These transformations included factors such as students' gender, age range, and parental education level. Subsequently, the Biogeography-Based Optimization (BBO) algorithm was utilized to determine the most important 20 features, which were then incorporated into machine learning models. During the evaluation phase, metrics such as Accuracy, Precision, Recall, and F1 score were employed to obtain results. The highest Accuracy value, 0.7388, was achieved with the Gradient Boosting algorithm. To elucidate the success of this algorithm, interpretable artificial intelligence models such as SHAP and LIME methods were employed. The findings of the study underscored the importance of detailed examination of factors influencing student success, emphasizing the need for further research to formulate education policies more effectively. The results of this study may contribute to the enhancement of data-driven decision-making processes in education and the more effective planning of interventions aimed at improving student success.","PeriodicalId":397495,"journal":{"name":"Journal of Smart Systems Research","volume":"4 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141267415","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}

It is important for the future of our country and the world that these wastes are more easily identified and recycled. In the process of recycling wastes, the classification of wastes as well as their collection requires costly energy and manpower. Wastes are basically separated into paper, plastic, glass and metal. Various studies have been carried out to complete these processes in a shorter and easier way with technologies such as artificial intelligence, deep learning and image processing. In this study, a dataset of paper, plastic and food and beverage wastes that are common in the environment was created. In this dataset, paper cups, plastic water bottles and fast food wastes were detected from different locations in nature and photographed. These images were labeled and trained and tested with YoloV3 in deep learning algorithms. In addition, in order to compare the performance of the new dataset, studies were conducted on a global dataset used in the literature. As a result of the studies, it was observed that it was successful in classifying the newly created dataset and the global dataset.","PeriodicalId":397495,"journal":{"name":"Journal of Smart Systems Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138587563","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}

Processes for delivery and return need to be more adaptable and effective in this situation. Smart outdoor cargo vending systems have been created to satisfy this need. These systems do, however, have some drawbacks, such as security and energy usage. In order to address the issues with outdoor vending, this paper presents an indoor smart cargo vending system with high security and minimal energy consumption. Customers have the choice to pick up or return their orders with the help of this system. Additionally, this creative solution aids e-commerce businesses in decreasing logistics expenses and raising customer satisfaction. For manufacturers of vending machines and e-commerce businesses, this proposed indoor smart cargo vending system provides solutions for all scenarios of cargo order processes. This solution combines the design of the system's hardware and software with a methodology that has been discussed in the scientific literature. The study's conclusion suggests a novel indoor smart cargo vending system that was created in response to the logistical difficulties brought on by the expansion of e-commerce. This system can have a positive impact in key areas like security, energy efficiency, and customer satisfaction, and it can be seen as a significant advancement for the logistics sector.","PeriodicalId":397495,"journal":{"name":"Journal of Smart Systems Research","volume":"18 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138603081","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 this study, the proposed system is used for secret and vital places that need a good monitoring system based on human motion detection. The system can protect museums that contain critical historical objects and libraries with old historical books. The security alert system is also essential to the protection of banks. The system uses a two-frame difference algorithm and a simple background modeling algorithm for motion detection with the help of AForge.NET. Whenever the system detects motion, it interprets the frames of motion to determine humans by using YOLO. The security alert system activates the alerts whenever it detects human motion, like sending an email to an authorized person, triggering the LED alert and sound alert, recording a video of that place, taking a motion picture, and saving it within the databases. The system has the advantages of low cost, a user-friendly interface, and high security. The system was thoroughly tested to detect human movement in unauthorized areas. The system successfully detected human activity indoors and outdoors and activated the alarms. Also, the system could detect human movement in all four directions and alert observers directly at the time of the incident. In low light or minimum illumination, the system can determine human motion. The evaluation results showed that the system's accuracy in detecting human movement was 95%, which shows that the system is able to protect vital and secret places and can successfully monitor areas.","PeriodicalId":397495,"journal":{"name":"Journal of Smart Systems Research","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131824715","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}
