Struct ExponentialLrSchedulerConfig

pub struct ExponentialLrSchedulerConfig { /* private fields */ }

Available on crate feature std only.

The configuration for creating an exponential learning rate scheduler.

This scheduler returns the learning rate initial_lr at the first step, then multiplies it by a constant gamma at every iteration. At any iteration i (which starts from 0), the learning rate is given by initial_lr * gamma^i.

Implementations

impl ExponentialLrSchedulerConfig

pub fn new(initial_lr: LearningRate, gamma: f64) -> Self

Create a new instance of the config.

impl ExponentialLrSchedulerConfig

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

Initializes a exponential 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]
• gamma is out of range (0.0, 1.0]
