Sugarcane Yield Grade Prediction using Random Forest and Gradient Boosting Tree Techniques 基于随机森林和梯度增强树技术的甘蔗产量等级预测
Phusanisa Charoen-Ung, Pradit Mittrapiyanuruk
This paper presents a machine learning based model for predicting the sugarcane yield grade of an individual plot. The dataset used in this work is obtained from a set of sugarcane plots around a sugar mill in Thailand. The features used in the prediction consist of the plot characteristics (soil type, plot area, groove width, plot yield/ yield grade of the last year), sugarcane characteristics (cane class and type), plot cultivation scheme (water resource type, irrigation method, epidemic control method, fertilizer type/formula) and rain volume. We use two predictive algorithms: (i) random forest classification, and (ii) gradient boosting tree classification. The accuracies of our machine learning based predictive methods are 71.83% and 71.64%, respectively. Meanwhile, the accuracies of two non-machine-learning baselines are 51.52% (using the actual yield of the last year as the prediction) and 65.50% (the target yield of each plot is manually predicted by human expert), respectively. This shows that our work is accurate enough to be applied for decision making of sugar mill operation planning.
本文提出了一种基于机器学习的甘蔗单田产量等级预测模型。这项工作中使用的数据集来自泰国一家糖厂周围的一组甘蔗地块。预测使用的特征包括地块特征(土壤类型、地块面积、沟槽宽度、上一年地块产量/产量等级)、甘蔗特征(甘蔗类别和类型)、地块栽培方案(水资源类型、灌溉方式、防治方法、肥料类型/配方)和降雨量。我们使用了两种预测算法:(i)随机森林分类,(ii)梯度增强树分类。我们基于机器学习的预测方法的准确率分别为71.83%和71.64%。同时,两条非机器学习基线的准确率分别为51.52%(使用去年的实际产量作为预测)和65.50%(每个地块的目标产量由人类专家手动预测)。这表明我们的工作具有足够的准确性,可用于糖厂生产计划的决策。

Drone Detection and Identification by Using Packet Length Signature 基于数据包长度签名的无人机检测与识别
Pongjarun Kosolyudhthasarn, V. Visoottiviseth, Doudou Fall, S. Kashihara
Unmanned Aerial Vehicle (UAV) as known as Drone has been becoming very popular around the world. However, a consumer UAV can be controlled from a long distance to record a video of occupants without permission, which causes privacy issues. Existing drone detection systems are required specific hardware and specialists to operate and deploy which are expensive for personal use. In this paper, we propose a drone detection and identification system which utilizes inexpensive commercial off-the-shelf (COTS) hardware and does not requires specialist knowledge to deploy. Our technical approach is to passively listen to the wireless signal between drone and its controller to observe for packet transmission characteristics of each drone. We evaluate our prototype system with three types of drones, which are Spark, AR, and Dobby. Our experiment results illustrate the feasibility of using the data frame length to identify the type of flying drone within 20 seconds.
无人驾驶飞行器(UAV)在世界范围内变得非常流行。然而,消费级无人机可以在未经允许的情况下远距离控制,录制居住者的视频,这会导致隐私问题。现有的无人机探测系统需要特定的硬件和专家来操作和部署,这对于个人使用来说是昂贵的。在本文中,我们提出了一种无人机检测和识别系统,该系统利用廉价的商用现货(COTS)硬件,不需要专业知识来部署。我们的技术方法是被动地监听无人机与其控制器之间的无线信号,观察每架无人机的数据包传输特性。我们用三种类型的无人机来评估我们的原型系统,它们是Spark, AR和多比。实验结果表明,利用数据帧长度在20秒内识别飞行无人机类型是可行的。

Automatic Determination of The G-band Chromosomes Number based on Geometric Features 基于几何特征的g带染色体数目自动确定
Kanuengnij Kubola, P. Wayalun
One of the source used to diagnose the genetic disorders and abnormalities is the light microscopic images of the chromosomes. The first step to check for the abnormalities is to count the chromosome. Many researches have been done on chromosome counting from the images, but the results still need an improvement on complicated case, the cluster of mixing patterns of chromosomes including touching, overlapping, and other patterns. The main objective of this research is to focus and increase the performance of chromosome number determination especially the cluster with the complicated pattern of chromosome. The paper presents a new technique, to determine the number of complicated chromosome image (DNCC) using geometric features including endpoints, and intersection points of the skeletonized chromosome image after pre-processing. The results yield 100% for the clusters with single chromosome, 100% for the clusters with overlapping of two chromosomes, and 79.12% for the cluster of complicated patterns of chromosomes.

A number of medical research is produced by healthcare organizations in Thailand from their routine work, called Routine to Research (R2R). The information from R2R is becoming more important and can be analyzed to find hidden useful knowledge, which may lead to policy of the country. To analyze the data, Association Rule Finding technique and Knowledge Discovery are applied to find relevant patterns and relationship of the related variables in R2R data. The result can be used as evidence for policy makers in the process of policy making. In addition, MedThaiSAGE--a web-based application is also developed to allow users to see the relevant set of rules and visualize related information. The results show that there are some interesting rules that likely to be used by Public Health Policy Makers to develop a policy in order to improve and provide Thai people better health care services.

Load Distribution of Software-Defined Networking Based on Controller Performance 基于控制器性能的软件定义网络负载分配
Kanok Konglar, Yuthapong Somchit
Software-Defined Networking (SDN) enabled by OpenFlow is a new paradigm of the network that is managed by a single centralized controller. In a large-scale network, distributed controller mechanism using multiple controllers is introduced to solve a problem of single point of failure. This mechanism requires load balancing to balance the loads of the controllers. The current load controller methods still have some issues. This work proposes a load balance method called Load Distribution mechanism and an algorithm based On controller Performance (LDOP). The LDOP can reduce loads of the overloaded controller by migrating switches to other controllers. Moreover, LDOP can reduce the impact when many controllers are overloaded. In this work, we evaluate the performance of LDOP by simulation. The experimental results show that LDOP mechanism can reduce loads of overloaded controller and does not make other controllers become overloaded. In case of many controllers are overloaded, it also reduces the impact of this. In addition, textbfLDOP also reduces the number of messages that controllers use in load balancing compared to other protocols.
OpenFlow支持的软件定义网络(SDN)是由单个集中控制器管理的网络的新范例。在大规模网络中,采用多控制器的分布式控制器机制来解决单点故障问题。这种机制需要负载均衡来平衡控制器的负载。目前的负载控制方法还存在一些问题。本文提出了一种负载均衡方法——负载分配机制和一种基于控制器性能(LDOP)的算法。LDOP可以通过将交换机迁移到其他控制器来减轻过载控制器的负载。此外,LDOP可以减少许多控制器过载时的影响。在这项工作中,我们通过仿真来评估LDOP的性能。实验结果表明,LDOP机制可以减少过载控制器的负载,并且不会使其他控制器过载。在许多控制器过载的情况下,它也减少了这种影响。此外,与其他协议相比,textbfLDOP还减少了控制器在负载平衡中使用的消息数量。

Thitiphong Raksarikorn, Thanapat Kangkachit
Facial expression classification p lays c rucial role in human-computer interaction. A large number of automated methods have been proposed since the past decades. Recently, deep learning is broadly applied in computer vision field as well as facial expression classification. The reasons are to avoid complex feature extraction process and obtained satisfied classification p erformance. In this work, w e p ropose a deep convolutional neural networks (CNNs) model, inspired from XCEPTION, to classify seven groups of facial expressions. To efficiently use o f m odel parameters, the model a rchitecture has only 2.2 million parameters which is about 10 times less than XCEPTION. The experimental results on FER-2013 dataset show that our model offers comparable accuracy (0.7169) to the state-of-the-art methods and the upper-bound level of human accuracy $( 0.65 pm 5)$. In addition, our model uses less number of parameters than the state-of-the-art models and without using extra features and data augmentation.
面部表情分类在人机交互中起着重要的作用。自过去几十年以来,已经提出了大量的自动化方法。近年来,深度学习在计算机视觉和面部表情分类等领域得到了广泛的应用。其原因是避免了复杂的特征提取过程,获得了满意的分类性能。在这项工作中,我们提出了一个受XCEPTION启发的深度卷积神经网络(cnn)模型,用于对七组面部表情进行分类。为了有效地利用模型参数,模型a架构只有220万个参数,比XCEPTION少了大约10倍。在FER-2013数据集上的实验结果表明,我们的模型提供了与最先进的方法相当的精度(0.7169)和人类精度的上限(0.65 pm 5)$。此外,我们的模型比最先进的模型使用更少的参数,并且没有使用额外的特征和数据增强。

LSB Rotation and Inversion Scoring Approach to Image Steganography 图像隐写的LSB旋转和反转评分方法
Ryan A. Subong, Arnel C. Fajardo, Yoon-Joong Kim
The less obvious that an image has been modified, the less it will be suspected of containing a secret message or image. This paper proposes an image steganographic approach wherein the bit information of the secret message replaces the LSBs (least significant bit) of the RGB (red green blue) bytes of the cover image just like many of the LSB image steganography methods, except that the bits of the secret message undergo a series of evaluated and scored bit rotation and inversion operations prior replacement. Using MSE and PSNR as a measure of image quality, the stego image generated by this proposed approach produced lesser distortion than the existing four bits per byte replacement approach of LSB Replacement and Adaptive LSB Embedding algorithms. The proposed approach however does not offer significant improvement of robustness in terms of security.
图像被修改的越不明显,怀疑它包含秘密消息或图像的可能性就越小。本文提出了一种图像隐写方法,其中秘密消息的位信息替换封面图像RGB(红绿蓝)字节的LSB(最低有效位),就像许多LSB图像隐写方法一样,只是秘密消息的位在替换之前经历了一系列评估和评分的位旋转和反转操作。使用MSE和PSNR作为图像质量的度量,该方法生成的隐写图像比现有的LSB替换和自适应LSB嵌入算法的每字节4位替换方法产生更小的失真。然而,所提出的方法在安全性方面并没有提供显著的鲁棒性改进。

The proposed approach however does not offer significant improvement of robustness in terms of security.","PeriodicalId":338973,"journal":{"name":"2018 15th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127376078","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}

Integrated Well-being IoT System for Healthiness (I-WISH) has been developed to improve the quality of life, wellbeing, healthiness, and behavior by using Internet of Things technology. The concept of I-WISH system is to integrate between a 4WD Robot Car and the variety of sensors for monitoring and analyzing the improper environment inside the buildings. All sensors are used to sense improper environment. The collected data will be sent to real time Firebase database system via Internet and sharing to the mobile application which provides useful features such as notification and appropriate suggestion. As a result, I-WISH system will encourage the users to aware of the improper environment and realize the importance of healthiness. This system is considered as a new tool that can help improving the quality of human life.
I-WISH (Integrated well - IoT System for health)是一种利用物联网技术改善生活质量、福祉、健康和行为的健康物联网系统。I-WISH系统的概念是将一辆四轮驱动机器人汽车与各种传感器集成在一起,用于监测和分析建筑物内的不当环境。所有的传感器都用来感知不合适的环境。收集到的数据将通过互联网实时发送到Firebase数据库系统,并共享到提供通知和适当建议等有用功能的移动应用程序。因此,I-WISH系统将鼓励用户意识到不适当的环境,并意识到健康的重要性。该系统被认为是一种有助于提高人类生活质量的新工具。
