Struct EvaluationResult 

pub struct EvaluationResult {
    pub loss: f32,
    pub perplexity: f32,
    pub accuracy: f64,
    pub num_batches: usize,
    pub total_tokens: usize,
}

Result of evaluating a model on held-out sequences.

Fields

loss: f32

Average cross-entropy loss across all batches.

perplexity: f32

Perplexity = exp(average_loss).

accuracy: f64

Fraction of tokens where argmax(logits) == target (next-token accuracy).

num_batches: usize

Number of batches evaluated.

total_tokens: usize

Total number of (unmasked) tokens evaluated.
