Two metrics to evaluate search algorithms
WebJun 12, 2014 · 1. Normalized discounted cumulative gain is one of the standard method of evaluating ranking algorithms. You will need to provide a score to each of the recommendations that you give. If your algorithm assigns a low (better) rank to a high scoring entity, your NDCG score will be higher, and vice versa. The score can depend on … WebJul 14, 2024 · Therefore we need metrics such as Mean Reciprocal Rank, Mean Average Precision (MAP) and nDCG that allows us to evaluate the quality of the keywords generated based on their Ranks as well. Let’s ...
