Struct CosineAnnealingLrSchedulerConfig

pub struct CosineAnnealingLrSchedulerConfig { /* private fields */ }

The configuration for creating a Cosine Annealing learning rate scheduler with warm restarts.

This scheduler returns the learning rate initial_lr at the first step, then changes it by following a cosine function. After num_iters iterations, the learning rate is reset to initial_lr.

Implementations

impl CosineAnnealingLrSchedulerConfig

pub fn new( initial_lr: f64, num_iters: usize, ) -> CosineAnnealingLrSchedulerConfig

Create a new instance of the config.

impl CosineAnnealingLrSchedulerConfig

pub fn with_min_lr(self, min_lr: f64) -> CosineAnnealingLrSchedulerConfig

Set the default value for the field.

impl CosineAnnealingLrSchedulerConfig

pub fn init(&self) -> Result<CosineAnnealingLrScheduler, String>

Initializes a Cosine learning rate scheduler.

Errors

An error will be returned if any of the following conditions is true:

• initial_lr is out of range (0.0, 1.0]
• min_lr is out of range [0.0, initial_lr]
• num_iters is 0
