Struct LotteryTicketConfig 

pub struct LotteryTicketConfig {
    pub target_sparsity: f32,
    pub pruning_rounds: usize,
    pub rewind_strategy: RewindStrategy,
    pub prune_rate_per_round: f32,
    pub global_pruning: bool,
}

Configuration for Lottery Ticket pruning.

Fields

target_sparsity: f32

Target sparsity (fraction of weights to prune, 0.0-1.0).

pruning_rounds: usize

Number of iterative pruning rounds. Each round prunes a fraction, accumulating to target_sparsity.

rewind_strategy: RewindStrategy

Strategy for rewinding weights after each pruning round.

prune_rate_per_round: f32

Pruning rate per round (computed from target_sparsity and rounds). p_per_round = 1 - (1 - target_sparsity)^(1/rounds)

global_pruning: bool

Whether to use global pruning (across all layers) or per-layer.

Implementations

impl LotteryTicketConfig

pub fn new(target_sparsity: f32, pruning_rounds: usize) -> Self

Create a new configuration.

Arguments

• target_sparsity - Final sparsity (0.0-1.0), e.g., 0.9 = 90% pruned
• pruning_rounds - Number of iterative pruning rounds

pub fn with_rewind_strategy(self, strategy: RewindStrategy) -> Self

Set the rewind strategy.

pub fn with_global_pruning(self, global: bool) -> Self

Enable or disable global pruning.

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

Performs copy-assignment from source.

impl Debug for LotteryTicketConfig

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

Formats the value using the given formatter.

impl Default for LotteryTicketConfig

fn default() -> Self

Returns the “default value” for a type.
