First, we trained the DNN prediction model using data from 2015 to 2020, and then evaluated it using data from 2021. Next, we performed LRP on the evaluation data to analyze the importance of input factors in the prediction results. As a result, factors with consistently high importance regardless of concentration were O_TA, O_TD, O_RH, O_U, O_V, and O_PA, whereas PMSUB10/SUB and O_RN_ACC were observed to have lower importance. Furthermore, to analyze the characteristics of high-concentration data that are generally difficult to predict compared to low-concentration data, we divided the data by concentration and analyzed the importance of input factors. As a result, the importance of O_PMSUB2.5/SUB was high in the high concentration pattern and the importance of O_radiation was low, while the opposite trend was observed in the low concentration pattern. In particular, for high-concentration patterns that started suddenly and lasted more than three days, we analyzed the importance of input factors by time and factor. These high-concentration patterns with these characteristics showed significantly increased importance in the O_PMSUB2.5/SUB factor in the T12 interval closest to the prediction time, and it was observed that the importance of the F_PMSUB2.5/SUB factor increased slightly. Applying the factor importance results analyzed in this study to the PMSUB2.5/SUB prediction model is expected to improve prediction accuracy for high concentration patterns that are difficult to predict compared to general patterns.","PeriodicalId":16316,"journal":{"name":"Journal of Korea Multimedia Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135991533","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 minimize the occurrence of diseases, it is crucial to administer an appropriate amount of feed and manage breeding diligently while mitigating any stress factors affecting the fish. This study involves the development of a fish species and disease detection system, where models are trained to identify different types of fish and their diseases. The system is designed to be used by fish farmers, offering a user-friendly interface through the Web. In the model training, the YOLOv7 model demonstrated high performance, achieving over 0.9 accuracy in detecting fish species. Meanwhile, for fish disease detection, the YOLOv5l model exhibited overall superior performance. However, there was a limitation in the dataset for fish disease detection, with only a small number of samples available. To overcome this, the fish species and disease detection system, developed in conjunction with the YOLOv5l model, was incorporated into the web page. This system aims to help identify the species, disease status, and specific affected regions in the fish population.","PeriodicalId":16316,"journal":{"name":"Journal of Korea Multimedia Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135991670","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}

Conversational digital humans can be categorized into avatar and agent. This paper introduces the Hybrid Avatar Agent System (HAAS), designed to implement a conversational digital human capable of addressing diverse questions. To facilitate seamless transitions between avatars and agents, we developed a Korean Dialogue Breakdown Detection (DBD) model. While a digital human typically functions as an agent, the DBD model identifies conversational pauses, prompting human operator intervention for user assistance. We trained DBD model using the RoBERTa_base model, achieving an accuracy of 60.77%. In a user study, a comparison was drawn between HAAS and the Agent Only System (AOS). Users noted that HAAS provided more appropriate answers than AOS.","PeriodicalId":16316,"journal":{"name":"Journal of Korea Multimedia Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135991694","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}
