判断该用提示词、RAG 还是微调

只是写法示意，不是完整程序。

# ANS RAG 检索命中率 (Hit Rate @ K) 与平均倒数排名 (MRR) 计算器 (ans-rag-eval.py)
def evaluate_ans_retrieval(queries: list) -> dict:
    hits, rr_sum = 0, 0.0
    for q in queries:
        if q["gold_id"] in q["retrieved_ids"]:
            hits += 1
            rr_sum += 1.0 / (q["retrieved_ids"].index(q["gold_id"]) + 1)
    n = max(1, len(queries))
    return {"hit_rate": round(hits / n, 3), "mrr": round(rr_sum / n, 3)}
