Struct KNearestNeighborsClassifier 

pub struct KNearestNeighborsClassifier {
    pub nearest_neighbors_index: Option<NearestNeighborsIndex>,
    pub number_of_neighbors: Option<Int64Parameter>,

    pub default_class_label: Option<DefaultClassLabel>,

}

A k-Nearest-Neighbor classifier

Fields

nearest_neighbors_index: Option<NearestNeighborsIndex>

The “core” nearest neighbor model attributes.

number_of_neighbors: Option<Int64Parameter>

Number of neighbors to use for classification.

class_labels: Option<ClassLabels>

Type of labels supported by the model. Currently supports String or Int64 labels.

default_class_label: Option<DefaultClassLabel>

Default value of class label (useful when prediction is called on an empty kNN classifier)

weighting_scheme: Option<WeightingScheme>

Weighting scheme to be used when computing the majority label of a new data point.

Trait Implementations

impl Clone for KNearestNeighborsClassifier

fn clone(&self) -> KNearestNeighborsClassifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KNearestNeighborsClassifier

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

Formats the value using the given formatter.

impl Default for KNearestNeighborsClassifier

fn default() -> Self

Returns the “default value” for a type.

impl Message for KNearestNeighborsClassifier

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 KNearestNeighborsClassifier

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