Webthis paper, we propose a class of simple, ﬂexible algorithms, called LambdaRank, which avoids these difﬁculties by working with implicit cost functions. We de-scribe LambdaRank using neural network models, although the idea applies to any differentiable function class.

Websuch that the NLE ˚can be MMSE-optimal. Such local-optimality allows the use of the I-MMSE theorem to obtain the achievable rate of OAMP. We prove that this achievable rate is equal to the constrained capacity, which leads to the capacity-optimality of OAMP. The proof of capacity-optimality of OAMP in this paper can also be extended to the vector WebWe empirically show that LambdaRank finds a locally optimal solution for NDCG, MAP and MRR with a 99% confidence rate.
