Struct TieredCurriculum 

pub struct TieredCurriculum { /* private fields */ }

Tiered curriculum for diagnostic verbosity levels

Designed for CITL training with four diagnostic tiers:

• Tier 1: JSON diagnostics + clippy (baseline)
• Tier 2: + verbose build output
• Tier 3: + RUSTC_LOG traces
• Tier 4: + full debug output

Tier advancement based on accuracy thresholds.

Example

use entrenar::train::{TieredCurriculum, CurriculumScheduler};

let mut curriculum = TieredCurriculum::new(vec![0.6, 0.7, 0.8], 3);

assert_eq!(curriculum.tier(), 1);

// Advance to tier 2 after achieving 60% accuracy for 3 epochs
for _ in 0..3 {
    curriculum.step(0, 0.65);
}
assert_eq!(curriculum.tier(), 2);

Implementations

impl TieredCurriculum

pub fn new(tier_thresholds: Vec<f32>, patience: usize) -> Self

Create new tiered curriculum

Arguments

• tier_thresholds - Accuracy thresholds for each tier advancement
• patience - Epochs at threshold before advancing

pub fn citl_default() -> Self

Create with default CITL thresholds

• Tier 1 -> 2: 60% accuracy
• Tier 2 -> 3: 70% accuracy
• Tier 3 -> 4: 80% accuracy

pub fn current_threshold(&self) -> Option<f32>

Get the threshold for current tier advancement
