DRL framework uses Proximal Policy Optimization algorithm to dynamically learn the UHD in an emulated 3D UAV mobility environment to manage the handover decisions.

Class imbalance is a condition where the number of classes in the dataset used in the classification process has a significant difference in number. In theory, most single classifiers have a weakness against class imbalance conditions in datasets, especially those with multiclass types, so their performance cannot be maximized. This study proposes two approaches to overcome the problem of multiclass imbalanced, namely the use of ADASYN (Adaptive Synthetic) Sampling and the Stacking Algorithm. As confirmed by testing on five multiclass datasets, the proposed method outperforms other methods in terms of accuracy values, sensitivity, specificity, and geometric mean values. As a result, the method proposed in this study can solve class imbalance problems in multiclass-type datasets. However, this study has limitations. Namely, the dataset used is a multiclass category with a maximum number of six classes. For this reason, further research will suggest testing using imbalanced class datasets in the category of multiclass datasets with more than six classes.","PeriodicalId":367038,"journal":{"name":"2022 16th International Conference on Ubiquitous Information Management and Communication (IMCOM)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114739121","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}

This creates self-doubt, self-image problems, difficulty in managing emotions and behavior, as well as leads to unstable relationships. But this disorder can be cured with proper treatment if diagnosed early. The aim of this research is to explore potential features in the detection of Borderline Personality Disorder using machine learning methods. Furthermore, it identifies the potential features(here emotions) which are responsible in the detection of Borderline Personality Disorder. Data were collected in two ways one from self declared user in social media(i.e. who declared themselves as Borderline Personality Disorder patients) and second by inviting people for a Borderline Personality Disorder screening test Permission has been taken to fetch their social media data for research. This research achieved an accuracy of 81.03% using Random Forest classification algorithm. Emotional features were extracted from each data point in the dataset to identify the potential features for Borderline Personality Disorder classification. Features such as nervousness, shame, and pain have been derived that can in turn contribute to a similar accuracy to about 81.25%. This attempt is to explain the heuristic explanation, how differently an individual with Borderline Personality Disorder reacts from other individuals.

The main advantages of the proposed method are that it improves speed control of the motor when parameter uncertainties and external load torque exist in the speed loop as an unknown disturbance. First, a sliding mode control method based on an adaptive sliding mode reaching law (ASMRL) is proposed to improve sliding mode chattering. Then, considering the influence of the unknown disturbance in the speed control, the reduced-order PI observer is employed to estimate the disturbance and feed it forward to the ASMRL as a compensation signal. Therefore, the robustness of the ASMRL will be maintained under the combination of ASMRL+ROPIO. The results in practical experiments show the effectiveness of the ASMRL+ROPIO method for reducing chattering and dealing with unknown disturbances.","PeriodicalId":367038,"journal":{"name":"2022 16th International Conference on Ubiquitous Information Management and Communication (IMCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130325097","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 general, radiologists manually handle this procedure, but manual analysis performed by individual poses a problem of consistency depending on the experts. One of the standardized alternatives was to apply automated deep learning method in this field. In fact, majority ideas in literature are dominantly based on the supervised learning framework, but even such methods have still failed to present promising discrimination performance. In this work, we assume that unsupervised learning still can be a potential option and beneficial attribute that enables to accelerate discrimination is inherent in it. Hence, we present a deep representation for the ultrasound breast data utilizing two types of independent supervised and unsupervised network to reconstruct the principal features, while the volume of supervised features is set to be minimum and the volume of unsupervised is the maximum. Specifically, we adopted pretrained Resnet34 as a supervised network, and a convolutional autoencoder (CAE) was designed for the unsupervised network. Each representation vector is combined into a single vector, and the generated vector is given to the support vector machine as an input for the final discrimination. The results are verified that the proposed method shows far better performance compared to several conventional deep learning methods and the single use of each method. The value of accuracy, sensitivity and specificity are obtained by 88.18%, 85.25% and 100.00% respectively.","PeriodicalId":367038,"journal":{"name":"2022 16th International Conference on Ubiquitous Information Management and Communication (IMCOM)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132247827","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}

The IEEE AVB Ethernet standard includes protocols to synchronize time, set up standards for stream reservation, and schedule standards for forwarding and queuing, among others. However, AVB is difficult to apply to industrial networks such as industrial automation and automobiles due to lack of consideration for control data that must ensure transmission time. To solve this issue, IEEE proposes the 802.1 time-sensitive network standard, and various studies are being conducted with regard to related applications. In this study, based on the structure of the existing IEEE 802.1Qav protocol, the time-determined forwarding and queuing functions designed using the time-aware shaper, priority queuing, and credit-based shaper algorithms are described. TC275 (Infineon) was used for functional implementation, and VN5620 (Vector) was used for data monitoring.
