Implementations

impl MultiModalFeatureSelectorBuilder

pub fn new() -> Self

pub fn fusion_strategy(self, strategy: &str) -> Self

Fusion strategy: “early”, “late”, or “hybrid”.

pub fn modality_weights<I>(self, weights: I) -> Self

where I: IntoIterator<Item = (&'static str, f64)>,

Set weights for different modalities.

pub fn modality_k<I>(self, k_values: I) -> Self

where I: IntoIterator<Item = (&'static str, usize)>,

Set number of features to select per modality (for late fusion).

pub fn cross_modal_analysis(self, enable: bool) -> Self

Whether to perform cross-modal correlation analysis.

pub fn cross_modal_threshold(self, threshold: f64) -> Self

Threshold for cross-modal correlation significance.

pub fn normalize_modalities(self, normalize: bool) -> Self

Whether to normalize features within each modality.

pub fn handle_missing_modalities(self, handle: bool) -> Self

Whether to handle missing modalities gracefully.

pub fn min_modalities_required(self, min: usize) -> Self

Minimum number of modalities required for processing.

pub fn missing_strategy(self, strategy: &str) -> Self

Strategy for handling missing modalities: “ignore”, “impute”, or “error”.

pub fn k(self, k: usize) -> Self

Total number of features to select (for early/hybrid fusion).

pub fn score_threshold(self, threshold: f64) -> Self

Minimum score threshold for feature selection.

pub fn correlation_method(self, method: &str) -> Self

Correlation method: “pearson”, “spearman”, or “mutual_info”.

pub fn interaction_analysis(self, enable: bool) -> Self

Whether to analyze feature interactions across modalities.

pub fn max_interaction_order(self, order: usize) -> Self

Maximum order of interactions to consider (2 = pairwise, 3 = three-way, etc.).

pub fn build(self) -> MultiModalFeatureSelector<Untrained>

Builds the MultiModalFeatureSelector.
