Expand description

Sensitivity metric for a model layer — higher score means more sensitive to quantization.

Fields§

§layer_name: String§gradient_norm: f64

Average gradient norm during training.

§weight_variance: f64

Variance of weight values.

§activation_range: f64

Activation range: max − min of activations.

§output_sensitivity: f64

How much output changes per unit weight change.

§is_embedding: bool

Embedding layers usually require higher precision.

§is_final_layer: bool

Final layers usually require higher precision.

Implementations§

Source §

impl LayerSensitivity

Source

pub fn sensitivity_score(&self) -> f64

Compute a composite sensitivity score for this layer.

Formula: gradient_norm * 0.4 + weight_variance * 0.3 + activation_range * 0.2 + output_sensitivity * 0.1

Bonuses: embeddings +1.0, final layer +0.5.
