Struct PrecisionRecallCurve 

pub struct PrecisionRecallCurve {
    pub precision_values: Option<FloatVector>,
    pub precision_confidence_thresholds: Option<FloatVector>,
    pub recall_values: Option<FloatVector>,
    pub recall_confidence_thresholds: Option<FloatVector>,
}

Precision/Recall curve.

The syntax comprises two tables, one to look up the confidence value threshold for a given precision, and the other for a given recall.

Example: –––––––––––+––+––+––+––+––+––+––+––+–– precisionValues | .1 | .2 | .3 | .4 | .5 | .6 | .7 | precisionConfidence | .0 | .0 | .0 | .0 | .1 | .3 | .4 | –––––––––––+––+––+––+––+––+––+––+––+––

–––––––––––+––+––+––+––+––+––+––+––+–– recallValues | .1 | .2 | .3 | .4 | .5 | .6 | .7 | .8 | .9 recallConfidence | .7 | .6 | .5 | .4 | .3 | .3 | .2 | .1 | .0 –––––––––––+––+––+––+––+––+––+––+––+––

The application expects that, when it filters out samples with confidence threshold = 0.1, it gets precision = 0.5. Likewise, with threshold = 0.2 it gets recall = 0.7.

The table must have only valid values; do not use NaN, +/- INF, or negative values. The application is responsible for inter/extrapolating approprate confidence threshold based on the application’s specific need.

Trait Implementations

impl Clone for PrecisionRecallCurve

fn clone(&self) -> PrecisionRecallCurve

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrecisionRecallCurve

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

Formats the value using the given formatter.

impl Default for PrecisionRecallCurve

fn default() -> Self

Returns the “default value” for a type.

impl Message for PrecisionRecallCurve

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 PrecisionRecallCurve

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