Struct RougeLScore 

pub struct RougeLScore { /* private fields */ }

ROUGE-L metric based on longest common subsequence.

Reports the macro average of the per-sequence ROUGE-L F1 scores.

Implementations

impl RougeLScore

pub fn new() -> RougeLScore

Creates a new ROUGE-L metric.

pub fn with_pad_token(self, index: usize) -> RougeLScore

Sets the pad token index. Tokens matching this value are stripped from the right of each sequence before scoring.

Trait Implementations

impl Clone for RougeLScore

fn clone(&self) -> RougeLScore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for RougeLScore

fn default() -> RougeLScore

Returns the “default value” for a type.

impl Metric for RougeLScore

type Input = RougeLInput

The input type of the metric.

fn update( &mut self, input: &RougeLInput, _metadata: &MetricMetadata, ) -> Result<SerializedEntry, TensorReadError>

Update the metric state and returns the current metric entry.

fn compute(&mut self) -> Result<SerializedEntry, TensorReadError>

Compute the final metric value.

fn clear(&mut self)

Clear the metric state.

fn name(&self) -> Arc<String>

The parameterized name of the metric.

fn attributes(&self) -> MetricAttributes

Attributes of the metric.

fn description(&self) -> Option<String>

A short description of the metric.

impl Numeric for RougeLScore

fn value(&self) -> Option<NumericEntry>

Returns the numeric value of the metric, or None if this metric has no meaningful value yet (e.g. it only accumulates state per batch and computes its value once all state has been accumulated).

fn running_value(&self) -> Option<NumericEntry>

Returns the current aggregated value of the metric over the global step, or None if this metric has no meaningful value yet (e.g. it only accumulates state per batch and computes its value once all state has been accumulated).

fn final_value(&self) -> NumericEntry

Returns the final, authoritative value of the metric for the epoch. Only meaningful after Metric::compute has been called.
