The ratio between the number of cancer training thermograms and the normal training thermograms corresponding to first CNN module is denoted by β. The corresponding ratio for the second CNN module is chosen to be (1/β). The influence of the asymmetry training parameter β over the decision fusion classifier performances is evaluated.

Previous studies have primarily focused on conducting sentiment classification and emotion classification as separate tasks. Only a limited number of researchers have delved into exploring the relationship between these two and invested efforts in deriving one from the other. This study aims to determine sentiment by employing emotion classifications. Specifically, we utilise the ERNIE Tiny deep learning model to classify emotions in Chinese texts, and detect sentiments through our devised rules. For instance, if emotions such as ‘happiness' or ‘like’ are present, the sentiment is classified as positive. Conversely, emotions like ‘sadness', ‘disgust’, ‘anger’, or ‘fear’ classify the sentiment as negative. The experimental results demonstrate the F1 score of 93.00% and 90.14% for positive and negative sentiment, respectively, in Chinese song reviews.

This method requires time and human-resources depending on the scale of the greenhouses. However, the measured data are sometimes inaccurate and leads to wrong activities, such as irrigation, which may make negative effects on plants, soils and increase unnecessary resource expenses. Fortunately, in the recent years, different modern technologies have been applied to agricultural sphere and implemented smart monitoring, smart irrigation and other hi-tech systems. However, it is still a major challenge to achieve better energy efficiency and reduce the cost of monitoring real-time parameters in high quality. In this research work, we developed and implemented a wireless sensor network (WSN) based monitoring system for specifically greenhouses and focused on solving the two main issues: longer life-longevity of WSN devices and lower the system cost. In order to achieve the longer life-longevity of wireless devices we developed specific WSN devices consisting of the most low-power consuming electronic components. Besides, an operational algorithm and measurement method has been developed. On the purpose of decreasing the hardware material costs, we did choose the most optimal priced electronic components. WSN sensor nodes make measurements of four parameters, soil moisture level, soil temperature, air humidity and temperature. The measured data is sent to coordinator node which forwards each received data packets to web platform of the system. Gardeners can monitor the real time agricultural parameters of their greenhouses with 5% maximum error through the web platform on any point of the earth where internet connection is available.","PeriodicalId":391483,"journal":{"name":"2023 15th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133845388","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}

Solutions like software-defined networking (SDN), and network function virtualization (NFV) are proposed with 6G, but the core management operations are still manual. Thus, to automatically upscale these 6G-IoT networks at reduced cost orchestration complexity, zero-touch networks (ZTN) are proposed. ZTN in 6G-IoT allows a high degree of automation and seamless integration of services. The article proposes a scheme, Zero-Load, that integrates ZTN at the core routing functionality of the 6G-IoT applications. We present a load balancing and traffic classification scheme through the ZTN networking stack for core routers. The ZTN router configuration fabric connects applications with the core services. Further, we present a Gaussian kernel-based support vector machine (SVM) classifier at the ZTN automation layer, which classifies the normal traffic and attack traffic. The proposed work is compared for parameters like mean time to response (MTTR), and resolution latency against baseline SDN and NFV schemes. Using ZTN, an average improvement of 32.45% is obtained in MTTR, and 87.89% in resolution latency (against a query). Using the Gaussian RBF kernel, an accuracy of 0.9914 is reported. These results indicate that ZTN-based management paves the way toward a more dense and intelligent 6G-IoT network.","PeriodicalId":391483,"journal":{"name":"2023 15th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114781307","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}

Instead of predicting PM10 values for the entire dataset, better results were obtained when forecasting air pollution values for each discovered cluster. In the clustering stage, the k-means algorithm was applied, and four clusters were discovered. It could be noticed that two clusters corresponded to normal PM10 values, having the centroid values equal to 16, respectively 1, and the other two clusters stored high rates of pollution (with centroid values equal to 53, respectively 34). The forecasting results were more accurate when learning a cluster at a time with a specific classifier. After this step, several forecasting models were applied for each obtained cluster, and a conclusion that K-Nearest Neighbors and Neural Networks models had best performance in predicting the PM10 values is finally made.","PeriodicalId":391483,"journal":{"name":"2023 15th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115779388","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}
