In this work, we present a performance comparison of the Multi Layer Perceptron (MLP), Support Vector Machines (SVM) and Voted Perceptron (VP) when applied to a social signal processing task. The signal processing task is in the field of computational politics where the aim is to predict the political parties of American congress members based on their response to certain questions. Using this dataset which is publicly available, we investigate the use of four methods to impute or approximate missing values. The four imputed datasets are used to train MLP, SVM and VP classifiers to associate the congress members' responses to their political party affiliation and we compare the results from the three classifiers. The aim is to design a practical system or model to be able to predict another person's political affiliations based on their responses to similar questions. The obtained experimental results suggest that machine learning classifiers can be used to accurately predict an individual's political leaning.
在这项工作中,我们提出了多层感知机(MLP),支持向量机(SVM)和投票感知机(VP)在应用于社会信号处理任务时的性能比较。信号处理任务属于计算政治领域,其目的是根据美国国会议员对某些问题的回答来预测他们所属的政党。使用这个公开可用的数据集,我们研究了使用四种方法来估算或近似缺失值。我们使用这四个输入的数据集来训练MLP、SVM和VP分类器,将国会议员的回答与其所属政党联系起来,并比较这三个分类器的结果。其目的是设计一个实用的系统或模型,能够根据一个人对类似问题的回答来预测他的政治立场。实验结果表明,机器学习分类器可以用来准确地预测个人的政治倾向。

In this paper, the design, analysis and numerical results of back scattering field of winged almond model with ammunition and without ammunition are presented. Simulations with using Physical Optics (PO) method in Ansys HFSS software for monostatic Radar Cross Section (RCS) were made in 1 GHz and 9 GHz. By using PO method to obtain the total scattered field received part of the radar, the body of the target is seperated into number of facets, then all these facets scattered field components are super imposed. When the electrical size of the target is twice as large as the wavelength, the order diffraction field is not considered. The fractured area from the first order will be sufficient to calculate the RCS of the target. Effects of ammunition quantity of modeled winged almon model with ammunition on RCS are compared in different frequencies.

Fire may cause people in the building to be scared, distracted. In that case, some evacuation systems may help people to leave the building safely. This paper proposes a technique to explore a wayfinding during fire. Wayfinding depends on building type. We also investigated the possible influence of smoke, light and distance on route determination for fire evacuation. When the fire occurs, the system provides evacuation route guidance to people for them to be able to avoid hazard. It is important to optimize the evacuation route for minimum effects of dangerous conditions. Fire evacuation system can recommend the shortest and safety route. Here, Particle Swarm Optimization is used to optimize the evacuation route. On the other advantage of Particle Swarm Optimization is that it is easy to implement and has very few parameters.

Computer-aided detection (CAD) provides an efficient way to assist doctors to interpret fundus images. In a CAD system, retinal vessel (RV) detection is an important step to identify the retinal disease regions automatically and accurately. However, RV detection is still a challenging problem due to variations in morphology of the vessels on a noisy background. In this paper, we formulate the detection task as a classification problem and solve it using a convolutional neural network (CNN) as a two-class classifier. The proposed model has 2 convolution layers, 2 pooling layers, 1 dropout layer and 1 loss layer. The proposed CNN achieves better performance and significantly outperforms the state-of-the-art for automatic retinal vessel segmentation on the DRIVE dataset with 91.78% accuracy and 0.96743 AUC score. We further compare our result with several state of the art methods based on AUC values. The comparison shows that our proposal yields the second best AUC value. This demonstrates the efficiency of the proposed method which has no pre-processing steps.
计算机辅助检测(CAD)提供了一种有效的方法来帮助医生解释眼底图像。在CAD系统中,视网膜血管检测是自动准确识别视网膜病变区域的重要步骤。然而,由于在噪声背景下血管形态的变化,RV检测仍然是一个具有挑战性的问题。在本文中,我们将检测任务描述为一个分类问题,并使用卷积神经网络(CNN)作为两类分类器来解决它。该模型有2个卷积层、2个池化层、1个dropout层和1个loss层。本文提出的CNN在DRIVE数据集上的视网膜血管自动分割准确率为91.78%,AUC分数为0.96743,取得了更好的性能,明显优于目前的技术水平。我们进一步将我们的结果与基于AUC值的几种最先进的方法进行比较。比较表明,我们的建议产生第二好的AUC值。验证了该方法的有效性,该方法不需要任何预处理步骤。

In last few decades, as a result of the advances in microelectromechanical systems, Wireless Sensor Networks (WSNs) have gained a considerable attention due to their low-cost, low-power and small-scale sensor nodes which are used to integrate sensing, processing, communicating capabilities to solve many different real world problems. The placement of sensor nodes is a very important step to cover the theater of these application areas. Increasing the coverage of WSN system is one of the important research interests to determine the quality of service of the system. The location of sensor nodes can be determined by humans to increase the coverage area. However, in the remote or hostile environments, the random deployment of sensor nodes is needed to be used. In this paper, the different random deployment techniques have been studied, and the experimental results are obtained have been shared to show the effectiveness of these techniques. Finally, the alternative approaches are mentioned to guide the researchers, as well.

Rail systems are one of the most important transportation methods used in today's world. The abnormalities that occur on railway tracks due to various causes result in breakdowns and accidents. For this reason, railway tracks must be periodically inspected. This study proposes a new approach for rail inspection. Today, the railway inspection process is generally performed using computer vision. But the oil and dust residues occurring on railway surfaces can be detected as an false-positive by the image processing software can lead to loss of time and additional costs in the railway maintenance process. In this study, a hardware and software architecture are presented to perform railway surface inspection using 3D laser camera and deep learning. The use of 3D laser cameras in railway inspection process provides high accuracy rates in real time. The reading rate of laser cameras to read up to 25.000 profiles per second is another important advantage provided in real time railway inspection. Consequently, a computer vision-based approach in which 3D laser cameras that could allow for contact-free and fast detection of the railway surface and lateral defects such as fracture, scouring and wear with high accuracy are used in the railway inspection process was proposed in the study.
铁路系统是当今世界最重要的运输方式之一。铁路轨道由于各种原因发生的异常导致故障和事故。因此,铁路轨道必须定期检查。本研究提出了一种新的钢轨检测方法。今天,铁路检查过程通常使用计算机视觉进行。但是铁路表面的油污和灰尘残留会被图像处理软件检测为假阳性,这会导致铁路维护过程中的时间损失和额外成本。在本研究中,提出了一种利用三维激光相机和深度学习进行铁路表面检测的硬件和软件架构。三维激光摄像机在铁路检测过程中的应用,提供了较高的实时性。激光相机的读取速率高达每秒25,000个轮廓是实时铁路检测提供的另一个重要优势。因此,本研究提出了一种基于计算机视觉的方法,该方法可以在铁路检测过程中使用3D激光相机,该方法可以实现对铁路表面和断裂、冲刷和磨损等横向缺陷的无接触快速检测,并且精度高。

Molecular Communication (MC) is a new multidisciplinary subject concerning medicine, biology, and communication engineering. MC concept is introduced for modeling of communication of nano/micro scale devices. In MC systems, chemical signals carrying information in gaseous or liquid media are used. Similar to other communication systems, in MC sending information from transmitter to receiver with minimum error is one of the most important goals. In MC systems due to physical characteristics of medium, higher rates of inter symbol interference (ISI) and noise increase error probability. Figures of receiver mechanisms and signal detection techniques are therefore the main factors to be tuned for decreasing error probability. In this view, so far, many receiver models such as reversible adsorption and desorption (A&D), protrusion method, ligand receptor, and linear catalytic or CAT receiver models have been introduced. In this study, these models and the results obtained through their implementation are investigated and briefly reviewed.
分子通信是一门集医学、生物学和通信工程于一体的新兴多学科。将MC概念引入到纳/微器件的通信建模中。在MC系统中,使用在气体或液体介质中携带信息的化学信号。与其他通信系统类似,在MC中,以最小的误差将信息从发送器发送到接收器是最重要的目标之一。在MC系统中,由于介质的物理特性,较高的码间干扰率和噪声增加了误码率。因此,接收机机制和信号检测技术的数字是降低误差概率的主要因素。在此看来,迄今为止,已经介绍了许多受体模型,如可逆吸附和解吸(A&D),突出法,配体受体,线性催化或CAT受体模型。在本研究中,对这些模型及其实现所获得的结果进行了调查和简要回顾。

With the development of technology, people are entering the virtual world more and more. Parallel to this, the internet becomes a bigger network every day and it gets a complex structure depending on this growth. Achieving the desired information with structred data becomes an increasingly important problem. One of the useful ways to find solution for this problem is to divide this complex data into categories by text mining methods. By creating semantic similarities with this categorization, data can be achieved effectively and quickly. In this study, it is aimed to classify the news text data that have four different categories (economy, politics, sports and health) with different feature extraction and term weighting methods using different text mining techniques and to test the efficiency and success of the methods. By the proposed method, 100% classification success rate was obtained on news texts.
随着科技的发展,越来越多的人进入虚拟世界。与此同时,互联网每天都在成为一个更大的网络,它的结构也随着这种增长而变得复杂。利用结构化数据获取所需的信息已成为一个日益重要的问题。通过文本挖掘方法将这些复杂的数据进行分类是解决这一问题的有效方法之一。通过使用这种分类创建语义相似性,可以有效而快速地获得数据。本研究旨在使用不同的文本挖掘技术,对经济、政治、体育和健康四个不同类别的新闻文本数据,采用不同的特征提取和术语加权方法进行分类,并测试方法的效率和成功率。该方法对新闻文本的分类成功率达到100%。
