What is listwise ranking?
Listwise ranking: A learning-to-rank approach that defines the loss over a whole ordered list, aligning training more closely with list-based metrics such as NDCG. It is more complex, since sorting is not differentiable.
Listwise ranking: an example
Optimise a smooth surrogate of NDCG computed over all 20 results for a query.
