Enum FusionStrategy 

Source 
pub enum FusionStrategy {
    ScoreSum,
    ScoreMax,
    WeightedSum {
        text_w: f64,
        image_w: f64,

Expand description

How scores from different modalities are combined into a single fused score.

Variants§

§

ScoreSum

Sum all per-modality scores for the same result_id.

§

ScoreMax

Take the maximum per-modality score for the same result_id.

§

WeightedSum

Weighted sum: each modality’s score is multiplied by its weight before summing.

Fields

§text_w: f64

Weight applied to the Text modality score.

§image_w: f64

Weight applied to the Image modality score.

§audio_w: f64

Weight applied to the Audio modality score.

§code_w: f64

Weight applied to the Code modality score.

§struct_w: f64

Weight applied to the Structured modality score.

§

RankFusion

Reciprocal rank fusion: fused_score = Σ 1 / (rank + 60) across modalities.

Rank is 0-based within each modality’s result list (best rank = 0).
