Struct EarlyStopping 

pub struct EarlyStopping { /* private fields */ }

Early stopping callback to halt training when loss plateaus

Monitors a metric and stops training if no improvement is seen for patience epochs.

Example

use entrenar::train::callback::EarlyStopping;

// Stop if no improvement for 5 epochs, min improvement 0.001
let early_stop = EarlyStopping::new(5, 0.001);

Implementations

impl EarlyStopping

pub fn new(patience: usize, min_delta: f32) -> Self

Create new early stopping callback

pub fn with_restore_best(self) -> Self

Configure to restore best weights on stop

pub fn monitor_validation(self) -> Self

Configure to monitor validation loss (requires validation data)

When enabled, early stopping will only consider validation loss. If validation loss is not available, training loss is used as fallback.

pub fn reset(&mut self)

Reset internal state
