Struct SemanticUtils 

Source 
pub struct SemanticUtils;
Expand description

Cosine similarity calculation utility. Used for vector-based semantic search when embedding API is available.

Implementations§

Source§

impl SemanticUtils

Source

pub fn cosine_similarity(a: &[f32], b: &[f32]) -> f32

Calculate cosine similarity between two embeddings.

§余弦相似度公式

cos(A, B) = (A · B) / (|A| × |B|)

取值范围：

  • 1.0 = 完全相同
  • 0.0 = 无关
  • -1.0 = 完全相反
