Leveraging the power of computational methods, AI can perform effective strategies in intelligent design. Researchers are pushing the boundaries of AI, developing computational systems to solve complex questions. The authors investigate the association of user preference for UI and deep image features, aiming to predict user preference level using deep convolutional neural networks (DCNNs) trained on a UI design image dataset. A total of 12,186 UI design images were collected from UI.cn and DOOOOR.com. Users' views and likes can help understand the implicit user preference level, which is set as the ground-truth annotation for the dataset. Six DCNNs, including VGG-19, InceptionNet-V3, MobileNet, EfficientNet, ResNet-50 and NASNetLarge were trained to learn the user preference of UI images. The experiment achieves an optimal result with a mean-squared error of 0.000214 and a mean absolute error of 0.0103 based on Effi-cientNet, which indicates that the proposed method provides the possibility in learning the pattern of user aesthetics preference for UI design. On the basis of the prediction model, a mobile application named 'HotUI' was developed for UI design recommendations.

Have you ever woken up refreshed after only 4 hours sleep, and woken up listless after 8 hours sleep? Many works of literature reviewed how sleep deprivation affects people in many ways. While there has been much research on the problem of sleep deprivation, few researchers have considered sleep stage duration. In this study, we focus on the sleep stage instead, to find out whether a specific sleep duration affects people's attention span.
