Modified NSGA-II for a Bi-Objective Job Sequencing Problem
Job Sequencing Multi-Objective Evolutionary Algorithm (MOEA) NSGA-II (Non-Dominated Sorting Genetic Algorithm-II) Tardiness Deterioration Cost
2013/1/28
This paper proposes a better modified version of a well-known Multi-Objective Evolutionary Algorithm (MOEA) known as Non-dominated Sorting Genetic Algorithm-II (NSGA-II). The proposed algorithm contai...
针对海量信息处理对传统的商业智能软件提出的挑战,设计并实现了一种基于并行机制的商务智能(BI)系统(BI-PaaS)。该系统搭建在中国移动大云基础设施之上, 以云计算的强大并行计算和分布式存储能力为支撑,将ETL、DM、OLAP、Report等各类BI能力并行化。实验结果表明,基于并行机制的BI-PaaS系统可以大大提高BI能力的数据处理性能,有效地支持电信运营的海量数据分析。
AN APPROXIMATION ALGORITHM FORWORD-REPLACEMENT USING A BI-GRAM LANGUAGE MODEL
word-replacement statistical machine translation NP-hard Hamiltonian Path Problem
2012/12/3
This paper presents an approximation algorithm for wordreplacement under a bi-gram language model. Words replacement is an key step in the decoding part of statistical machine translation. However, th...
A 3D Auto-Regressive Model for Bi-Directional Prediction
3D AR bi-directional prediction nonlinear least squares
2013/7/16
In this paper, a 3D auto-regressive (AR) model is proposed for bi-directional prediction. The prediction is composed of two 3D AR models, which are along the forward and backward directions, respectiv...
BI-STCM-ID系统的标识映射设计及性能分析
比特交织空时编码调制 迭代译码 标识映射 自适应标识
2007/11/1
重点研究了对比特交织空时编码及迭代译码系统(BI-STCM-ID)性能影响较大的标识映射方法，提出了给定区间最佳映射(DRO)的设计方法以及自适应标识映射集的思想.通过对各种映射方法特征参数及渐进BER性能限的分析，得出了瑞利衰落信道环境下决定BICM-ID以及BI-STCM-ID系统性能的关键参数，进而给出了标识映射设计的参考准则.
