Struct DiversityMonitor 

pub struct DiversityMonitor { /* private fields */ }

Monitors diversity of generated synthetic samples over time.

Tracks rolling statistics to detect trends like mode collapse or decreasing diversity during generation.

Example

use aprender::synthetic::{DiversityMonitor, DiversityScore};

let mut monitor = DiversityMonitor::new(5);

monitor.record(DiversityScore::new(0.5, 0.3, 0.7));
monitor.record(DiversityScore::new(0.4, 0.2, 0.6));

assert_eq!(monitor.sample_count(), 2);
assert!(monitor.mean_diversity() > 0.0);

Implementations

impl DiversityMonitor

pub fn new(window_size: usize) -> Self

Create a new diversity monitor.

Arguments

• window_size - Number of recent scores to track

pub fn with_collapse_threshold(self, threshold: f32) -> Self

Set the collapse detection threshold.

pub fn record(&mut self, score: DiversityScore)

Record a new diversity score.

pub fn sample_count(&self) -> usize

Get the number of samples in the window.

pub fn total_samples(&self) -> usize

Get total samples processed.

pub fn latest(&self) -> Option<DiversityScore>

Get the most recent diversity score.

pub fn mean_diversity(&self) -> f32

Get mean diversity over the window.

pub fn min_diversity(&self) -> f32

Get minimum diversity in the window.

pub fn max_diversity(&self) -> f32

Get maximum diversity in the window.

pub fn is_collapsing(&self) -> bool

Check if current diversity indicates collapse.

pub fn is_trending_down(&self) -> bool

Check if diversity is trending downward.

Compares first half of window to second half.

pub fn variance(&self) -> f32

Get diversity variance in the window.

pub fn reset(&mut self)

Clear all recorded scores.

pub fn compute_from_distances(distances: &[f32]) -> DiversityScore

Compute diversity score from pairwise distances.

Arguments

• distances - Pairwise distances between samples

Returns

Computed DiversityScore from the distances.
