Struct GatingAnalysis 

Source 
pub struct GatingAnalysis {
    pub gate_values: Vec<Array1<f32>>,
    pub avg_gate: Array1<f32>,
    pub dead_gates: Vec<usize>,
    pub saturated_gates: Vec<usize>,
    pub gate_entropy: f32,
}
Expand description

Analysis of gating patterns in gated models (RWKV, Mamba, etc.).

Fields§

§gate_values: Vec<Array1<f32>>

All captured gate activation vectors (one per step)

§avg_gate: Array1<f32>

Average gate value per unit, across all steps

§dead_gates: Vec<usize>

Indices of “dead” gates: average value below threshold

§saturated_gates: Vec<usize>

Indices of “saturated” gates: average value above 1 - threshold

§gate_entropy: f32

Shannon entropy of the average gate distribution (treating avg_gate as unnormalised probs)

Implementations§

Source§

impl GatingAnalysis

Source

pub fn from_activations( gate_values: Vec<Array1<f32>>, threshold: f32, ) -> ModelResult<Self>

Analyse the given gate activations.

§Parameters
  • gate_values — one Array1<f32> per time-step; all must have the same length
  • threshold — gates with avg < threshold are “dead”; avg > 1 - threshold are “saturated”
Source

pub fn effective_capacity(&self) -> f32

Fraction of gates that are neither dead nor saturated (effective gates).
