Struct GaussCPDP 

pub struct GaussCPDP { /* private fields */ }

Parameters of a Gaussian CPD.

Implementations

impl GaussCPDP

pub fn new(a: Array2<f64>, b: Array1<f64>, s: Array2<f64>) -> Self

Creates a new GaussCPDP instance.

Arguments

• a - Coefficient matrix |X| x |Z|.
• b - Intercept vector |X|.
• s - Covariance matrix |X| x |X|.

Panics

• Panics if the number of rows of a does not match the size of b.
• Panics if the number of rows of a does not match the size of s.
• Panics if s is not square and symmetric.
• Panics if any of the values in a, b, or s are not finite.

Returns

A new GaussCPDP instance.

pub const fn coefficients(&self) -> &Array2<f64>

Returns the coefficient matrix |X| x |Z|.

Returns

A reference to the coefficient matrix.

pub const fn intercept(&self) -> &Array1<f64>

Returns the intercept vector |X|.

Returns

A reference to the intercept vector.

pub const fn covariance(&self) -> &Array2<f64>

Returns the covariance matrix |X| x |X|.

Returns

A reference to the covariance matrix.

Trait Implementations

impl AbsDiffEq for GaussCPDP

type Epsilon = f64

Used for specifying relative comparisons.

fn default_epsilon() -> Self::Epsilon

The default tolerance to use when testing values that are close together.

fn abs_diff_eq(&self, other: &Self, epsilon: Self::Epsilon) -> bool

A test for equality that uses the absolute difference to compute the approximate equality of two numbers.

fn abs_diff_ne(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool

The inverse of AbsDiffEq::abs_diff_eq.

impl Clone for GaussCPDP

fn clone(&self) -> GaussCPDP

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GaussCPDP

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GaussCPDP

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GaussCPDP

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl RelativeEq for GaussCPDP

fn default_max_relative() -> Self::Epsilon

The default relative tolerance for testing values that are far-apart.

fn relative_eq( &self, other: &Self, epsilon: Self::Epsilon, max_relative: Self::Epsilon, ) -> bool

A test for equality that uses a relative comparison if the values are far apart.

fn relative_ne( &self, other: &Rhs, epsilon: Self::Epsilon, max_relative: Self::Epsilon, ) -> bool

The inverse of RelativeEq::relative_eq.

impl Serialize for GaussCPDP

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
