Struct ConstantLR 

pub struct ConstantLR { /* private fields */ }

Available on crate feature alloc only.

Always returns the same learning rate.

This is the simplest scheduler and reproduces the behaviour of a plain fixed-rate ensemble. It exists so that code paths expecting a dyn LRScheduler can use a constant rate without special-casing.

Example

use irithyll::ensemble::lr_schedule::{LRScheduler, ConstantLR};

let mut sched = ConstantLR::new(0.05);
assert!(crate::math::abs((sched.learning_rate(0, 1.0) - 0.05)) < f64::EPSILON);
assert!(crate::math::abs((sched.learning_rate(1000, 0.1) - 0.05)) < f64::EPSILON);

Implementations

impl ConstantLR

pub fn new(lr: f64) -> Self

Create a constant-rate scheduler.

Arguments

• lr – The learning rate returned on every call.
