Type of covariation matrices

Variants

COV_MAT_SPHERICAL = 0

A scaled identity matrix . There is the only parameter to be estimated for each matrix. The option may be used in special cases, when the constraint is relevant, or as a first step in the optimization (for example in case when the data is preprocessed with PCA). The results of such preliminary estimation may be passed again to the optimization procedure, this time with covMatType=EM::COV_MAT_DIAGONAL.

COV_MAT_DIAGONAL = 1

A diagonal matrix with positive diagonal elements. The number of free parameters is d for each matrix. This is most commonly used option yielding good estimation results.

COV_MAT_GENERIC = 2

A symmetric positively defined matrix. The number of free parameters in each matrix is about . It is not recommended to use this option, unless there is pretty accurate initial estimation of the parameters and/or a huge number of training samples.

Trait Implementations

impl Clone for EM_Types

fn clone(&self) -> EM_Types

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EM_Types

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

Formats the value using the given formatter.

impl From<EM_Types> for i32

fn from(v: EM_Types) -> Self

Converts to this type from the input type.

impl PartialEq for EM_Types

fn eq(&self, other: &EM_Types) -> 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 TryFrom<i32> for EM_Types

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
