Expand description

Cumulative statistics for an online learning session.

Fields§

§n_updates: usize

Total number of update calls.

§n_mistakes: usize

Total number of incorrect predictions (classification only).

§cumulative_loss: f64

Sum of per-sample losses.

§mean_loss: f64

Running mean loss: cumulative_loss / n_updates.

§last_weight_norm: f64

||w|| after the most recent update.

Implementations§

Source §

impl OnlineStats

pub fn mistake_rate(&self) -> f64

Fraction of updates that resulted in a mistake (classification).

Returns 0.0 when no updates have been performed.

Source

pub fn update(&mut self, result: &OnlineUpdateResult)

Incorporate the result of one update step into running statistics.
