Detection of Megalopa Phase Crab Larvae Using Digital Image Processing 利用数字图像处理技术检测巨斑期蟹幼虫
Novi Nurlaela, M. Niswar, I. Nurtanio, Y. Fujaya, S. Kashihara, Doudou Fall
Blue Swimmer Crab has high economic value as an export commodity. One of the problems that occur in crab culture is cannibalism during the larval development phase. Megalopa phase crab larvae tend to eat zoea phase crab larvae due to inadequate feeding. To avoid cannibalism in the crab larvae development phase, farmers need to check the development of larvae regularly and separate the megalopa phase crab larvae from zoea phase crab larvae. Checking is done by looking directly at the rearing tank, which is time-consuming and difficult because the phase changes in the crab larvae are unpredictable. This research focuses on the detection process of the megalopa phase crab larvae using a convolutional neural network (CNN) method. This research uses 210 images, and detection results get shown an average accuracy of 87.7%.
青蟹作为出口商品具有很高的经济价值。蟹类养殖中出现的一个问题是在幼虫发育阶段同类相食。由于摄食不足,大月相蟹幼虫容易吃小月相蟹幼虫。为避免在蟹幼虫发育阶段同类相食,养殖户需要定期检查蟹幼虫的发育情况,并将大鳞期蟹幼虫与小鳞期蟹幼虫分开。检查是通过直接观察饲养槽来完成的,这既耗时又困难,因为螃蟹幼虫的阶段变化是不可预测的。本文主要研究了卷积神经网络(CNN)方法对巨斑期蟹幼虫的检测过程。本研究使用了210张图像,检测结果显示平均准确率为87.7%。

Smoker’s Melanosis Tongue Identification System using the Spatial and Spectral Characteristic Combinations Tongue in the Visible and Near-Infrared Range 基于可见和近红外波段舌部空间和光谱特征组合的吸烟者黑变病舌部识别系统
Linda Yunita, A. H. Saputro, B. Kiswanjaya
A system that could help a medical practitioner to diagnose a patient who is smoker or nonsmoker is needed. Smoker's melanosis could be used as one indicator to identify someone is a smoker or not. This study focuses on the development of a noninvasive system of smoker identification based on hyperspectral imaging. The developed system consists of a smoker's image acquisition instrument and image processing algorithm using spectral and spatial characteristics in the Visible and Near-Infrared (VNIR) range. The average pixel intensity at a spatial range is used as a feature that represents the relative reflectance at the wavelength of 400 – 1000 nm. The PCA method is used to reduce the dimensions (features) into five characteristic features. The SVM method is used to classify the feature into Smoker's Melanosis (SM) and normal pixel information. This experiment was using 45 samples consisting of 20 smokers and 25 nonsmokers. It was performed to test the performance of the developed system. The results show that the accuracy is 97.31%, misclassification rate (MR) is 2.69%, false-positive rate (FPR) is 0%, false-negative rate (FNR) is 5.83%, sensitivity is 94.17%, and specificity is 100%. In general, the system has worked to help diagnose a smoker.

Design of Optimal Controller for Parallel Hybrid Electric Vehicle Based On Shortest Path Algorithm 基于最短路径算法的并联混合动力汽车最优控制器设计
Pratama Mahadika, Aries Subiantoro
Increasing fuel price has forced automotive manufacturers to innovate in increasing fuel efficiency. Hybrid vehicles, especially Parallel Hybrid Electric Vehicle configuration have been proven to be able to improve fuel efficiency. The main key in term of fuel efficiency of hybrid vehicles is the controller of the Energy Management System (EMS) that manages the performance of the engine and motor so that the vehicle can work in the optimal working range. In this paper, the controller is designed by using shortest path algorithm to find control sequences with the most efficient cost to finish a drive cycle. Because the controller purposed in this paper is using open loop model, then this method can be used as a benchmark to be compared with another method. The result of this study is this method can be used to control EMS of parallel hybrid car efficiently.
不断上涨的燃油价格迫使汽车制造商在提高燃油效率方面进行创新。混合动力汽车,特别是并联混合动力汽车的配置已被证明能够提高燃油效率。混合动力汽车燃油效率的关键是能源管理系统(EMS)的控制器,该系统对发动机和电机的性能进行管理,使车辆在最佳工作范围内工作。本文采用最短路径算法设计控制器,寻找成本最高的控制序列来完成一个驱动周期。由于本文所设计的控制器使用的是开环模型,因此可以将该方法作为基准与另一种方法进行比较。研究结果表明,该方法可以有效地控制并联混合动力汽车的电磁干扰。

Transferring Multi-Channel Convolutional Neural Network Model for Cross-Domain Sentiment Analysis 基于多通道卷积神经网络模型的跨域情感分析
A. Rozie, Andria Arisal, D. Munandar
Analyzing sentiment analysis with deep learning requires massive labeled datasets where such data is not always available. The annotation process is also time-consuming and tedious. Further, even after we train the sentiment analysis, it creates another problem. Because this model is domain-dependent, the performance in another domain estimated to perform poorly. In this paper, we present the transfer learning approach to transfer knowledge gained from the source dataset into the target dataset with the expectation to improve the target model. Multichannel Convolutional Neural Network deploys different n-grams as the input channel in a single CNN model to grasp meaningful features from the text. This method has proven to perform well in sentiment analysis problems. We train our three datasets with different domains using this method as the baseline. The largest dataset then becomes the source model for transfer learning and other datasets as the target. Fine-tuning our source model also needed when retraining it into the target dataset. From the evaluation, we show that several transfer learning strategies outperform the domain-specific model, even when the data is imbalanced. We also highlight certain failing strategies that inflict lousy results on the target model performance.
使用深度学习进行情感分析需要大量标记数据集,而这些数据并不总是可用的。注释过程也很耗时和繁琐。此外,即使在我们训练了情感分析之后,它也会产生另一个问题。因为这个模型是领域相关的,所以在另一个领域的性能估计会很差。在本文中,我们提出了一种迁移学习方法,将从源数据集中获得的知识迁移到目标数据集中,以期改进目标模型。多通道卷积神经网络在单个CNN模型中部署不同的n-gram作为输入通道,从文本中抓取有意义的特征。该方法已被证明在情感分析问题中表现良好。我们使用该方法作为基线,对三个不同域的数据集进行训练。然后最大的数据集成为迁移学习的源模型,其他数据集作为目标。在将源模型重新训练到目标数据集时也需要对其进行微调。从评估中,我们发现即使在数据不平衡的情况下,几种迁移学习策略也优于特定领域模型。我们还强调了某些失败的策略,这些策略会对目标模型的性能造成糟糕的结果。

Determining NPC Behavior in Maze Chase Game using Naïve Bayes Algorithm 利用Naïve贝叶斯算法确定迷宫追逐游戏中NPC的行为
Hidayah Zohro’iyah, S. M. Nasution, Ratna Astuti Nugrahaeni
In this paper, we propose an implementation of Naïve Bayes algorithm in a chase game called Maze Chase. Maze Chase is a chase game where a player must avoid several chasings Non-Player Character (NPC). In our proposed implementation, the NPC will run automatically using artificial intelligence. There are four NPC in Maze Chase, each with its own characteristics. Because of the characteristic differences, the four NPC needs to communicate with each other. For communication we use a multi-agent system. Multi-agent system is a part of artificial intelligence which were used by NPC to communicate with each other using several defined parameters. We used several parameters, such as the number of coins in a zone, the amount of golden coins in a zone, and the centroid values. These parameters were used as variables for an implementation of Naïve Bayes algorithms. Our proposed implementation of Naïve Bayes was used to count the probabilities of NPC behavior, which will move closer towards the player according to several zones in the game map. From the testing results, Naïve Bayes algorithm could be used to decide the NPC movement according to its target zone on the Maze Chase game, with error rate 0.5%.
在本文中,我们提出了一个Naïve贝叶斯算法在一个名为迷宫追逐的追逐游戏中的实现。《Maze Chase》是一款追逐游戏,玩家必须避开几个非玩家角色(NPC)的追逐。在我们提议的实现中,NPC将使用人工智能自动运行。在《Maze Chase》中有4个NPC,每个都有自己的特点。由于各自的特点不同,这四个NPC之间需要相互沟通。对于通信,我们使用多智能体系统。多智能体系统是人工智能的一个组成部分,它是由NPC使用几个定义好的参数来相互通信的。我们使用了几个参数,例如区域中的硬币数量,区域中的金币数量以及质心值。这些参数被用作实现Naïve贝叶斯算法的变量。我们提议的Naïve贝叶斯实现用于计算NPC行为的概率,NPC将根据游戏地图中的几个区域向玩家靠近。从测试结果来看,Naïve贝叶斯算法可以根据迷宫追逐游戏中NPC的目标区域来决定NPC的移动,错误率为0.5%。

3D Model of Photogrammetry Technique for Transtibial Prosthetic Socket Design Development 三维摄影测量技术在胫骨假体窝设计中的应用
R. B. Taqriban, R. Ismail, M. Ariyanto, Andika Febri Yaya Syah Putra
This paper presents the development of the manufacture of a transtibial prosthetics socket for the below-knee amputee. A technique used in this paper is using photogrammetry. The quality of the photogrammetry method is determined by measuring the error of the photogrammetry 3D model with the actual model using four different cameras. The 3D model of the transtibial socket is created by taking photos of the remaining limb of the amputee and process it in the software for the 3D generation and rectification process. 3D printing is needed to print the 3D model of the socket and then compare it to the conventional casting socket using image processing. The test will be conducted by applying the 3D printed socket to the amputee to be used for a walk.

The test will be conducted by applying the 3D printed socket to the amputee to be used for a walk.","PeriodicalId":367363,"journal":{"name":"2019 International Seminar on Research of Information Technology and Intelligent Systems (ISRITI)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128978914","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}

Selecting Palm Oil Cultivation Land using ARAS Method 利用ARAS法选择棕榈油种植用地
Muhammad Ari Prayogo, Jatmiko Endro Suseno, Dinar Mutiara Kusumo Nugraheni
The importance of selecting alternative land used for palm oil cultivation requires some priority assessment of the land, therefore the need to implement a decision support system in choosing which land to plant palm oil in the future. There is no system for selecting land priority to plant palm oil purpose of this study is to develop a system for selecting palm oil cultivation land by implementing a decision support system using the Additive Ratio Assessment (ARAS) method in analyzing each alternative land criteria. The results showed that the alternative lands ranking that had the highest value AL3, which was Mendik Makmur, had the highest K value of 0.869, which placed the land Mendik Makmur in the first rank based on ARAS method calculations. The resulting accuracy testing ARAS method by comparing the ranking results with other methods against the results of expert assessments get an accuracy score of 77%, with 7 alternative ranking positions are the same as the results of the assessment of experts from a total of 9 alternatives.
选择用于棕榈油种植的替代土地的重要性要求对土地进行一些优先评估,因此需要在未来选择种植棕榈油的土地时实施决策支持系统。目前尚无选择土地优先种植棕榈油的系统,本研究的目的是通过在分析每个备选土地标准时使用加性比率评估(ARAS)方法实施决策支持系统,开发棕榈油种植土地选择系统。结果表明:AL3值最高的备选土地排名为门迪克·Makmur, K值最高,为0.869,根据ARAS方法计算,门迪克·Makmur土地居首位;所得到的准确性测试ARAS方法通过将排名结果与其他方法的专家评估结果进行比较,得到准确率分数为77%,其中7个备选排名位置与9个备选专家的评估结果相同。
