    retrieved_lists: &[Vec<usize>],
    relevant_sets: &[HashSet<usize>],
) -> f64
Expand description

Calculate Mean Average Precision (MAP).

MAP considers precision at each relevant item position.

§Arguments

  • retrieved_lists - List of ranked result lists (one per query)
  • relevant_sets - List of relevant item sets (one per query)

§Returns

MAP in range [0.0, 1.0]. Higher is better.
