Struct google_api_proto::google::cloud::bigquery::v2::model::training_run::iteration_result::PrincipalComponentInfo

pub struct PrincipalComponentInfo {
    pub principal_component_id: Option<i64>,
    pub explained_variance: Option<f64>,
    pub explained_variance_ratio: Option<f64>,
    pub cumulative_explained_variance_ratio: Option<f64>,
}

Principal component infos, used only for eigen decomposition based models, e.g., PCA. Ordered by explained_variance in the descending order.

Fields

principal_component_id: Option<i64>

Id of the principal component.

explained_variance: Option<f64>

Explained variance by this principal component, which is simply the eigenvalue.

explained_variance_ratio: Option<f64>

Explained_variance over the total explained variance.

cumulative_explained_variance_ratio: Option<f64>

The explained_variance is pre-ordered in the descending order to compute the cumulative explained variance ratio.

Trait Implementations

impl Clone for PrincipalComponentInfo

fn clone(&self) -> PrincipalComponentInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PrincipalComponentInfo

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

Formats the value using the given formatter.

impl Default for PrincipalComponentInfo

fn default() -> Self

Returns the “default value” for a type.

impl Message for PrincipalComponentInfo

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for PrincipalComponentInfo

fn eq(&self, other: &PrincipalComponentInfo) -> 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.
