After a prolonged use of a faulty bearing, cracks are created on more than one parts of the bearing, which is a compound fault condition. This situation is tougher than the single fault condition. This combined faulty bearing creates a complex vibration signal with significant amount of noise, where it becomes very difficult to identify the fault frequencies by signal processing methods. This paper deals with a novel machine learning method for the compound fault diagnosis of Rolling bearing, where compound fault signals are decomposed into Intrinsic Mode Functions (IMF) by Ensemble Empirical Mode Decomposition (EEMD). The proposed method uses Convolution NeuralNetwork (CNN) based technique, which receives the decomposed signals of compound fault signal as input to CNN. These IMFs consists of groups of different frequencies. When these IMFs are given as input to CNN it classifies it effectively into different faults existing on bearing. CNN yields almost 96% accuracy which is better than any other previous performance for compound faultclassification.

Usability is the level of ease of users in using the interface on a system. Usability can be measured using expert judgment or user testing. One of the techniques in usability measurement that can be is Heuristic Evaluation (measured by the expert) and Usability Metric for User Experience or as known as UMUX (measured by user). Heuristic Evaluation is an interface evaluation process that aims to measure an interface's usability, efficiency, and effectiveness based on ten heuristic rules. Meanwhile, UMUX is a short-level instrument method or rating level used to collect quantitative user data about the usability of an application. Therefore, the combination of expert judgment and user assessment will provide rich and complementary findings. In this study, we used “CARDS” as the research object. “CARDS” is a digital card application or e-wallet used to pay bills, top-up card balances, online stores, and Payment Point Online Banks. This study aims to improve the quality of service to users of the “CARDS” application by testing the user experience. The result shows that the UMUX score is not equal to 74, so it is necessary to make improvements, with recommendations from experts by the Heuristic Evaluation method based on the lowest assessment score, namely the Consistency and Standards category.

This research aims to study the suitable time series analysis to forecast the automobile and parts product export values over the next 12 months. The time series data source gathers from the Government Open Data of Thailand official website during January 2013 to December 2021, 108 months in total. The experiment starts with creation, comparison, selection, verification, and forecasting. Time series analysis has considered five methods: Trend Analysis, Moving Average, Decomposition, Single Exponential Smoothing, and Double Exponential Smoothing. We use mean absolute present error (MAPE), mean absolute deviation (MAD), and mean squared deviation (MSD) to compare and select the least value. The result showed that Moving Average had the best performance. Then we used the Moving Average to verify and forecast over the next 12 months. However, it was found that the forecast values obtained were constant for the entire 12 months, so the moving average is unused for forecasting. The Moving Average has the least mean absolute present error (MAPE) at 0.2420. Therefore, we have used Decomposition which is a suitable performance in the second order of forecasting. It is forecast and has a trend value. Moreover, the Decomposition method has the least mean absolute present error (MAPE) at 0.1832.
本研究旨在研究适合的时间序列分析，以预测未来12个月的汽车及零部件产品出口价值。时间序列数据源来自泰国官方网站Government Open data，时间为2013年1月至2021年12月，共108个月。实验从创造、比较、选择、验证和预测开始。时间序列分析考虑了五种方法:趋势分析、移动平均、分解、单指数平滑和双指数平滑。我们使用平均绝对当前误差(MAPE)，平均绝对偏差(MAD)和均方偏差(MSD)来比较和选择最小值。结果表明，移动平均线的表现最好。然后我们使用移动平均线来验证和预测未来12个月的走势。然而，我们发现，整个12个月的预测值是不变的，所以移动平均线不用于预测。移动平均线的平均绝对当前误差(MAPE)最小，为0.2420。因此，我们使用了分解，这是一种适合于二级预测的性能。它是预测的，具有趋势值。此外，分解方法的平均绝对当前误差(MAPE)最小，为0.1832。

A number of patients with untreated caries only seek treatment at late stages when serious complications might have already developed and can lead to significant acute and chronic conditions with high cost of treatment. The purpose of this research is to be able to find out the level of caries based on X ray images by using image processing and machine learning methods. The image processing algorithm namely Gray Level Co-occurrence Matrix (GLCM) has been used to extract texture features and Multilayer Perceptron (MLP) methods to classify the X ray caries images. Lavenberg Marquard and Backpropagation Bayesian Regularization are used in this study. The conclusion obtained in this study is that the algorithm of classification using Multilayer Perceptron (MLP) based texture features can classify dental caries images in four classes. The best performance result is achieved the training accuracy of 99.20% and the testing accuracy of 98.30% by using Lavenberg Marquardt (LM) model with hidden layer 10. In Backpropagation Bayesian Regularization (BR), the best results are found in hidden layer 10 as well (Training: 100%, Testing: 100%).

Swallow Nest is a valuable export commodity, particularly in Indonesia. It is produced when a swallow's saliva hardens and is frequently encountered in high-rise buildings. Swallow nests can be utilized to treat various ailments in the medical sector. The price of a swallow nest varies according to its quality, which is commonly classified into three grades: quality 1 (Q1), quality 2 (Q2), and quality 3 (Q3). Q1 is of the highest quality, while Q3 is of the lowest. Each grade has a different physical appearance. Currently, many people lack knowledge regarding the grade of a swallow nest. Therefore, a method is needed to automatically classify the quality of swallow nests based on computer vision. The proposed method consists of several main processes, including image acquisition, ROI detection, pre-processing, segmentation, feature extraction, and classification. The feature extraction was applied based on shapes, followed by the Support Vector Machine (SVM) implementation in the classification process. This process was performed with cross-validation using the k-fold values of 5. The performance evaluation was done using three parameters: precision, recall, and accuracy, by achieving the value of 90.6%, 89.3%, and 89.3%, respectively.

During COVID19 pandemic, people are encouraged to practice physical distancing at least 1 meter when interacting with other people to prevent the spread of the COVID19. This study aims to develop a system that can monitor the physical distancing and track physical contact in a room using internet of things (IoT) and artificial intelligent technology. The system consists of a small single-board computer (Raspberry Pi), webcam, and web application displaying physical contact information. The system uses YOLO algorithms to detect the human object and euclidean distance formula to determine the distance between human objects. We evaluated the performance of YOLOv3 and YOLOv3-tiny running on Raspberry Pi. The evaluation result shows that YOLOv3 consumes more CPU resources than YOLOv3-tiny but has better accuracy in detecting human objects. YOLOv3-tiny can process images and detect objects faster than YOLOv3.

Sinovi (Innovation Center Innovation System) is a website developed to manage the collection of innovation and HAKI owned by the ITTP academic community. Based on the results of initial observations made by interviewing the Center for Innovation and HAKI, although it has been done twice socialization of website use, there are still complaints and obstacles experienced by users. Based on these problems, the researchers conducted research on evaluating the user experience (UX) of the Sinovi website. This study aims to determine the system's performance based on user experience. The UX evaluation process uses methods moderated remote usability testing and user experience questionnaire (UEQ). The study's results using moderated usability testing showed a significant difference in completion rate between the two groups of users, with each group having values of 0.9560 and 0.8235. While the results of time-based efficiency tests showed that the average time-based efficiency between group A and group B has similarities with the values obtained, respectively are 0.1652 and 0.1259. The test results using UEQ show that the Sinovi website has managed to get a positive evaluation. Several categories were successfully obtained, including the “Attractiveness” category with a score of 1.967, the “Perspicuity” category with a score of 1.850, the “Efficiency” category with a score of 2.042, the “Dependability” category with a score of 1.825, and the “Stimulation” category with a score of 1,742. The overall user experience evaluation results show that Sinovi's website is already at a good user experience level but needs to improve to reduce the number of problems.

A web-based online complaint portal is one of the e-government public services. The complaint's content must be categorised in order for it to be transmitted to the appropriate agency swiftly and properly. The most often used standard classification algorithms are the Naive Bayes Classifier (NBC) and k-Nearest Neighbor (k-NN), both of which classify just one label and must be tuned. The purpose of this project is to categorize complaint messages that include several labels simultaneously using NBC tuned for particle swarm optimization (PSO). The data source is the Open Data Jakarta and is partitioned into 70% training data and 30% test data for classification into seven labels. The NBC and k-NN algorithms are used to compare PSO's optimization performance. Cross-validation ten times revealed that optimizing NBC with PSO obtained an accuracy of 88.16%, much superior than k-NN at 83% and NBC at 70.57%. This optimization approach may be used to improve the efficacy of community-based e-government services.
基于网络的网上投诉门户是电子政务公共服务的一种。投诉的内容必须分类，以便迅速和适当地转交给适当的机构。最常用的标准分类算法是朴素贝叶斯分类器(NBC)和k-最近邻分类器(k-NN)，这两种算法都只分类一个标签，并且必须进行调优。本项目的目的是对同时包含多个标签的投诉消息进行分类，使用针对粒子群优化(PSO)进行调优的NBC。数据源为Open data Jakarta，将其划分为70%的训练数据和30%的测试数据，分类为7个标签。用NBC算法和k-NN算法比较了粒子群算法的优化性能。10次交叉验证表明，PSO优化NBC的准确率为88.16%，明显优于k-NN的83%和NBC的70.57%。这种优化方法可用于提高基于社区的电子政务服务的效率。

The complaint's content must be categorised in order for it to be transmitted to the appropriate agency swiftly and properly. The most often used standard classification algorithms are the Naive Bayes Classifier (NBC) and k-Nearest Neighbor (k-NN), both of which classify just one label and must be tuned. The purpose of this project is to categorize complaint messages that include several labels simultaneously using NBC tuned for particle swarm optimization (PSO). The data source is the Open Data Jakarta and is partitioned into 70% training data and 30% test data for classification into seven labels. The NBC and k-NN algorithms are used to compare PSO's optimization performance. Cross-validation ten times revealed that optimizing NBC with PSO obtained an accuracy of 88.16%, much superior than k-NN at 83% and NBC at 70.57%. This optimization approach may be used to improve the efficacy of community-based e-government services.","PeriodicalId":178279,"journal":{"name":"2022 IEEE International Conference on Cybernetics and Computational Intelligence (CyberneticsCom)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124910319","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}

To enhance sustainable food security, the cost-efficient data collection technology for estimating rice production in a major agriculture nation such as Indonesia is undoubtedly vital to support the existing official data collection. The current official data collection is still facing great challenges in terms of its high cost and laborious nature. This study aims to build machine learning-based models for rice production estimation by utilizing multitemporal Normalized Difference Vegetation Index (NDVI) data obtained from Landsat-8 remote sensing satellite imagery focusing on Ngawi Regency, East Java, Indonesia as a case study area. Our investigation reveals the quarterly changes in vegetation conditions of the rice fields can be captured through the NDVI value. Four different machine learning models are constructed and evaluated to process the satellite data. Support vector regression (SVR) was shown to obtain the best performance from 10-folds cross-validation with the average root mean square error (RMSE) of 6952.89 tons and has a quite high coefficient of determination (R2) score which is up to 0.9. The current estimation results provide an incentive to use satellite imagery data and machine learning models to support agricultural monitoring and decision-making.
