基于卷积神经网络的模式分类器     

李葆青 《大连大学学报》2003,24(2):19-23

研究了使用卷积神经网络((Convolutional Neural Networks,CNNS)构造模式分类器,并用于文本/图像分割和文本检测的可能性.CNNs可以避免显式(直接)特征取样.更为重要的是,CNNs能直接运作于灰度图像,使其应用变得直截了当.对诸如卷积核尺度、网络收敛速度等具体算法实现问题进行了讨论,并给出CNNs在汉字文本/图像分割和文本检测方面的各种实验结果.  相似文献   

EXPLICIT SOLUTIONS OF THE OPTIMUM WEIGHTS OF LAYERED NEURAL NETWORKS     

尤肖虎 《东南大学学报》1992,(1)

It is shown in this paper that if the hidden layer units take a sinusoidalactivation function,the optimum weights of the three-layer feedforward neural networkcan be explicitly solved by relating the layered neural network with a truncated Fourier se-ries expansion.Based on this result,two approaches are presented of which one is suited tothe case that the detailed statistical information is available or can be easily estimated.An-other is of data-adaptive type,which can be treated as a solution of standardleast-squares.The later is best suited to realtime processing and slowly time-varying ap-plications since it can be straightforwardly implemented by the traditional LMS or RLSadaptive algorithms.It is also shown that for both the approaches,the resulting networksown an ability of forming arbitrary mappings.By using the present approaches,theconventional training procedure,which is usually very time-consuming,can be avoided.  相似文献

连续时间生灭过程有限家庭树估计通信网络信息的传播速度     

马驰  王汉兴 《上海大学学报(英文版)》2007,11(3):237-240

A finite random graph generated by continuous time birth and death processes with exponentially distributed waiting times was investigated, which is similar to a communication network in daily life. The vertices are the living particles, and directed edges go from mothers to daughters. The size of the communication network was studied. Furthermore, the probability of successfully connecting senders with receivers and the transmitting speed of information were obtained.  相似文献   

On service differentiation in mobile Ad Hoc networks     

张顺亮  叶澄清 《Journal of Zhejiang University. Science. B》2004,(9)

A network model is proposed to support service differentiation for mobile Ad Hoc networks by combining a fully distributed admission control approach and the DIFS based differentiation mechanism of IEEE802.11. It can provide different kinds of QoS (Quality of Service) for various applications. Admission controllers determine a committed bandwidth based on the reserved bandwidth of flows and the source utilization of networks. Packets are marked when entering into networks by markers according to the committed rate. By the mark in the packet header, intermediate nodes handle the received packets in different manners to provide applications with the QoS corresponding to the pre-negotiated profile. Extensive simulation experiments showed that the proposed mechanism can provide QoS guarantee to assured service traffic and increase the channel utilization of networks.  相似文献
