Abstract

Gallery art websites are often used to display artistic work for user accessibility. The conventional web-based gallery is built on the hyper-text Markup Language (HTML) which is limited in terms of content dynamism, interactivity, and scalability. GANs provide advanced capabilities with continuously evolving art experiences, making them a powerful tool for modern digital art galleries. Artistic websites have significantly contributed to the exhibition of artistic images since they can be accessed anywhere. However, the artistic web suffers from being too passive and lacks in-depth interactivity to keep people meaningfully engaged with an exhibition virtually. This paper explores the exhibition of 3D images within a virtual art gallery using an intelligent artistic web-based applications framework that integrates Variational Autoencoder and 3-D Signed Distance Function Cycle GAN (VAE-3DSDFCycleGAN) and quantitative questionnaire methods. The virtual gallery utilises GAN architectures to produce diverse and original 3D artworks, addressing traditional art galleries' spatial, viewing dimensions, image quality, and accessibility limitations. The questionnaire was used to evaluate the user’s satisfaction. The experiment was done on the Coco African Mask dataset to generate 3-D images, yielding a high result and satisfaction in terms of the ease of use and viewing of the artistic image contents.

Abstract

The rapid expansion of digital transactions in Indonesia is driving the transformation of both traditional and digital banks. Since digital banks operate without physical branches, all banking services are via mobile banking apps. This study examines mobile banking service quality using text mining techniques like topic modeling and term ranking to analyze 11,815 user reviews from app stores and assess customer satisfaction through ratings. The research involves extracting and preprocessing reviews, identifying key topics, and linking them to satisfaction levels. Seven service dimensions were found: customers were satisfied with Enjoyment, Debit Card Delivery, and Feature-Free Transactions but dissatisfied with Accessibility, Data Privacy, Loan Services, and Touchless Customer Support. Debit Card Delivery and Feature-Free Transactions were highlighted as significant factors in Indonesia's digital banking market. With limitations in analyzing user reviews in Bahasa Indonesia, the findings are specific to the Indonesian digital banking context and may not be applicable elsewhere.

Abstract

Nutrition is a human's physical condition resulting from the balance of energy supplied and then released by the body. Nutrition is important to support the growth and development of babies. The period of toddlerhood is a very important period, because if the nutritional status of young children is inadequate then complications can arise in their health. The system used to determine children's nutrition is the K-nearest neighbor (KNN) method. This technique is a way to classify or group several test data whose classes are not yet known. This system uses variables based on anthropometric data or the baby's body sequence, namely childhood, child's weight, height and child's condition. The algorithm used in this research is K-NN in the child nutritional status classification system which determines whether the child's status is normal or not. The system development method used is Waterfall. According to the results of accuracy measurements, the success rate for determining the nutritional status of toddlers using this system was 79.17%
