A Dynamically Adding Information Recommendation System based on Deep Neural Networks 基于深度神经网络的动态添加信息推荐系统
Yang Zhou
The recommendation system is a widely researched business tool that provides recommendations such as products or technologies that users are interested. The recommendation system learns user information by analyzing customer behavior and recommends products to meet customer needs. The existing mainstream recommendation systems still have room for improvement in terms of dynamically adding new users or new products to the system. The proposed method dynamically adds user and product information to the original recommendation system while recommending target content to new users or new products. While retaining the CIN and DNN structures, the networks associations are added to the before and after sequences. The input part of the add sequence is added to the previous sequence, the purpose is to dynamically update user and product information, adjust networks parameters based on sequence associations and learn high-order and low-order features of information. The results of comparative experiments show that our method could add new information dynamically with the low computing cost.

ImageDC: Image Data Cleaning Framework Based on Deep Learning ImageDC:基于深度学习的图像数据清理框架
Yun Zhang, Zongze Jin, Fan Liu, Weilin Zhu, Weimin Mu, Weiping Wang
Although user-generated image data increases more and more quickly on the current Internet, many image methods have attracted widespread attention from industry and academia. Recently, some image classification approaches using deep learning have demonstrated that they can potentially enhance the accuracy of the classification based on the high quality datasets. However, the existing methods only consider the accuracy of the classification and ignore the quality of the datasets. To address these issues, we propose a new image data cleaning framework using deep neural networks, named ImageDC, to improve the quality of the datasets. ImageDC not only uses cleaning with the minority class to remove the images of the rarely classes, but also adopts cleaning with the low recognition rate to remove the noisy data to enhance the recognition rate of the datasets. Experimental results conducted on a variety of datasets demonstrate that our model significantly outperforms the whole approaches.
虽然当前互联网上用户生成的图像数据增长越来越快,但许多图像方法也引起了业界和学术界的广泛关注。最近,一些使用深度学习的图像分类方法已经证明,它们可以潜在地提高基于高质量数据集的分类的准确性。然而,现有的方法只考虑了分类的准确性,而忽略了数据集的质量。为了解决这些问题,我们提出了一个新的图像数据清洗框架,使用深度神经网络,命名为ImageDC,以提高数据集的质量。ImageDC不仅采用少数类的清洗方法去除少数类的图像,而且采用低识别率的清洗方法去除噪声数据,以提高数据集的识别率。在各种数据集上进行的实验结果表明,我们的模型明显优于整个方法。

Xiaoyong Sun, Zhen Zuo, Shaojing Su, Xiaopeng Tan
In this paper, we propose and demonstrate a blind chromatic dispersion (CD) estimation method based on fractional Fourier transformation (FrFT). When FrFT acts on linear frequency modulated (LFM) signal with energy convergence, it is compared to fiber chromatic dispersion signal, and the best order can be obtained by scanning or search method. Through numerical simulations, reliable CD estimation is demonstrated for 28 GBaud PM-QPSK and PM-16QAM signals with a range of (-70,45) ps/nm. The average estimation error of CD estimation is 0.15% and 0.5% when the transmission distance over 100km~2000km standard single mode fiber (SSMF).

Yajuan Jia, Juanjuan Wang, Lisha Shang
The rapid development of urban rail transit in our country also puts forward further requirements for its braking system, so it is of great significance to carry out auxiliary design of its braking system and to carry out simulation calculation of its working characteristics. The running time between stations of metro vehicles is generally 2 ~ 4 min, which is in a state of frequent starting and braking. The traction load of metro vehicles is nonlinear, random and time-varying. Compared with other loads in the power grid, subway load has its particularity. ActiveX is used to analyze the traction and braking characteristics of subway trains. The traction load theory of subway trains is studied in detail, the parameters of load modeling are determined, the corresponding effective data are obtained, the corresponding data processing scheme is formulated, and the real-time simulation tool MATLAB is used to simulate the operation of subway trains. The braking energy distribution model can provide theoretical support for various urban rail transit braking energy recovery methods, and can also provide basis for selection of various braking energy recovery devices.

A multi-pedestrian cooperative navigation and positioning method based on UWB technology 一种基于超宽带技术的多行人协同导航定位方法
Shufang Zhang, Xianfei Pan, Hua Mu
Cooperative navigation which can improve the individual localization accuracy through utilizing the relative information among multiple individuals is a problem worthy of discussing. In the case of limited satellite signals, pedestrian navigation based on the micro inertial measurement unit can achieve autonomous and continuous navigation results, but during the inertial navigation calculation process, the navigation error of a single pedestrian is easy to diverge. Multi-pedestrian cooperative navigation is a navigation method that integrates and shares navigation information of multiple pedestrians. The relative distance between pedestrians can be measured by ultra-wide band technology and used to form a constraint relationship between multi-pedestrian navigation states. Then, the Kalman filter principle is used to establish a multi-pedestrian cooperative navigation system model in order to control the divergence of navigation errors, thereby improving overall navigation accuracy. The experimental results show that the overall navigation performance is effectively improved and the navigation accuracy of some pedestrians is significantly optimized when the multi-pedestrian cooperative navigation and positioning method is adopted.
协同导航利用多个个体之间的相对信息来提高个体的定位精度是一个值得探讨的问题。在卫星信号有限的情况下,基于微惯性测量单元的行人导航可以实现自主、连续的导航结果,但在惯性导航计算过程中,单个行人的导航误差容易发散。多行人协同导航是一种整合和共享多行人导航信息的导航方法。行人之间的相对距离可以通过超宽带技术测量,并用于形成多行人导航状态之间的约束关系。然后,利用卡尔曼滤波原理建立多行人协同导航系统模型,控制导航误差发散,从而提高整体导航精度。实验结果表明,采用多行人协同导航定位方法,整体导航性能得到有效提高,部分行人的导航精度得到显著优化。

Research on Anomaly Location Method for Nuclear Pump Vibration Monitoring Data Based on Correlation Coefficient 基于相关系数的核泵振动监测数据异常定位方法研究
Y. Wenmin, Hou Xiuqun, Li Yuanjiao, Jiang Qinglei, Bao Binbin
Nuclear power plants have accumulated a large amount of process monitoring data, but most of the data are not marked with specified patterns, which cannot be directly applied to the data-driven intelligent early warning and fault diagnosis. On-site alarm threshold can only locate a small number of abnormal vibration data, ignoring a large number of data that doesn't exceed alarm threshold but is obviously abnormal fluctuation of vibration phenomenon. To solve this problem, a method is proposed to locate abnormal vibration data based on correlation coefficient in this paper. This method takes the correlation coefficient of vibration data and corresponding time as the fluctuation index of measuring vibration data, and calculates the fluctuation threshold through historical data statistics, so as to locate abnormal vibration data. The vibration monitoring data of nuclear pump show that the proposed method can effectively detect the abnormal fluctuation of the data and locate the starting point of abnormal vibration.
核电厂积累了大量的过程监测数据,但大部分数据没有标记出特定的模式,无法直接应用于数据驱动的智能预警和故障诊断。现场报警阈值只能定位少部分异常振动数据,而忽略了大量未超过报警阈值但属于明显异常振动波动现象的数据。针对这一问题,本文提出了一种基于相关系数的异常振动数据定位方法。该方法以振动数据与对应时间的相关系数作为测量振动数据的波动指标,通过历史数据统计计算出波动阈值,从而定位异常振动数据。核泵振动监测数据表明,该方法能有效检测数据的异常波动,定位异常振动的起始点。

Design of a 5G Multi-band Mobile Phone Antenna Based on CRLH-TL 基于CRLH-TL的5G多波段手机天线设计
Peng Liu, W. Ren, Ruoqi Huang
Based on the principle of composite left and right hand transmission lines (CRLH- TL), a new type of multi-band hybrid multi-mode mobile phone antenna is designed. It is a combination of a monopole antenna and two Zero-order Resonator (ZOR) antennas. The antenna is printed on the PCB board of a typical smartphone with the size of 70 mm × 160 mm × 3.5 mm. Since the resonant frequency of ZOR antenna does not depend on the size characteristics, it will be helpful in the miniaturization of the antenna. Simulation results show that the center resonant frequencies locate at 1.04 GHz, 1.70 GHz, 2.52 GHz, 3.65 GHz, 4.26 GHz, and 4.9 GHz, covering the 4G LTE2300 (2305–2400 MHz), LTE2500 (2575–2635 MHz), DCS1800 (1710–1880 MHz), WLAN (2.4-2.485 GHz), and WiMAX (2.5-2.69 GHz, 3.3 -3.7 GHz) with good omnidirectional radiation characteristics and acceptable gain.

Detection of Spinal Fracture Lesions Based on Improved Faster-RCNN 基于改进Faster-RCNN的脊柱骨折病变检测
Gang Sha, Junsheng Wu, Bin Yu
Because of the problem that the complexity of spine CT images, the irregular shape of vertebral boundary, low contrast, noise and unevenness in images, meanwhile there are artificial deviations and low efficiencies in clinic, which needs doctors' prior knowledge and clinical experience to determine lesions location in CT images, so it can not meet the clinical realtime needs. In this paper, we use deep learning to process the CT images of spine, and to detect and locate lesion of (cervical fracture, cfracture), (thoracic fracture, tfracture), (lumbar fracture, lfracture) by the improved Faster-RCNN[1]. Through improving the RPN network in Faster-RCNN and changing the number of anchor, we choose appropriate length-width ratio to improve detection efficiency and accuracy. The experiment shows the results are more accurate, and mAP (mean average precision) of detection algorithm is 73.3%, detection rate is 0.03810 seconds per detection, which can basically meet the clinical real-time needs.

Wenhua Wu, Wei Cao, Ting Yan, Zhiguo Wang, Shu Wang
Most of the existing evidence dynamic reliability assessments are based on most principles, this method is not suitable for the case where there is only two evidences, and it is impossible to use this method to evaluate the reliability of two adjacent evidences in the time-domain evidence sequence. The concepts related to intuitionistic fuzzy sets and evidence theory is introduced and the relationship between intuitionistic fuzzy sets and BPAF are described. The research focuses on the dynamic reliability evaluation of evidence sequences. Combining the relationship between BPAF and intuitionistic fuzzy sets in evidence theory. Finally, a new method for evaluating the reliability of evidence is proposed, which realizes the evaluation of the reliability of each evidence source in the absence of prior knowledge.
现有的证据动态可靠性评估大多基于大多数原则,该方法不适用于只有两个证据的情况,也不可能用该方法评估时域证据序列中相邻的两个证据的可靠性。介绍了直觉模糊集和证据理论的相关概念,描述了直觉模糊集与BPAF之间的关系。研究重点是证据序列的动态可靠性评估。结合证据理论中BPAF与直觉模糊集的关系。最后,提出了一种新的证据可靠性评估方法,实现了在缺乏先验知识的情况下对各个证据源的可靠性进行评估。
