An approach to Privacy on Recommended Systems 推荐系统的隐私保护方法
A. Luma, Blerton Abazi, Azir Aliu
Recommended systems are very popular nowadays. They are used online to help a user get the desired product quickly. Recommended Systems are found on almost every website, especially big companies such as Facebook, eBay, Amazon, NetFlix, and others. In specific cases, these systems help the user find a book, movie, article, product of his or her preference, and are also used on social networks to meet friends who share similar interests in different fields. These companies use referral systems because they bring amazing benefits in a very fast time. To generate more accurate recommendations, recommended systems are based on the user's personal information, eg: different ratings, history observation, personal profiles, etc. Use of these systems is very necessary but the way this information is received, and the privacy of this information is almost constantly ignored. Many users are unaware of how their information is received and how it is used. This paper will discuss how recommended systems work in different online companies and how safe they are to use without compromising their privacy. Given the widespread use of these systems, an important issue has arisen regarding user privacy and security. Collecting personal information from recommended systems increases the risk of unwanted exposure to that information. As a result of this paper, the reader will be aware of the functioning of Recommended systems, the way they receive and use their information, and will also discuss privacy protection techniques against Recommended systems.
推荐系统现在非常流行。它们在网上被用来帮助用户快速获得想要的产品。推荐系统几乎可以在每个网站上找到,尤其是像Facebook、eBay、Amazon、NetFlix等大公司。在特定情况下,这些系统可以帮助用户找到他或她喜欢的书籍、电影、文章、产品,也可以在社交网络上与在不同领域有相似兴趣的朋友见面。这些公司使用推荐系统是因为它们能在很短的时间内带来惊人的好处。为了产生更准确的推荐,推荐系统基于用户的个人信息,例如:不同的评分、历史观察、个人简介等。使用这些系统是非常必要的,但是接收这些信息的方式,以及这些信息的隐私几乎总是被忽视。许多用户不知道他们的信息是如何被接收和使用的。本文将讨论推荐系统如何在不同的在线公司中工作,以及在不损害隐私的情况下使用它们的安全性。鉴于这些系统的广泛使用,一个关于用户隐私和安全的重要问题已经出现。从推荐的系统收集个人信息会增加不必要的信息暴露的风险。本文的结果是,读者将了解推荐系统的功能,他们接收和使用信息的方式,并将讨论针对推荐系统的隐私保护技术。

Rüzgar Türbinlerinin Sismik Davranışı
Elif Altunsu, Onur Güneş, A. Sari
Fosil yakitlarin kullaniminin olumsuz etkileri tüm dünyada yenilenebilir enerji kaynaklannin önem kazanmasma sebep olmuştur. Bununla birlikte rüzgâr enerjisine duyulan ihtiyaç dikkate değer bir artiş göstermiştir. Hem Kuzey Amerika hem de Asya ülkelerinde rüzgâr türbini tasarimmi etkileyecek güçlii depremier yaşanmaktadir. Bu ülkelerin rüzgâr enerjisine yönelimi ile bu çalişmalara yön verilmeye başlanilmiştir. Türkiye’nin rüzgâr enerji potansiyeli Türkiye Rüzgâr Ħaritasi’nda da görüleceği üzere sismik tehlikenin yoğun olduğu bölgelerde toplanmiştir. Bu nedenle rüzgâr türbini tasanminda deprem riskinin dikkate almmasi büyük önem taşimaktadir. Bu doğrultuda çalişma kapsammda, National Renewable Energy Laboratory (NREL) tarafindan geliştirilen 5 MW’lik çelik rüzgar türbini üzerinde hem sismik etkiler hem de rüzgar etkisi tartişilmiştir. Rüzgar simülasyonu yine NREL tarafindan geliştirilen açik kaynakh bir yazihm olan FAST programi yardimi ile gerçekleştirilmiştir. Turbin için sismik analiz ise CAPFOS ve SAP2000 kodlan ile yapilmiştir. Sonuçlar karşilaştirmah olarak yorumlanmiştir. Sismik dalgalarda rüzgâr yüklerinden farkli olarak daha yüksek modlarm etkin olduğu geniş bir frekans araliğinm oluşacağindan dolayi sismik yükler altinda rüzgâr türbinlerinin tepki karakteristiklerini tahmin etmek için daha yüksek modlarm modele dahil edilmesi önem kazanmaktadir. Sismik aktivitesi yüksek bölgelerde rüzgar türbini inşaalannda sismik etkilerin gözardi edilemeyeceği anlaşilmiştir.
化石燃料的使用所带来的负面影响使得可再生能源在全球范围内越来越受到重视。然而,对风能的需求却显著增加。北美和亚洲国家都发生了强烈地震,影响了风力涡轮机的设计。随着这些国家对风能的重视,这些研究也开始有了方向。土耳其的风能潜力主要集中在地震高发区,这一点可以从土耳其风能协会的报告中看出。因此,在风力涡轮机设计中考虑地震风险非常重要。在本研究范围内,对美国国家可再生能源实验室(NREL)开发的 5 兆瓦钢制风力涡轮机的地震和风力影响进行了讨论。风力模拟使用 FAST 进行,这是 NREL 开发的一款开源软件。使用 CAPFOS 和 SAP2000 代码对涡轮机进行了地震分析。对结果进行了比较解释。由于地震波的频率范围很宽,其中较高的模态比风荷载活跃,因此必须将较高的模态纳入模型,以预测风机在地震荷载下的响应特性。人们已经认识到,在地震活动频繁的地区建造风力涡轮机时,地震效应不容忽视。

ANFIS Based UKF-SLAM Path Planning Method 基于ANFIS的UKF-SLAM路径规划方法
Salman Sahib M. Gharib, P. Esmaili
Reducing error in each step of robot motion is one of the important issue in the Simultaneous Localization and Mapping algorithms. Hence, an accurate estimation method can enhance the behavior of the SLAM algorithm in the unknown environment. A hybrid estimation method is presented in this work which is consisted of ANFIS with Unscented Kalman Filter (UKF) to estimate the estate of robots and landmarks. This estimation will be reduced the localization errors of the landmark and robot pose. So, the accuracy of the system will be improved in the planar system. The simulation results based on different environment revealed that the proposed algorithm is adaptable to the different environment with high accuracy, and efficiency in comparison with the previous works such as UKFSLAM and Neuro based UKFSLAM.
减少机器人运动每一步的误差是同步定位与映射算法中的重要问题之一。因此,精确的估计方法可以提高SLAM算法在未知环境中的性能。本文提出了一种混合估计方法,该方法由ANFIS和无气味卡尔曼滤波器(UKF)组成,用于估计机器人和地标的位置。这种估计将减少地标和机器人姿态的定位误差。因此,在平面系统中,系统的精度将得到提高。基于不同环境的仿真结果表明,与UKFSLAM和基于Neuro的UKFSLAM相比,该算法具有较高的精度和效率,能够适应不同的环境。

T. Georgieva-Trifonova, Miroslav Galabov, D. Valcheva, Teodor Kalushkov
The purpose of this paper is to investigate the graph-based representation of the data required for the vector space model (VSM) and PMI (pointwise mutual information)-enriched VSM used for text mining (e.g. text classification). The transformation of a dataset containing free text reviews for online stores in a graph-based form is described and its format that allows to be used by Neo4j graph database management system is proposed. Queries for retrieving the data required for training text mining models are considered; the steps and the actions for their modification when receiving new data are specified. The advantages of the proposed graph-based representation in regard to the maintenance and the extraction of current data needed for retraining data mining models are summarized, in order to prevent loss of performance of results from the execution of the respective data mining task.

Hand and Face Segmentation with Deep Convolutional Networks using Limited Labelled Data 基于有限标记数据的深度卷积网络手和脸分割
Ozge Mercanoglu Sincan, Sinan Gencoglu, M. Bacak, H. Keles
Segmentation is a crucial step for many classification problems. There are many researchers that approach the problem using classical computer vision methods, recently deep learning approaches have been used more frequently in different domains. In this paper, we propose two segmentation networks that mark face and hands from static images for sign language recognition using only a few training data. Our networks have encoder-decoder structure that contains convolutional, max pooling and upsampling layers; the first one is a U-Net based network and the second one is a VGG-based network. We evaluate our models on two sign language datasets; the first one is our Ankara University Turkish Sign Language dataset (AU-TSL) and the second one is Montalbano Italian gesture dataset. Datasets contain background and illumination variations. Also, they are recorded with different signers. We train our models using only 400 images that we randomly selected from video frames. Our experiments show that even when we reduce the training data in half, we can still obtain satisfactory results. Proposed methods have achieved more than 98% precision using 400 frames with both datasets. Our code is available at https://github.com/au-cvml-lab/Hands-and-Face-Segmentation-With-Limited-Data.
分割是许多分类问题的关键步骤。许多研究人员使用经典的计算机视觉方法来解决问题,最近深度学习方法在不同领域的应用越来越频繁。在本文中,我们提出了两种仅使用少量训练数据从静态图像中标记人脸和手的分割网络用于手语识别。我们的网络具有包含卷积层、最大池化层和上采样层的编码器-解码器结构;第一种是基于U-Net的网络,第二种是基于vgg的网络。我们在两个手语数据集上评估了我们的模型;第一个是我们的安卡拉大学土耳其手语数据集(AU-TSL),第二个是蒙塔尔巴诺意大利手势数据集。数据集包含背景和光照变化。此外,它们是由不同的签名者记录的。我们只使用从视频帧中随机选择的400张图像来训练我们的模型。我们的实验表明,即使我们将训练数据减少一半,我们仍然可以获得令人满意的结果。所提出的方法在两个数据集上使用400帧,精度达到98%以上。我们的代码可在https://github.com/au-cvml-lab/Hands-and-Face-Segmentation-With-Limited-Data上获得。

Fuzzy Logic Based Adaptive Cruise Control for Low-Speed Following 基于模糊逻辑的低速跟随自适应巡航控制
Atakan Ondogan, H. Yavuz
Advanced Driver Assistance Systems (ADAS) form the basis of the autonomous driving. Adaptive Cruise Control (ACC), Lane tracking assist and collision avoidance systems etc. are some popular examples of active safety system technologies of ADAS. In order to prevent traffic accidents and ensure the security and comfort in the traffic, there are several intelligent vehicle technologies. Among them, the Adaptive Cruise Control (ACC) is one of which has crucial importance. In this technology, the adjustment of the speed of the vehicle is done by perceiving the environment and controlling through considering obstacles and other vehicle's positioning and speed. This technology involves the usage of high-tech sensor fusion and control techniques. The limitations of the environment are considered and if there is no danger, vehicle keeps its preset speed. If there is a vehicle in front, the vehicle reduces its speed by using dynamically determined equations that involves velocity and acceleration constraints. In this study, a fuzzy logic based adaptive speed control design has been proposed for low speeds. In practice, a fuzzy inference system was designed as a high level operation, and a simple mathematical model based on vehicle dynamics was used as a low level operation. The performance of the proposed system was tested on a scenario designed in a simulation environment and successful results were obtained.
高级驾驶辅助系统(ADAS)是自动驾驶的基础。自适应巡航控制(ACC)、车道跟踪辅助和避碰系统等是ADAS主动安全系统技术的一些流行例子。为了防止交通事故的发生,保证交通的安全性和舒适性,出现了几种智能车辆技术。其中,自适应巡航控制(ACC)是其中至关重要的一种。在该技术中,车辆的速度调整是通过感知环境,并考虑障碍物和其他车辆的位置和速度进行控制。这项技术涉及使用高科技传感器融合和控制技术。考虑了环境的限制,如果没有危险,车辆保持预设的速度。如果前面有一辆车,车辆通过使用包含速度和加速度约束的动态确定方程来降低速度。本研究提出一种基于模糊逻辑的低速自适应速度控制设计。在实际操作中,采用模糊推理系统作为高层操作,采用基于车辆动力学的简单数学模型作为低层操作。在仿真环境中对所设计的场景进行了性能测试,取得了成功的结果。

Adaptive Cruise Control (ACC), Lane tracking assist and collision avoidance systems etc. are some popular examples of active safety system technologies of ADAS. In order to prevent traffic accidents and ensure the security and comfort in the traffic, there are several intelligent vehicle technologies. Among them, the Adaptive Cruise Control (ACC) is one of which has crucial importance. In this technology, the adjustment of the speed of the vehicle is done by perceiving the environment and controlling through considering obstacles and other vehicle's positioning and speed. This technology involves the usage of high-tech sensor fusion and control techniques. The limitations of the environment are considered and if there is no danger, vehicle keeps its preset speed.

A. Gursoy, T. Oner, Ibrahim Senturk, Necla Kircali Gursoy
In this work, we give a software to calculate deductions which are obtained from premises of syllogisms by the help of the SLCD (Syllogistic Logic with Carroll Diagrams) system. Moreover, this software determines whether syllogistic reasoning valid or not based on the calculus system SLCD. This software is also designed to support intelligent systems to make a decision effectively and based on mathematical background.
