Struct ParameterGroup 

pub struct ParameterGroup {
    pub name: String,
    pub params: Vec<f64>,
    pub grad: Vec<f64>,
}

A named group of parameters together with their current gradients.

Both params and grad must have equal length when passed to AdaptiveOptimizer::step_group.

Fields

name: String

Unique identifier used as the key in the optimizer state map.

params: Vec<f64>

Current parameter values (updated in-place by the optimizer step).

grad: Vec<f64>

Gradient of the loss with respect to each parameter.

Implementations

impl ParameterGroup

pub fn new(name: impl Into<String>, params: Vec<f64>) -> Self

Create a new parameter group with all-zero gradients.

pub fn with_grad( name: impl Into<String>, params: Vec<f64>, grad: Vec<f64>, ) -> Self

Create a parameter group with explicit gradients.
