Web Service Quality Prediction Method Based on Recurrent Neural Network 基于递归神经网络的Web服务质量预测方法
X. Ye, Yanmei Wang, Zhichun Jia
For web services, QoS (Quality of Service, quality of service) is an important indicator for judging whether a web service is efficient. How to better predict the QoS value of the service to make appropriate service recommendations is the entire recommendation system and Issues that are being discussed in the service forecasting academia. At the same time, the timeliness and time relevance of QoS values are also affecting the prediction accuracy of Web services. A large amount of QoS data has potentially time-related attributes. This provides a new inspiration and thinking for service forecasting. Add the time characteristics of the data to the learning of the predictive model. Inspired by these factors, this paper proposes a deep neural network combination model that is sensitive to the time characteristics of QoS. At the same time, based on the final experimental results, the model proposed in this paper has obvious effects on the prediction of QoS values with time attributes.
对于web服务来说,QoS (Quality of Service,服务质量)是判断web服务是否高效的重要指标。如何更好地预测服务的QoS值,做出合适的服务推荐,是整个推荐系统和服务预测学术界正在讨论的问题。同时,QoS值的时效性和时间相关性也影响着Web服务的预测精度。大量的QoS数据具有潜在的时间相关属性。这为服务预测提供了新的启示和思路。将数据的时间特征加入到预测模型的学习中。受这些因素的启发,本文提出了一种对QoS时间特性敏感的深度神经网络组合模型。同时,根据最终的实验结果,本文提出的模型对具有时间属性的QoS值的预测效果明显。

Motion Detection and Object Detection: Yolo (You Only Look Once) 运动检测和目标检测:Yolo(你只看一次)
Zoubaydat Dahirou, Mao Zheng
Recently, the field of artificial intelligence has seen many advances thanks to deep learning and image processing. It is now possible to recognize images or even find objects inside an image with a standard GPU. Image processing is a recent science that aims to provide specialists from different areas, as to the general public, tools for manipulating these digital data from the real world. The detection of moving objects is a crucial step for systems based on image processing. The movements detected by the classic algorithms are not necessarily interesting for a thorough information search, and the need to distinguish the coherent movements of parasitic movements exists in most cases. In this paper we are going to use a simply webcam and YOLO algorithm for this implementation. The YOLOv3 (Version 3) model makes predictions with a single network evaluation, making this method extremely fast, running in real time with a capable GPU. From there we'll use OpenCV, Python, and deep learning to apply the YOLOv3 object to images and apply YOLOv3 to video streams.
最近,由于深度学习和图像处理,人工智能领域取得了许多进展。现在,使用标准GPU可以识别图像,甚至可以在图像中找到对象。图像处理是一门最新的科学,旨在为来自不同领域的专家提供工具,以操纵来自现实世界的这些数字数据。运动目标的检测是基于图像处理的系统的关键步骤。经典算法检测到的运动对于彻底的信息搜索来说不一定是有趣的,并且在大多数情况下需要区分寄生运动的相干运动。在本文中,我们将使用一个简单的网络摄像头和YOLO算法来实现这一目标。YOLOv3(版本3)模型通过单个网络评估进行预测,使该方法非常快,可以使用功能强大的GPU实时运行。从那里我们将使用OpenCV, Python和深度学习将YOLOv3对象应用于图像并将YOLOv3应用于视频流。

A Research on the Perception of Authenticity of Self-service Tourists Based on the Background of Smart Tourism 基于智慧旅游背景的自助游游客真实性感知研究
Na Gong, Haiyan Fu, Chi Gong
In recent years, the promotion of smart tourism has not only improved the level of information technology in tourist destinations, but also brought various conveniences to self-service tourists to a certain extent. However, the improvement of self-service tourists' satisfaction with the tourist destination experience has not been obvious. This article analyzes the influencing factors between self-service tourists' satisfaction with the authenticity of tourist destinations and the data information of smart tourism platforms from the perspective of tourist perception in the development of big data modernization. It is found that first, the incomplete information on the smart tourism platform reduces the authenticity of experience of self-service tourists; second, the lack of innovation in smart tourism information platforms affects the authenticity of tourist destinations; last, there is a conflict between the limitations of cultural resources and the perception of the perception of authenticity, and so on. The satisfaction of college students majoring in tourism from the place of origin and the local perception provides suggestions for the development of smart tourism, and is expected to play a corresponding guiding role in the development of tourist destinations. Therefore, it is proposed to provide sustainable and thorough suggestions for the development of smart tourism by utilizing the perception of satisfaction of tourism major students and residents from the local region, which can be expected that it can play a corresponding guiding role for the development of tourism destinations.
近年来,智慧旅游的推广,不仅提高了旅游目的地的信息化水平,也在一定程度上给自助游游客带来了各种便利。然而,自助游游客对旅游目的地体验满意度的提升并不明显。本文从大数据现代化发展中游客感知的角度,分析了自助游游客对旅游目的地真实性满意度与智慧旅游平台数据信息之间的影响因素。研究发现,一是智慧旅游平台上信息的不完整降低了自助游游客体验的真实性;二是智慧旅游信息平台缺乏创新,影响旅游目的地的真实性;最后,文化资源的有限性与对真实性的感知之间存在冲突,等等。旅游专业大学生对原籍地的满意度和对当地的感知为智慧旅游的发展提供了建议,并有望对旅游目的地的发展起到相应的指导作用。因此,本文提出利用旅游专业学生和当地居民的满意度感知,为智慧旅游的发展提供可持续、深入的建议,期望能够对旅游目的地的发展起到相应的指导作用。

Research on ShadowsocksR Traffic Identification Based on DART Algorithm 基于DART算法的ShadowsocksR流量识别研究
Qingbing Ji, Xiaoyan Deng, Lulin Ni
Shadowsocks (SS) is a new popular anonymous communication software in recent years. The traffic generated by SS is very difficult to identify. There is also an enhanced version of SS, called ShadowsocksR(SSR), which can disguise SS traffic as traditional protocol traffic, such as HTTP traffic, TLS traffic, etc. This makes the identification of SS traffic more difficult. In reference [16], an identification method of HTTP camouflaging traffic of SS is proposed for the first time. Here, a new identification method is proposed based on dart algorithm. Compared with reference [16], this method has more types and wider range of SSR obfuscated traffic, and has better identification effect for recent SSR obfuscated traffic, with the accuracy, the recall and the precision are all above 98.5%.

Lei Shao, Heyong Yuan, Xinfeng Wang, Wengang Liu, Qiao Zhang
Aiming at the problem of large deformation and soft fracture of soft rock in deep roadway, through theoretical analysis of deformation and failure characteristics of surrounding rock of deep roadway, the space-time evolution law of deformation and failure of surrounding rock of deep soft rock roadway is obtained by FLAC3D software simulation. The results show that: The deformation of surrounding rock in deep soft rock roadway is characterized by roof subsidence, two sides moving inward and floor bulging. Under the action of high stress, the deformation of surrounding rock of soft rock roadway has a certain timeliness. The deformation and failure of surrounding rock of roadway is a changing process with time. The damage degree of roof, floor and two sides of roadway increases with time, and finally tends to a stable state. The deformation presents a distribution law that the de-formation of floor is larger than that of roof and convergence of two sides.
针对深部巷道软岩大变形和软破裂问题,通过对深部巷道围岩变形破坏特征的理论分析,利用FLAC3D软件模拟得到深部软岩巷道围岩变形破坏的时空演化规律。结果表明:深部软岩巷道围岩变形表现为顶板沉陷、两边向内移动和底板胀形;在高应力作用下,软岩巷道围岩变形具有一定的时效性。巷道围岩的变形破坏是一个随时间变化的过程。巷道顶板、底板和巷道两侧的破坏程度随着时间的增加而增加,并最终趋于稳定。变形呈现出底板变形大于顶板变形且两侧收敛的分布规律。
