Md. Naimul Islam Suvon, R. Khan, Mehebuba Ferdous
Automatic number plate identification in today's world plays a vital role in vehicle tracking and organization. Our proposed model of automation in the detection and recognizing vehicles through the use of number plate computerization is expected to create a new scope of evolution for large cities. The system can be used for the parking system of motor vehicles, as well as to collect tolls. The detection of the Bangla number plates from different cities and multi-class vehicles is the first step of the proposed system. The number plate detection has been performed with the computer vision approach, and the You Only Look Once v3 (YOLOv3) algorithm. Next, the Tesseract optical character recognition system, in conjunction with the Bangla character recognition model, has been used for vehicle indexing and convolutional neural network for the character recognition from the detected number plate. Numerical results demonstrate that the accuracies of license plate detection for the computer vision and YOLOv3 are 91% and 95%, respectively. For the character recognition, the accuracy for Tesseract and convolutional neural network are 90% if the license plate is detected and cropped successfully and 91.38%, respectively. Finally, our system has been tested using the convolutional neural network method in an environment of real-world where our system's Pi Camera captured video as input, which has a total of 18 different cars. From 18 cars, it has successfully detected 17 cars, which makes our overall system accuracy 88.89%.
车牌自动识别在当今世界的车辆跟踪和组织中起着至关重要的作用。我们提出的自动检测和识别车辆的模型,通过使用车牌电脑化,有望为大城市创造一个新的发展范围。该系统可用于机动车的停车系统,也可用于收取通行费。从不同城市和不同类别的车辆中检测孟加拉车牌是拟议系统的第一步。车牌检测采用计算机视觉方法和You Only Look Once v3 (YOLOv3)算法进行。接下来,将Tesseract光学字符识别系统与孟加拉字符识别模型结合,用于车辆索引,并将卷积神经网络用于从检测到的车牌中识别字符。数值结果表明,计算机视觉和YOLOv3的车牌检测准确率分别为91%和95%。对于字符识别,在车牌检测和裁剪成功的情况下,Tesseract和卷积神经网络的准确率分别为90%和91.38%。最后,我们的系统已经在现实世界的环境中使用卷积神经网络方法进行了测试,我们系统的Pi Camera捕获视频作为输入,总共有18辆不同的汽车。从18辆车中,它成功检测了17辆车,使我们的整体系统准确率达到88.89%。

Development of Exercise Promotion System Using Smartphone and AI Speaker 基于智能手机和AI音箱的运动促进系统开发
Ryota Arai, M. Ohsuga
The average human life expectancy has been gradually extended; thus, development of novel approaches to extend healthy life expectancy have gained considerable research attention. Although it is well-known that habitual exercise is an effective way of extending healthy life expectancy, we have found that few people actually continue exercising regularly. Consequently, we have devised a system for promoting exercise using a smartphone and an artificial intelligence (AI) speaker. After confirming that the number of repetitions of an exercise recommended to a user (via the exercise content presented to them) can be detected using smartphone sensors, we integrated the smartphone and AI speaker into one system via the cloud. This system allows the user to receive advice from the AI speaker after exercising. In the future, we will investigate whether the proposed method can significantly encourage changes in exercise-related awareness and behavior compared to existing smartphone apps used for health management.
人类的平均预期寿命逐渐延长;因此,发展新的方法来延长健康预期寿命已经获得了相当大的研究关注。虽然众所周知,习惯性锻炼是延长健康寿命的有效方式,但我们发现很少有人真正坚持定期锻炼。因此,我们设计了利用智能手机和人工智能(AI)扬声器促进运动的系统。在确认可以使用智能手机传感器检测到推荐给用户的运动(通过向他们展示的运动内容)的重复次数后,我们通过云将智能手机和人工智能扬声器集成到一个系统中。该系统允许用户在锻炼后接收AI扬声器的建议。在未来,我们将研究与现有的用于健康管理的智能手机应用程序相比,所提出的方法是否能显著促进运动相关意识和行为的改变。

Wideband Conformal Polymeric Based Antenna for Microwave Medical Imaging System 微波医学成像系统宽带共形聚合物天线
M. Limbah, H. Lago, P. Soh, K. Teo
In this work, a conformal antenna designed using polydimethylsiloxane (PDMS) is presented, with copper used as its conducting elements. Such material combination enabled the realization of a highly flexible antenna structure for potential implementation on the human body in microwave imaging systems. This antenna is designed based on a planar monopole aimed at operation in the lower ultra-wideband (UWB) frequencies. The choice of this band is to enable a deeper penetration of radiation into the human body. It operates from 2.92 to 4.75 GHz, with a bandwidth of 1826 MHz and a gain of 2.41 dB in its planar condition. When evaluated in a bent configuration with a radius of 20 mm, 40 mm and 60 mm, a bandwidth of 47.59% (1826 MHz), 45.72% (1741 MHz) and 42.68% (1770 MHz) with a gain of 2.41 dB, 2.73 dB and 3 dB is observed respectively. These results indicate that the antenna can be potentially be used on a human body for microwave imaging purposes.

Experimenting Deep Convolutional Visual Feature Learning using Compositional Subspace Representation and Fashion-MNIST 基于组合子空间表示和Fashion-MNIST的深度卷积视觉特征学习实验
M. Teow
This paper introduces a formal framework to model the convolutional visual feature learning in a convolutional neural network, which is called compositional subspace representation. The objective is to explain the convolutional visual feature learning computation using a rigid and structural method. The theoretical basis of the proposed framework is, the best way for representation to model a complex learning function is by using a composition of simple two-dimensional piecewise-linear functions to form a multilayers successive cascaded projection function for complex representation. Under the same hypothesis, the proposed framework also explains the hierarchical feature learning representation in a convolutional neural network, the well-acknowledged significant advantage of convolutional neural networks in visual computing. The proposed framework has experimented with image classification using the Fashion-MNIST dataset. Experimental assessments using learning curves analysis, confusion matrix, and visual assessment are presented and discussed. The experimental results were consistent with the theoretical expectation.

Neural Networks Based on Latent Dirichlet Allocation For News Web Page Classifications 基于潜在Dirichlet分配的神经网络用于新闻网页分类
Adel R. Alharbi, Shwaa D. Alharbi, Amer Aljaedi, Oluwatobi Akanbi
Any popular news website in our modern life, offering details to millions of users every day. Although computer technology continues to grow, the number of disease data is rising. How to structure the document to enable data recognition dynamically has become one of the main challenges for sophisticated web services. Traditional systematic classification of news text requires not only a lot of human and financial assets but it also hardly accomplishes fast classification function. In this work, we introduce a new method relying on both the Latent Dirichlet Allocation and the Neural Networks that are used in the Arabic document classification. Our approach adopts the Vector Space Model to interpret documents in applications for the text classification. In this process, the text is represented as a term vector; n-grams. These methods can not distinguish semantic or textual content; this results in considerable space for features and semantic losses. In this research, the new proposal utilizes a “topics” sampled as text characteristics by the Latent Dirichlet Allocation method. Effectively it eliminates the problems described. We have extracted important themes (topics) of all the texts. Each theme is identified by a different descriptor distribution, and then each text is depicted on the vectors of certain themes. Our experiments indicate that the proposed solution is capable of achieving high efficiency with an accuracy rate of 85.11% for the Arabic text classification task.
任何在我们现代生活中流行的新闻网站,每天为数百万用户提供细节。尽管计算机技术不断发展,但疾病数据的数量也在不断增加。如何构建文档以动态地实现数据识别已成为复杂web服务的主要挑战之一。传统的新闻文本系统分类不仅需要耗费大量的人力和财力,而且难以实现快速分类的功能。在这项工作中,我们引入了一种依赖于潜在狄利克雷分配和神经网络的新方法,这些方法用于阿拉伯语文档分类。我们的方法采用向量空间模型来解释文本分类应用中的文档。在这个过程中,文本被表示为一个术语向量;字格。这些方法不能区分语义或文本内容;这给特征和语义损失留下了相当大的空间。在本研究中,新提案利用潜在狄利克雷分配方法采样的“主题”作为文本特征。它有效地消除了所描述的问题。我们摘录了所有文本的重要主题。每个主题由不同的描述符分布来标识,然后每个文本在特定主题的向量上进行描绘。实验表明,该方法对阿拉伯文本分类任务具有较高的效率,准确率达到85.11%。

Improvement of ACTT that is Autonomous Driving Technologies Support Platform for Education and Research 自动驾驶技术教育与科研支撑平台ACTT的改进
Naohiro Nakamoto, Hiroyuki Kobayashi
In recent years, the development of autonomous driving technologies has been very active in the world. However, the shortage of human resources is a serious problem. Therefore, in Japan, the autonomous driving IT human resources strategy has been proposed. Although, the problem of shortage cannot be solved because it is aimed at the excellent top personnel. In order to solve the problem, the authors are developing a platform that contributes to the realization of the problem. In this paper, the authors report on the improvement of ACTT, which is an autonomous driving assistance platform developed in the past study. Previous ACTT had complex configurations. Therefore, the authors improved them and conducted evaluation experiments as a new. In addition, in order to implement automatic driving technologies, ROS package “Navigation Stack” has been implemented in the simulator. In the future, the authors will implement it into current ACTT to complete the platform.

Fuzzy Logic Control of Exothermic Batch Process 放热间歇过程的模糊逻辑控制
Wan Ying Chai, M. K. Tan, K. Teo, H. Tham
Thermal runaway of exothermic reaction, especially with batch chemical plants, is a critical issue because it can affect production quantity and quality, causes profit loss, and in worst case can threaten the safety of workers and lead to plant accident. The conventional PID controller which is usually used in many industries needs to be operated under supervision in order to perform the temperature control well. In this work, Mamdani type fuzzy logic controller is proposed to track an optimal reference temperature profile. Both process model and proposed controller are simulated using MATLAB. The results show the designed fuzzy logic controller is well-performed in set point tracking and able to cope with the simulated disturbance condition.

The results show the designed fuzzy logic controller is well-performed in set point tracking and able to cope with the simulated disturbance condition.","PeriodicalId":300885,"journal":{"name":"2020 IEEE 2nd International Conference on Artificial Intelligence in Engineering and Technology (IICAIET)","volume":"19 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116340913","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}

Metaheuristic Multi-Hop Clustering Optimization for Energy-Efficient Wireless Sensor Network 节能无线传感器网络的元启发式多跳聚类优化
Vincent Chung, N. Tuah, Kit Guan Lim, M. K. Tan, I. Saad, K. Teo
Energy-efficient optimization algorithm in wireless sensor network (WSN) is often based on solely cluster routing or multi-hop routing. The cluster optimization algorithm will form a cluster network by dividing the sensor nodes into few clusters where each cluster has a cluster head (CH) for data collection. On the other hand, multi-hop optimization algorithm will form a multi-hop network by transmitting data to base station (BS) through data multi-hopping between sensor nodes. However, cluster optimization algorithm suffers from the overburdens of CH nodes, while multi-hop optimization algorithm suffers from the overburdens of nodes which are near to the BS. Therefore, Genetic Algorithm-Cuckoo Search (GACS) is proposed and developed based on the multi-hop clustering model in this paper. GACS optimizes both intra-cluster and inter-cluster communications to enhance energy efficiency in WSN, extending the network lifetime. Based on the performance evaluation, GACS outperforms both Genetic Algorithm (GA)-based cluster optimization algorithm and Cuckoo Search (CS)-based multi-hop optimization algorithm.
无线传感器网络中的节能优化算法通常基于单簇路由或多跳路由。聚类优化算法将传感器节点分成几个簇,每个簇有一个簇头(CH)来收集数据,从而形成一个聚类网络。另一方面,多跳优化算法将通过传感器节点之间的数据多跳向基站(BS)传输数据,形成多跳网络。但聚类优化算法存在CH节点的过载问题,而多跳优化算法存在靠近BS节点的过载问题。为此,本文提出并发展了基于多跳聚类模型的遗传算法-布谷鸟搜索(GACS)。GACS优化了集群内和集群间的通信,提高了WSN的能源效率,延长了网络寿命。基于性能评价,GACS优于基于遗传算法(GA)的聚类优化算法和基于布谷鸟搜索(CS)的多跳优化算法。
