In this study, we compare a cluster-based whale optimization algorithm (WOA) with an uncombined method to find a more optimized solution for a traveling salesman problem (TSP). The main goal is to reduce the time of solving a TSP. First, we solve the TSP with the Whale optimization algorithm, later we solve it with the combined method of solving TSP which uses the clustering method, called BIRCH (balanced iterative reducing and clustering using hierarchies). Birch builds a clustering feature (CF) tree and then applies one of the clustering methods (for ex. K-means) to cluster data. Experiments performed on three datasets show that the convergence time improves by using the combined algorithm.

在这项研究中,我们比较了基于集群的鲸鱼优化算法(WOA)和非组合方法,以找到一个更优化的旅行推销员问题(TSP)的解决方案。主要目标是减少求解TSP的时间。首先,我们使用Whale优化算法求解TSP,然后我们使用聚类方法求解TSP的组合方法,称为BIRCH (balanced iterative reduction and clustering using hierarchies)。Birch构建了一个聚类特征(CF)树,然后应用其中一种聚类方法(例如K-means)来聚类数据。在三个数据集上进行的实验表明,该组合算法提高了收敛时间。

This paper presents a webserver for Indonesian fishermen, to support fishing activities. This is one of the sub-systems of e-Nelayan (in English: eFisherman) architecture, which was connected to e-Nelayan Apps; it helps to provide interaction between two users, including the administrators and fishermen. Using hypertext preprocessor (PHP) language, the website was developed to function on an Apache web server, with the adaptation of my structured query language (MySQL) framework for the database. This system was subsequently divided into two parts: (1) the front-end, which is responsible for the accessibility of data collection and (2) the back-end, where administrators update or modify crucial information: price, fishing result, illegal activity report, save our ship! (SOS) potential fish zone, and ship tracking. The administrators are unable to update the real-time weather information for the front-end part. The application was found to record the information obtained from the fishermen through the e-Nelayan apps and meteorology, climatology, and geophysical agency (BMKG in Indonesian). This web system is expected to carry out the following functions: to ensure easier interactions between fishermen and administrators, to enable easy update of information, to promote monitoring and recording of results, and to ensure fishermen’s safety.
本文为印尼渔民提供了一个网络服务器,以支持渔业活动。这是e-Nelayan(英文:fisherman)架构的一个子系统,它连接到e-Nelayan应用程序;它有助于提供两个用户之间的交互,包括管理员和渔民。本网站采用超文本预处理器(PHP)语言,在Apache web服务器上开发,数据库采用我的结构化查询语言(MySQL)框架。该系统随后分为两个部分:(1)前端,负责数据收集的可访问性;(2)后端,管理员更新或修改关键信息:价格、捕捞结果、非法活动报告、拯救我们的船!(SOS)潜在鱼区,以及船舶跟踪。管理员无法更新前端的实时天气信息。该应用程序被发现记录了通过e-Nelayan应用程序和气象、气候和地球物理机构(印度尼西亚的BMKG)从渔民那里获得的信息。这个网上系统预期可实现以下功能:确保渔民与行政人员之间更容易互动,方便更新资料,促进监测和记录结果,以及确保渔民的安全。

Person re-identification (Person Re-ID) is a research direction on tracking and identifying people in surveillance camera systems with non-overlapping camera perspectives. Despite much research on this topic, there are still some practical problems that Person Re-ID has not yet solved, in reality, human objects can easily be obscured by obstructions such as other people, trees, luggage, umbrellas, signs, cars, motorbikes. In this paper, we propose a multibranch deep learning network architecture. In which one branch is for the representation of global features and two branches are for the representation of local features. Dividing the input image into small parts and changing the number of parts between the two branches helps the model to represent the features better. In addition, we add an attention module to the ResNet50 backbone that enhances important human characteristics and eliminates irrelevant information. To improve robustness, the model is trained by combining triplet loss and label smoothing cross-entropy loss (LSCE). Experiments are carried out on datasets Market1501, and duke multi-target multi-camera (DukeMTMC) datasets, our method achieved 96.04% rank-1, 88,11% mean average precision (mAP) on the Market1501 dataset, and 88.78% rank-1, 78,6% mAP on the DukeMTMC dataset. This method achieves performance better than some state-of-the-art methods.
人员再识别(Person Re-ID)是监控摄像系统中无重叠视角下对人员进行跟踪和识别的研究方向。尽管这方面的研究很多,但仍有一些实际问题没有解决,在现实中,人的物体很容易被其他人、树木、行李、雨伞、标志、汽车、摩托车等障碍物遮挡。在本文中,我们提出了一个多分支深度学习网络架构。其中一个分支用于表示全局特征,两个分支用于表示局部特征。将输入图像分割成小的部分,并在两个分支之间改变部分的数量,有助于模型更好地表示特征。此外,我们在ResNet50主干中添加了一个注意力模块,增强了重要的人类特征并消除了不相关的信息。为了提高模型的鲁棒性,将三重态损失和标记平滑交叉熵损失(LSCE)相结合来训练模型。在Market1501数据集和duke多目标多相机(DukeMTMC)数据集上进行实验,我们的方法在Market1501数据集上的平均精度(mAP)为96.04%,在DukeMTMC数据集上的平均精度(mAP)为88.78%。这种方法的性能优于一些最先进的方法。

One of the main challenges in developing the internet of things (IoT) is the existence of availability problems originated from the low-rate distributed denial of service attacks (LRDDoS). The complexity of IoT makes the LRDDoS hard to detect because the attack flow is performed similarly to the regular traffic. Integration of software defined IoT (SDN-Enabled IoT) is considered an alternative solution for overcoming the specified problem through a single detection point using machine learning approaches. The controller has a resource limitation for implementing the classification process. Therefore, this paper extends the usage of Feature Importance to reduce the data complexity during the model generation process and choose an appropriate feature for generating an efficient classification model. The research results show that the Gaussian Naïve Bayes (GNB) produced the most effective outcome. GNB performed better than the other algorithms because the feature reduction only selected the independent feature, which had no relation to the other features.
低速率分布式拒绝服务攻击(LRDDoS)导致的可用性问题是物联网发展面临的主要挑战之一。物联网的复杂性使得LRDDoS很难被检测到,因为攻击流程与常规流量类似。软件定义物联网(SDN-Enabled IoT)的集成被认为是使用机器学习方法通过单个检测点克服指定问题的替代解决方案。控制器具有实现分类过程的资源限制。因此,本文扩展了特征重要性的使用,以降低模型生成过程中的数据复杂性,并选择合适的特征生成高效的分类模型。研究结果表明,高斯Naïve贝叶斯算法(GNB)产生的结果最为有效。GNB算法的性能优于其他算法,因为特征约简只选择独立的特征,而与其他特征无关。

A reliable transit service can motivate commuters to switch their travelingmode from private to public. Providing necessary information to passengerswill reduce the uncertainties encountered during their travel and improveservice reliability. This article addresses the challenge of predicting dynamictravel times in urban areas where real-time traffic flow information isunavailable. In this perspective, a hybrid travel time estimation model(HTTEM) is proposed to predict the dynamic travel time using the predictedtravel times of the machine learning model and the preceding trip details. Theproposed model is validated using the location data of public transit buses of,Tumakuru, India. From the numerical results through error metrics, it is foundthat HTTEM improves the prediction accuracy, finally, it is concluded that theproposed model is suitable for estimating travel time in urban areas withheterogeneous traffic and limited traffic infrastructure.
可靠的交通服务可以促使通勤者将他们的出行方式从私人转向公共。向乘客提供必要的信息将减少他们在旅行中遇到的不确定性,提高服务的可靠性。本文解决了在无法获得实时交通流信息的城市地区预测动态出行时间的挑战。从这个角度出发,提出了一种混合行程时间估计模型(HTTEM),利用机器学习模型的预测行程时间和之前的行程细节来预测动态行程时间。利用印度图马库鲁的公共交通公交车的位置数据对所提出的模型进行了验证。从误差度量的数值结果来看,HTTEM提高了预测精度,最后得出结论,该模型适用于交通异质性和交通基础设施有限的城市地区的出行时间估计。

Loss of the capability to talk or hear has psychological and social effects onthe affected individuals due to the absence of appropriate interaction. SignLanguage is used by such individuals to assist them in communicating witheach other. This paper proposes a glove called GloSign that can convertAmerican sign language to characters. This glove consists of flex and inertialmeasurement unit (IMU) sensors to identify gestures. The data from glove isuploaded on IoT platform, which makes the glove portable and wireless. Thedata from gloves is passed through a k-nearest neighbors (KNN) Algorithmmachine learning algorithm to improve the accuracy of the system. Thesystem was able to achieve an accuracy of 96.8%. The glove can also be usedto form sentences. The output is displayed on the screen or is converted tospeech. This glove can be used in communicating with people who don’t knowsign language.
由于缺乏适当的互动,说话或听力的丧失对患者的心理和社会产生了影响。这些人使用手语来帮助他们彼此交流。本文提出了一种名为GloSign的手套,它可以将美国手语转换为文字。这款手套由弯曲和惯性测量单元(IMU)传感器组成,用于识别手势。手套的数据上传到物联网平台,使手套具有便携性和无线性。来自手套的数据通过k近邻(KNN)算法(机器学习算法)传递,以提高系统的准确性。该系统能够达到96.8%的准确率。手套也可以用来造句。输出显示在屏幕上或转换为语音。这只手套可以用来和不懂手语的人交流。

Time restrictions and lack of precision demand that the initial technique be abandoned. Even though the remaining datasets had fewer identified classes than initially planned for the study, the labels were more accurate. Because of the need for additional data, a single network cannot categorize all the essential elements in a picture, including bodies of water, roads, trees, buildings, and crops. However, the final network gains some invariance in detecting these classes with environmental changes due to the different geographic positions of roads and buildings discovered in the final datasets, which could be valuable in future navigation research. At the moment, binary classifications of a single class are the only datasets that can be used for the semantic segmentation of aerial images. Even though some pictures have more than one classification, images of roads and buildings were only found in a significant number of samples. Then, the building datasets were pooled to produce a larger dataset and for the constructed models to gain some invariance on image location. Because of the massive disparity in sample size, road datasets needed to be integrated.
时间限制和缺乏精度要求放弃最初的技术。尽管剩余的数据集所识别的类别比最初计划的少,但标签更准确。由于需要额外的数据,单个网络无法对图片中的所有基本元素进行分类,包括水体、道路、树木、建筑物和作物。然而,由于最终数据集中发现的道路和建筑物的地理位置不同,最终网络在检测环境变化的这些类别时获得了一定的不变性,这在未来的导航研究中可能是有价值的。目前,能够用于航空图像语义分割的数据集只有一类的二值分类。尽管有些图片有不止一种分类,但道路和建筑物的图像只在相当数量的样本中被发现。然后,对建筑数据集进行池化,生成更大的数据集,并使构建的模型在图像位置上获得一定的不变性。由于样本量的巨大差异,道路数据集需要整合。

Bantuan Langsung Tunai Dana Desa (BLT-DD), or known as Village Fund Direct Cash Assistance is assistance from the Indonesian government which causes problems and conflicts in the community when the assistance is not on target. The classification algorithm is proven to use in determining BLT-DD recipients. In this study, the radial basis function (RBF) and elman recurrent neural network (ERNN) models compare to classify the eligibility of BLTDD recipients. In the experiment, the optimal performance of the RBF and ERNN compare in determining the eligibility of BLT-DD recipients. Also, it’s compared with the classification algorithm that implements the same data, namely BLT-DD data for Kubu Raya District. The experimental results show the effectiveness of the RBF model in recognizing test data, while the ERNN model is effective in identifying test data. The RBF and ERNN models can achieve the same total accuracy of 98.10%.
