Struct MetaStats 

pub struct MetaStats {
    pub meta_losses: Vec<f64>,
    pub task_losses: Vec<Vec<f64>>,
    pub iterations: usize,
}

Meta-learning statistics tracker.

Fields

meta_losses: Vec<f64>

Meta-training losses over time.

task_losses: Vec<Vec<f64>>

Task adaptation losses.

iterations: usize

Number of meta-iterations completed.

Implementations

impl MetaStats

pub fn new() -> Self

pub fn avg_meta_loss(&self, last_n: usize) -> f64

Get average meta-loss over last N steps.

pub fn is_improving(&self, window: usize) -> bool

Check if meta-training is improving (loss decreasing).
