Since the NoSQL database performs better than SQL databases when handling extensive data, many developers choose the NoSQL database as their first choice. Among all the NoSQL databases, HBase has become a popular choice due to its flexibility and high efficiency in the big data processing field. HBase is a column-oriented NoSQL database. It uses HDFS storage and is suitable for integrating with Hadoop ecosystem applications. However, deploying an HBase cluster on bare metal or virtual machines could be pretty complicated and time-consuming. The container technology can make HBase installation more convenient. Nevertheless, containerized HBase can be deployed in different ways. Deploying the HBase cluster in a proper approach can achieve higher performance. In this research, we propose two approaches, namely the Container-dedicated approach and the Container-shared approach, to containerize HBase on Kubernetes. Two benchmark tools are used to compare their performance under different workloads. According to experiment results, the Container-dedicated approach is suitable for writeheavy and read/write balanced applications. The container-shared approach shows a better performance in read-heavy applications. The test result will give future developers a reference when designing a containerized HBase cluster.","PeriodicalId":382440,"journal":{"name":"2022 IEEE International Conference on Recent Advances in Systems Science and Engineering (RASSE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129845288","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}

In order to integrate into human daily life, they should be able to avoid crowd and follow pedestrian flow as human will do. It is not enough to only follow the shortest path for them.The purpose of this work is to implement a navigation algorithm in the real world that considers the flow and density of people. We use a cloud computer to receive fixed camera images, divide regions on the image, and then obtain pedestrian flow and density information through FairMOT[2] algorithm, and wirelessly transmit the information to the unmanned vehicle. Therefore, the unmanned vehicle can avoid high density or reverse flow, and better follow social etiquette.In our implementation, flow directions are with different colors, and shown in our experiments. Furthermore, the flow and density information is passed through WiFi, and affects the cost of a new created cost map layer, called people flow and density layer. The density information affects the navigation reliably. Due to the same area may have different directions of people flow, the following flow algorithm is more challenging.The fixed camera we used is a low-cost webcam, and the unmanned vehicle is with a single camera and a one-line lidar.","PeriodicalId":382440,"journal":{"name":"2022 IEEE International Conference on Recent Advances in Systems Science and Engineering (RASSE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123902801","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}

If oral cancer is diagnosed at an early stage, the overall 5-year survival rate is over 70%, while it drops to less than 40% if detected at a late stage. Thus, early detection of oral cancer is important. Visual non-invasive examination is an efficient and feasible approach for performing a preliminary diagnosis of oral cancer. In this paper, we propose a fully convolutional network (FCN) based model to segment cancer and precancer lesion regions in the oral cavity. In addition to the RGB channels of the input image, we append features of Gabor filter and wavelet filter that show strong response at cancer and precancer regions. We also propose a refine stage before the decision layer of FCN to preventing weight dominating problem when reducing high dimension features to small number of classes.

Facial expression is one of the most natural and universal signals for human beings to convey their emotional states and behavior intentions. Numerous studies have been conducted on automatic human emotion classification that can effectively establish the relationship between facial expression and mental health, while still suffer from intensive computation and low efficiency. Here, we present a memristive circuit design of Sequencer network for human emotion classification, which offers an environmentally friendly approach with low cost and easily deployable hardware. Specifically, a kind of eco-friendly memristor is fabricated using two-dimensional (2D) materials, and the corresponding testing performance is conducted to make sure its efficiency and stability. Then, the memristor-based Sequencer block, as a core component of Sequencer network, consisting of bidirectional long short-term memory (BiLSTM) circuit and some necessary function circuit modules is proposed. Based on this, the memristive Sequencer network can be achieved. Furthermore, the proposed memristive Sequencer network is applied for human emotion classification. The experimental results demonstrate that the proposed circuit has advantages in computational efficiency and cost, comparable to the main existing software-based methods.","PeriodicalId":382440,"journal":{"name":"2022 IEEE International Conference on Recent Advances in Systems Science and Engineering (RASSE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130697881","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}

HD EMG electrodes are composed of a large number of closely spaced channels that simultaneously acquire EMG signals from different parts of the muscle. Given the topological properties of these devices, it is important to fully exploit the spatiotemporal information provided by the electrodes to optimize recognition accuracy. In this work, we introduce the use of Graph Neural Networks (GNNs) to process HD EMG data for movement intention recognition of people with an amputation affecting the upper limbs and which use a robotic prosthesis. In this initial investigation of the approach, we conducted experiments using a real-world dataset consisting of EMG signals collected from 20 volunteers while performing 65 different gestures. We were able to detect 45 gestures with a classification error rate of less than 10%, and obtained an overall classification error rate of 8.75% with a standard deviation of 4.9. To the best of our knowledge, this is the first work in which GNNs are used for processing HD EMG data.","PeriodicalId":382440,"journal":{"name":"2022 IEEE International Conference on Recent Advances in Systems Science and Engineering (RASSE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116260768","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}

In recent years, deep learning techniques have been widely used in the hybrid precoding design to improve spectrum efficiency. This paper proposes an alternating minimization-based deep learning precoding technique for the hybrid precoding. This technique includes the phase information of the channel matrix in the deep learning model to improve the spectral efficiency. In addition, an on-line training method is also designed to track the channel features of the time-varying channel. Thus, the deep-learning neural network model can adaptively track the time-varying channel characteristics with a better performance than its counterpart deep-learning-based hybrid beamforming (DLHB) technique even if the initial network model is not good. The simulation experiments also analyze and compare the spectral efficiency with different hyperparameters of the deep-learning neural network model. The proposed adaptive hybrid precoding technique can further reduce 51.54% of the trainable parameters in the time-invariant environment and 76.14% of trainable parameters can be reduced in the time-varying environment compared to the benchmark technique of the DLHB. With the reduced parameter size, the proposed technique can be 1.6 ms faster than the DLHB with better spectrum efficiency.","PeriodicalId":382440,"journal":{"name":"2022 IEEE International Conference on Recent Advances in Systems Science and Engineering (RASSE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129269313","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 calculate the changes of position and orientation of a camera across successive frames accurately, the corresponding point pairs between two laser point clouds must be identified first, which calls for a time-consuming iterative process. Conventional approaches utilize the laser point cloud data only and do not leverage the information of camera image to expedite the matching process. The proposed scheme analyzes the image first to identify the regions rich of feature points. Compared to flat regions, these regions serve better in point cloud matching. The size of the point could can be largely reduced by pruning out the regions less significant in terms of feature points. This speeds up the process without noticeable compromise of the matching accuracy. We implement the scheme in the odometry estimation module of a Simultaneous Localization and Mapping (SLAM) system and evaluate possible performance enhancement from the proposed scheme. Experimental results show that the enhancement in OE is more significant in a more planar environment. the time saving can be up to 18.9% and the deviation in path trajectory estimation is negligible.","PeriodicalId":382440,"journal":{"name":"2022 IEEE International Conference on Recent Advances in Systems Science and Engineering (RASSE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122089272","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}
