Struct ContextField 

pub struct ContextField { /* private fields */ }

The Context Field: computes Phi for a set of items given a task context.

Implementations

impl ContextField

pub fn new() -> Self

pub fn with_weights(weights: FieldWeights) -> Self

pub fn compute_phi(&self, signals: &FieldSignals) -> f64

Compute the unified potential Phi(i,t) for a context item.

All input signals should be normalized to [0, 1] before calling. The cost and redundancy terms are subtracted (penalty).

pub fn select_view(&self, costs: &ViewCosts, temperature: f64) -> ViewKind

Select the best view for an item given the temperature (budget pressure).

Uses Boltzmann-weighted view selection: P(view_v | item_i, T) = exp(-C(v) / T) / Z(i, T)

At low temperature (relaxed budget), denser views are preferred. At high temperature (tight budget), sparser views are preferred.

pub fn compute_batch( &self, items: &[(ContextItemId, FieldSignals, ViewCosts)], budget: TokenBudget, ) -> HashMap<ContextItemId, FieldPotential>

Compute potentials for a batch of items.

Trait Implementations

impl Default for ContextField

fn default() -> Self

Returns the “default value” for a type.
