviation (σ) of the distribution. This is done by computing the root of the reciprocal of the number of inputs

Symbolically: σ = sqrt(1/n)

Trait Implementations

Formats the value using the given formatter.

impl<F> Distribution<F> for LecunNormal

where F: Float, StandardNormal: Distribution<F>,

fn sample<R>(&self, rng: &mut R) -> F

where R: Rng + ?Sized,

Generate a random value of T, using rng as the source of randomness.

impl Ord for LecunNormal

fn cmp(&self, other: &LecunNormal) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
