In the context of globalization and digitalization, there are both opportunities and challenges for integrating ethnic patterns into packaging design, and traditional methods are inefficient and poor in creative integration due to the lack of advanced algorithms. In this study, the EfficientNet image recognition and transfer learning algorithms were used to construct a new packaging design system, and the accuracy of ethnic pattern recognition on a large-scale dataset exceeded 95%, far exceeding that of traditional algorithms. The system analyzes design needs, selects fusion patterns, and generates packaging designs with a modern aesthetic. Through transferlearning to achieve cross-cultural design innovation, the experimental display system can improve design efficiency by 30% while maintaining design innovation and cultural depth, effectively shortening the design cycle. This shows that the intelligent design system based on EfficientNet significantly improves the application effect of ethnic pattern packaging design, high recognition accuracy ensures accurate pattern application, cross-cultural innovation gives packaging culture inclusiveness, and efficiency improvement strongly supports the application of ethnic patterns in the field of modern design, promotes the development of national culture communication, and explores more technology integration in the future to continuously optimize system performance.

Processing large and complex parts requires various tools, a number of which need to be replaced during the process. However, the variable dynamic characteristics of different cutting tools can significantly affect the accuracy of cutting force modeling and prediction. A data-driven approach utilizing neural networks and transferlearning is proposed for predicting milling forces across various tools. Initially, cutting data from milling experiments using different tools and machining parameters are collected to form a dataset. The source tool contains a comprehensive set of process parameters data, whereas the target tool includes a small number of labeled and test groups. Afterwards, the input data of the source and target tools are fed into an autoencoder with a maximum mean discrepancy loss function to reduce the marginal distribution discrepancy. Furthermore, affine transformation is performed to generate pseudo-labels, thereby augmenting the dataset and providing coarse data for the target tool. Finally, the TrAdaBoost.R2 algorithm is applied to establish the cutting force prediction model specific to the target tool. The training set of which includes a combination of pseudo-data and a small amount of target tool marked data, enabling accurate prediction of the cutting forces for the target tool's unlabeled data. Detailed experimental validation is performed on five-axis machine tools to verify the accuracy and effectiveness of the designed methodology. Comparison results show that prediction accuracy improved by more than 50%, 35%, and 65% compared with network trained directly with source domain data, models trained directly with TrAdaBoost.R2 algorithm, and network trained with small amounts of data from the target tool, respectively, which showcase the superiority of the proposed model.
The simulation data is complete, but the measured data is unbalanced or missing, which makes it difficult to apply the data-driven model. In addition, there are many adjustable hyperparameters and artificially adjuste...

Phytotherapy is the area of medicine which deals with the practice of medicinal plants as remedies for illnesses or as therapeutic agents. Due to its budget-friendliness, high accessibility, and long account of effectivity, plant- based therapy as complementary and alternative medicine (CAM) is widespread in the first world while remains the primary health care for the third world. The more traditional use of plant-based therapy for medicinal purposes is to preserve the original properties of the plant;vitiated components are minimum. Even with its popularity, information regarding phytotherapy and the benefits of herbs and plants is nil. Even with its utilization among people, especially with the guidance of the elderlies, the knowledge is still lacking. This may be due to the fact that the practice of phytotherapy is usually based on experience and information is passed down through verbal transmission. The main objective of the study is to implement an Android application that acts as a leaf identification system, capable of detecting whether a plant has medicinal properties or not through the captured leaf image and its patterns. It displays their therapeutic benefits to the human body, its preparation, administration, dosage and frequency and duration of usage.

Electrical impedance tomography (EIT) is a non-invasive imaging modality that can provide information about dynamic volume changes in the lung. This type of image does not represent structural lung information but provides changes in regions over time. EIT raw datasets or boundary voltages are comprised of two components, termed real and imaginary parts, due to the nature of cell membranes of the lung tissue. In this paper, we present the first use of EIT boundary voltage data obtained from infants for the automatic detection of apnea using machine learning, and investigate which components contain the main features of apnea events. We selected 15 premature neonates with an episode of apnea in their breathing pattern and applied a hybrid classification model that combines two established methods;a pre-trained transferlearning method with a convolutional neural network with 50 layers deep (ResNet50) architecture, and a support vector machine (SVM) classifier. ResNet50 training was undertaken using an ImageNet dataset. The learnt parameters were fed into the SVM classifier to identify apnea and non-apnea cases from neonates' EIT datasets. The performance of our classification approach on the real part, the imaginary part and the absolute value of EIT boundary voltage datasets were investigated. We discovered that the imaginary component contained a larger proportion of apnea features.

Humans have been long dreaming of obtaining the ability of changing electromagnetic (EM) attributes intelli-gently according to the environment so as to camouflage just as chameleons do. Thanks to the unprecedented high degree of freedom in manipulating EM waves, metasurfaces can mimic EM characteristics of various en-vironments vividly and have pushed a giant step towards this long-desired dream. Nevertheless, for most met-asurfaces, the EM characteristics are fixed and thus cannot be altered according to changing environments, which hinders their applications in intelligent scenarios such as moving target camouflage. With the aim to achieve intelligent camouflage, in this work we propose a chameleon-like framework for intelligent camouflage based on EM metasurface, which integrates transfer-learning-empowered perceptron into a reconfigurable metasurface. As a demonstrative example, a chameleon-like intelligent camouflage metasurface (CLICM) system with robust extendibility was developed and measured in laboratory. The system can dynamically control the reflection spectrum in 5.1-6.5 GHz according to what it sees. Both the simulation and experiment results verify this framework. This work provides a perceptron-algorithm-metasurface framework with robust extendibility for intelligent EM manipulation and may find wide applications in camouflage and wireless communication.
