Struct SHAPValues 

pub struct SHAPValues { /* private fields */ }

SHAP Values kernel.

Computes SHAP (SHapley Additive exPlanations) values for model predictions. Uses Kernel SHAP approximation which is model-agnostic and works with any prediction function.

SHAP values satisfy:

• Local accuracy: f(x) = base_value + sum(shap_values)
• Missingness: Missing features have 0 contribution
• Consistency: If a feature’s contribution increases, its SHAP value increases

Implementations

impl SHAPValues

pub fn new() -> Self

Create a new SHAP Values kernel.

pub fn explain<F>( instance: &[f64], background: &DataMatrix, predict_fn: F, config: &SHAPConfig, ) -> SHAPExplanation

where F: Fn(&[f64]) -> f64,

Compute SHAP values for a single instance.

Arguments

• instance - The instance to explain
• background - Background dataset for baseline
• predict_fn - Model prediction function
• config - SHAP configuration

pub fn explain_batch<F>( instances: &DataMatrix, background: &DataMatrix, predict_fn: F, config: &SHAPConfig, feature_names: Option<Vec<String>>, ) -> SHAPBatchResult

where F: Fn(&[f64]) -> f64,

Explain multiple instances.
