Struct CyclicalScheduler 

pub struct CyclicalScheduler { /* private fields */ }

Cyclical learning rates (CLR) — oscillates between min_lr and max_lr.

Uses triangular policy: linear up then linear down, period = 2 * step_size.

Implementations

impl CyclicalScheduler

pub fn new( min_lr: f64, max_lr: f64, step_size: usize, ) -> Result<Self, SchedulerError>

Create a new cyclical learning rate scheduler.

Errors

Returns SchedulerError::InvalidConfig if any parameter is invalid.

Trait Implementations

impl LrSchedulerV2 for CyclicalScheduler

fn step(&mut self) -> f64

Advance one step and return the new learning rate.

fn current_lr(&self) -> f64

Return the current learning rate without advancing.

fn reset(&mut self)

Reset the scheduler to its initial state.

fn steps_taken(&self) -> usize

Total number of steps taken.

fn completed_cycle(&self) -> bool

Whether the scheduler has completed a cycle (if applicable).
