Proposal, verification and comparison on infinitely many ZTFs leading to various nets for Zhang matrix inverse solving 张氏矩阵反解的无穷多个ztf的提出、验证和比较
Binbin Qiu, Yunong Zhang, Zhi Yang
Lately, Zhang et al have proposed the notion of infinitely many Z-type functions (ZTFs) leading to various Z-type neural nets (ZTNNs), and established a systematic approach (i.e., the general-form ZTNN, GFZTNN) for the real-time solution of a time-varying matrix inverse (also termed, Zhang matrix inverse, ZMI). Being a supplementary and in-depth research, this paper provides the theoretical result on the convergence performance of the GFZTNN model. Besides, such a GFZTNN model is generalized and exploited for computing the time-varying Drazin inverse (TVDI) instead of the usual constant one. Finally, computer simulations with two illustrative examples are performed to show the efficacy and advantage of two specific ZTNN models originating from the GFZTNN model for the realtime solution of ZMI and/or TVDI.
最近,Zhang等人提出了无限多个z型函数(ztf)导致各种z型神经网络(ZTNN)的概念,并建立了一种系统的方法(即一般形式的ZTNN, GFZTNN)来实时求解时变矩阵逆(也称为Zhang矩阵逆,ZMI)。作为补充和深入研究,本文给出了GFZTNN模型收敛性能的理论结果。此外,将该GFZTNN模型推广并应用于计算时变德拉津逆(TVDI),而不是通常的常数模型。最后,通过两个实例进行了计算机仿真,验证了源自GFZTNN模型的两种特定的ZTNN模型在实时求解ZMI和/或TVDI时的有效性和优越性。

Near future prediction of European population through Chebyshev-activation WASD neuronet 通过切比舍夫激活WASD神经网络对欧洲人口近未来的预测
Yunong Zhang, Jinjin Wang, Qingkai Zeng, H. Qiu, Hongzhou Tan
With the world population increasing rapidly, the conflicts between the population and limited resources have become more and more severe. Population growth is a root cause of many environmental and social problems. Therefore, it is of vital importance to make population predictions. However, predictions based on standard cohort-component method fails to consider all relevant impact factors and may neglect some important uncertainty factors. To overcome the inherent limitations, in this article, we present a Chebyshev-activation WASD neuronet approach for the population prediction. This neuronet method is applied to predicting European population, with numerous numerical experiments conducted as a research basis to guarantee the feasibility and validity of our approach. It is predicted with the most possibility that European population will decrease in the near future.
随着世界人口的迅速增长,人口与有限资源之间的矛盾日益严重。人口增长是许多环境和社会问题的根源。因此,人口预测是至关重要的。然而,基于标准队列成分法的预测没有考虑到所有相关的影响因素,可能会忽略一些重要的不确定性因素。为了克服固有的局限性,在本文中,我们提出了一种切比雪夫激活WASD神经元方法用于人口预测。将该神经网络方法应用于欧洲人口预测,并进行了大量的数值实验作为研究基础,以保证方法的可行性和有效性。据预测,欧洲人口极有可能在不久的将来减少。

Yunong Zhang, Ying Fang, Bolin Liao, Tianjian Qiao, Hongzhou Tan
In this paper, a discrete-time Zhang neural network (DTZNN) model, discretized from continuous-time Zhang neural network, is proposed and investigated for performing the online future minimization (OFM). In order to approximate more accurately the 1st-order derivative in computation and discretize more effectively the continuous-time Zhang neural network, a new Taylor-type numerical differentiation formula, together with the optimal sampling-gap rule, is presented and utilized to obtain the Taylor-type DTZNN model. For comparison, Euler-type DTZNN model and Newton iteration, with an interesting link being found, are also presented. Moreover, theoretical results of stability and convergence are presented, which show that the steady-state residual errors of the presented Taylor-type DTZNN model, Euler-type DTZNN model and Newton iteration have a pattern of 0(t3), 0(t2) and 0(t), respectively, with t denoting the sampling gap. Numerical experimental results further substantiate the effectiveness and advantages of the Taylor-type DTZNN model for solving the OFM problem.

Voice conversion using deep neural network in super-frame feature space 基于超帧特征空间的深度神经网络语音转换
Wei Ye, Yibiao Yu
This paper presents a voice conversion technique using deep neural networks (DNNs) to map the spectral envelopes of a source speaker to that of a target speaker. Short-time spectral envelopes are represented by the linear predication cepstrum coefficients (LPCC) parameters, and neighbor frames are gathered to form super-frames. Then the powerful mapping ability of DNN which has a five-layer architecture consisting of three restricted Boltzmann machines (RBMs) was exploited to derive the spectral conversion function. A comparative study of voice conversion using a DNN model and the conventional Gaussian mixture model (GMM) is conducted. Experimental results show the speaker identification rate of conversion speech achieves 97.5% which is 0.8% higher than the performance of GMM method, and the value of average cepstrum distortion is 0.87 which is 5.4% higher than the performance of GMM method. ABX and MOS evaluations indicate that the conversion performance is better than the traditional GMM method under the parallel corpora condition.

A new realization of MIMO multidimensional system for wireless sensor network 无线传感器网络中MIMO多维系统的新实现
Yang Xiong, Hua Cheng, Gengguo Cheng
Wireless sensor networks composed of a large number of sensor nodes have emerged recently as a candidate for a wide variety of applications. This paper explores the Rosser state-space model realization problem in regular rectangular wireless sensor networks by using elementary operation. The new elementary operation approach (EOA) proposed recently by the authors for the single-input and single-output (SISO) case will be extended to the multi-input and multi-output (MIMO) case. It is shown that, due to the structural properties of Roesser model, the n-D realization problem can be reduced as an elementary operation problem of a certain n-D polynomial matrix for an n-D transfer matrix represented by a right matrix fraction description (RFD). Then, a general constructive realization procedure will be presented, which can guarantee a regular realization and completely overcome the singularity problem in Galkowski's approach. Finally, an illustrative example will be given to show the details and the effectiveness of the proposed approach.

A dynamic approach for estimating service performance in the cloud 用于评估云中的服务性能的动态方法
X. Zhao, Bin Zhang, Changsheng Zhang, L. Wang
Accurately estimating the service performance under a given resource configuration is of great importance to the resource provision for services in cloud platforms. To achieve this, it is necessary to build service performance models, the accuracy of which, however, is usually significantly influenced by the scale of training data. In this paper, combining collaborative filtering recommendation (CFR) and artificial neural network (ANN), we present a dynamic service performance modeling approach, called CADM, to improve the accuracy of estimation. In CADM, both performance models based on CFR and ANN are trained at service deployment time and runtime, and the one with lower mean absolute error is chosen to estimate the performance. Moreover, a merit-based threshold is introduced to reduce training costs. The experimental results illustrate that CADM has higher accuracy on different scales of training data, and the merit-based threshold has a significant impact on the estimation accuracy as well as the modeling efficiency.
准确估计给定资源配置下的服务性能对云平台中服务的资源配置具有重要意义。为了实现这一点,有必要构建服务性能模型,然而,其准确性通常受到训练数据规模的显著影响。本文将协同过滤推荐(CFR)与人工神经网络(ANN)相结合,提出了一种动态服务性能建模方法——CADM,以提高服务性能估计的准确性。在CADM中,基于CFR和ANN的性能模型都在服务部署时和运行时进行训练,并选择平均绝对误差较小的模型进行性能估计。此外,还引入了基于绩效的门槛,以减少培训成本。实验结果表明,CADM在不同尺度的训练数据上都有较高的准确率,基于优点的阈值对估计精度和建模效率有显著影响。

Convex combination of quantized kernel least mean square algorithm 凸组合量化核最小均方算法
Yunfei Zheng, Shiyuan Wang, Yali Feng, Wenjie Zhang, Qingan Yang
In this paper, we propose an new kernel adaptive filter, namely convex combination of quantized kernel least mean square algorithm (CC-QKLMS). By applying the convex combination idea to QKLMS, the CC-QKLMS takes the kernel sizes as the combined variables, which can achieve a fast convergence rate and a low steady-state mean-square error (MSE). In addition, since the quantization method is incorporated in CC-QKLMS, a linear growing network structure is naturally avoided. Simulation results on channel equalization validate the better performance of the CC-QKLMS in terms of the convergence rate and steady-state MSE.
本文提出了一种新的核自适应滤波器,即凸组合量化核最小均方算法(CC-QKLMS)。将凸组合思想应用到QKLMS中,CC-QKLMS以核大小作为组合变量,具有较快的收敛速度和较低的稳态均方误差。此外,由于量化方法被纳入CC-QKLMS,自然避免了线性增长的网络结构。信道均衡的仿真结果验证了CC-QKLMS在收敛速率和稳态MSE方面具有更好的性能。

Simulation results on channel equalization validate the better performance of the CC-QKLMS in terms of the convergence rate and steady-state MSE.","PeriodicalId":265426,"journal":{"name":"2015 Sixth International Conference on Intelligent Control and Information Processing (ICICIP)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125206201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
