Struct HebbianState 

pub struct HebbianState {
    pub activations: Vec<ActivationRecord>,
    pub coactivations: HashMap<(u32, u32), CoactivationPair>,
    pub fingerprints: Vec<ActivationFingerprint>,
}

In-memory Hebbian state, loaded from binary files.

Fields

activations: Vec<ActivationRecord>

coactivations: HashMap<(u32, u32), CoactivationPair>

fingerprints: Vec<ActivationFingerprint>

Implementations

impl HebbianState

pub fn load_or_init(output_dir: &Path, block_count: usize) -> Self

Load or initialize Hebbian state for a given block count.

pub fn record_activation(&mut self, results: &[(u32, f32)], query_hash: u64)

Record that a set of blocks were activated together by a query. This is the core Hebbian learning signal.

pub fn apply_drift(&mut self, headers: &[(f32, f32, f32)])

Apply Hebbian drift: co-activated blocks pull each other’s coordinates closer. Call this during rebuild or periodically.

pub fn effective_coords( &self, block_idx: usize, original: (f32, f32, f32), ) -> (f32, f32, f32)

Get effective coordinates for a block (original + Hebbian drift).

pub fn energy(&self, block_idx: usize) -> f32

Get the energy (heat) of a block. 1.0 = just activated, decays toward 0.

pub fn save(&self, output_dir: &Path) -> Result<(), String>

Save all Hebbian state to binary files.

pub fn stats(&self) -> HebbianStats

Get statistics about the Hebbian state.

pub fn latest_fingerprint(&self) -> Option<&ActivationFingerprint>

Get the latest activation fingerprint (for mirror neuron sharing).

pub fn hottest_blocks(&self, n: usize) -> Vec<(usize, f32)>

Get top-N most activated blocks.

pub fn strongest_pairs(&self, n: usize) -> Vec<&CoactivationPair>

Get top-N strongest co-activation pairs.
