Global Stability Analysis of a Nonlinear Model of Internet Congestion Control with Delay
Nonlinear Model Stability Analysis
2015/6/19
In this paper we address global stability of a model for the TCP/AQM congestion control protocol. This model represents the dynamics of a single link and single source, and consists of a nonlinear dif...
Fast Algorithms for Resource Allocation in Wireless Cellular Networks
Wireless Cellular Networks Allocation
2015/6/19
We consider a scheduled orthogonal frequency division multiplexed (OFDM) wireless cellular network where the channels from the base-station to the n mobile users undergo flat fading. Spectral resource...
Optimal Control of Distributed Markov Decision Processes with Network Delays
Network Delays Decision Processes
2015/6/19
We consider the problem of finding an optimal feedback controller for a network of interconnected subsystems, each of which is a Markov decision process. Each subsystem is coupled to its neighbors via...
The Web browser interaction model popularized by NCSA Mosaic in 1993 contributed to the exponential growth of the Internet and has remained largely unchanged since then. However, even with multiple wi...

Social Networking PEDAGOGICAL-EDUCATIONAL Community of Learners
2015/5/26
The educational role of the worldwide web has been cast in a new light by the emergence of so-called ‘web 2.0’ technologies and, in particular, ‘social software’ where users are connected to and colla...
THE EXCHANGE OF SOCIAL SUPPORT VIA SOCIAL NETWORKS OF MATERNAL CAREGIVERS FOR CHILDREN WITH AUTISM SPECTRUM DISORDERS
special needs children with special needs autism
2015/5/26
The role of social support in the lives of the 16.8 million caregivers for children with special needs in the U.S. is not adequately understood. Many studies have explored seeking health information o...

针对多用户多输入单输出(MISO,multiple-input single-output)干扰信道中保密信息泄露问题,提出了理想信道状态信息(CSI,channel state information)下的安全协同波束成形(SCB,secure coordinated beamforming)方案和非理想CSI下的顽健安全协同波束成形(RSCB,robust secure coordinated...
提出了一种基于健壮多元概率校准模型的异常检测方法。该方法使用基于多元t分布的隐变量概率模型建立流量矩阵的常态模型,通过比较样本与常态模型之间的马氏距离进行流量异常检测。理论分析和实验表明该方法的健壮性较好,应用场景宽泛,既可以处理完整数据也可以处理数据缺失的情况,对干扰抵抗力较强,并且对模型参数的敏感性较低,性能稳定。
基于主体行为的多方安全协议会话识别方法

2015/12/21
针对分布在多个相关流中的多方安全协议会话问题,提出了多方安全协议会话的3个启发式的主体行为特征——邻接主机行为、主体角色行为以及主机消息行为,给出了主体行为特征检测原理,提出了多方安全协议会话识别方法。针对3个典型的多方安全协议,分别在3种会话运行场景下进行实验,结果表明该方法识别率在90%以上,误报率和漏报率在6%以下,能够有效地识别协议会话。

深度信念网络 网络深度 无监督学习 数字识别
2015/5/19
针对DBN网络隐含层层数难以选择的问题，首先从数学生物学角度分析了随机初始化的梯度下降法导致网络训练失败的原因，并进行验证，证明了RBM重构误差与网络能量的正相关定理;然后根据隐含层和误差的关系，提出一种基于重构误差的网络深度判断方法，在训练过程中自组织地训练网络，使其能够以一种接近人类处理问题的方式解决AI问题。手写数字识别的实验表明，该方法能够有效提高运算效率，降低运算成本。

直觉模糊集 核匹配追踪 集成学习 目标识别
2015/12/21
针对现有直觉模糊核匹配追踪算法采用部分样本进行训练和停机策略而导致学习机泛化能力下降的缺陷,结合集成学习的思想,提出了一种基于直觉模糊核匹配追踪集成的目标识别方法。该算法通过采用样本扰动和参数扰动的二重扰动策略产生子学习机,并利用多数投票法对其识别结果进行融合,从而提高了集成学习机的分类精度和泛化性能。实验结果表明,与传统方法相比,该方法可获得更优的识别效果,有效提高了识别精度,并能避免采样学习带...
