4.pareto frontier是指一个pareto effciency 的状态集合 PE-LTR(pareto efficiency learning to rank): 假设有 K 个目标,每个目标都有对于可微的函数表达和 loss ; θ 表示模型的参数; Li(θ) 表示第 i 个目标的 loss , 则总体的 loss 为 L(θ)=∑iKLi(θ)∗wi 。单个优化一个目标是简单的,但是要...
We propose a new formulation that accounts for the importance of the parameter space and is thus more suitable for multiobjective design problems; instead of searching for the Paretoefficient frontier, we solicit the desired minimum performance thresholds on all objectives to define regions of ...
aSimilar to the 6 job instance, the Pareto efficient frontier was computed by searching for the minimum makespan, given 21 different speci-fied upper bounds on the peak load. 相似于6个工作事例, Pareto高效率的边境通过搜寻在最大负荷计算极小makespan给出21个不同指定的最高界面。[translate]...
Thus, our approach leads to the closest targets by means of a single-stage procedure, which is easier to handle than those based on algorithms aimed at identifying all the facets of the efficient frontier. 展开 关键词: data envelopment analysis (DEA) target setting minimum distance to the ...
In this paper we present an efficient and effective method of using surrogate approximations to explore the design space and capture the Pareto frontier during multiobjective optimization. The method employs design of experiments and metamodeling techniques (e.g., response surfaces and kriging models) ...
On the other hand, both the Return-on-output (ROO) and Quantity-control regulations are Pareto efficient that can keep the transit system operating along the Pareto-efficient frontier. Especially, Quantity-control regulation seems to be more attractive than ROO as there is no need for the firm...
We set up a Pareto-efficient tax problem and analyze the entire second-best Pareto-frontier, highlighting several non-standard results, such as the possibility of income re-ranking relative to the laissez-faire and gaps in the Pareto-frontier. ...
aThe boundary of this set--the utility possibilities frontier--is the set of utility levels associated with Pareto efficient allocations 这个集合界限 --公共可能性边境--是套公共水平与Pareto高效率的分派相关[translate]
The construction and analysis of Pareto-efficient frontier production functions by a new Data Envelopment Analysis method is presented in the context of new theoretical characterizations of the inherent structure and capabilities of such empirical production functions. Contrasts and connections with other dev...
Moreover, considering the needs of real-world e-commerce platforms, it would be more desirable if we can generalize the whole Pareto Frontier, so that the decision-makers can specify any preference of one objective over another based on their current business needs. Therefore, in this work, ...
