Struct PlasticityEngine 

pub struct PlasticityEngine {
    pub ewc: EwcPlusPlusBackend,
    pub btsp: Option<BtspBackend>,
    pub default_mode: PlasticityMode,
}

The unified plasticity engine.

Fields

ewc: EwcPlusPlusBackend

EWC++ is always present (canonical production backend)

btsp: Option<BtspBackend>

Optional BTSP for biological one-shot plasticity

default_mode: PlasticityMode

Default mode for new weight updates

Implementations

impl PlasticityEngine

pub fn new(lambda: f32) -> Self

pub fn with_btsp(self) -> Self

pub fn consolidate_with_phi( &mut self, weight_id: WeightId, weights: Vec<f32>, phi: f32, )

Set Φ-based protection weight for a consolidated pattern. phi > 1.0 protects the pattern more strongly from forgetting.

pub fn compute_delta( &mut self, weight_id: WeightId, current: &[f32], gradient: &[f32], lr: f32, mode: Option<PlasticityMode>, ) -> PlasticityDelta

Compute update delta for a weight, routing to appropriate backend.
