Struct SparseActivations 

Source 
pub struct SparseActivations<F: FeatureId> {
    pub features: Vec<(F, f32)>,
}
Expand description

Sparse representation of feature activations.

Only features with non-zero activation are stored, sorted by activation magnitude in descending order.

Generic over the feature identifier type F:

  • CltFeatureId for CLT features (layer + index, requires clt feature)
  • SaeFeatureId for SAE features (index only, requires sae feature)

Fields§

§features: Vec<(F, f32)>

Active features with their activation magnitudes, sorted descending.

Implementations§

Source§

Number of active features.

Source

pub const fn is_empty(&self) -> bool

Whether no features are active.
