Struct PowerSgdConfig 

#[non_exhaustive]
pub struct PowerSgdConfig {
    pub rank: usize,
    pub n_power_iter: usize,
    pub reuse_momentum: bool,
}

Configuration for PowerSGD low-rank gradient compression.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rank: usize

Target rank for the low-rank decomposition. Default: 4.

n_power_iter: usize

Number of power-iteration steps to improve the approximation. Default: 1.

reuse_momentum: bool

Reuse the left factor as momentum across rounds. Default: true.

Trait Implementations

impl Clone for PowerSgdConfig

fn clone(&self) -> PowerSgdConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PowerSgdConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PowerSgdConfig

fn default() -> Self

Returns the “default value” for a type.
