Struct OnlineLearnerStats 

pub struct OnlineLearnerStats {
    pub total_updates: u64,
    pub correct_predictions: u64,
    pub total_predictions: u64,
    pub avg_loss: f64,
    pub weight_norm: f64,
}

Running statistics tracked by OnlineLearner across all updates and predictions.

Fields

total_updates: u64

Total number of update() calls performed.

correct_predictions: u64

Number of predict_class() calls that returned the correct label.

total_predictions: u64

Total number of predict_class() calls.

avg_loss: f64

Running average of per-update losses.

weight_norm: f64

L2 norm of the weight vector at the time stats() was called.

Trait Implementations

impl Clone for OnlineLearnerStats

fn clone(&self) -> OnlineLearnerStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OnlineLearnerStats

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

Formats the value using the given formatter.

impl Default for OnlineLearnerStats

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for OnlineLearnerStats

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