    Abstract The Internet of Things (IoT) has attracted much attention from society, industry and academia as a promising technology that can enhance day to day activities, and the creation of new business models, products and services, and serve as a broad source of research topics and ideas. A future digital society is envisioned, composed of numerous wireless connected sensors and devices. Driven by huge demand, the massive IoT (mIoT) or massive machine type communication (mMTC) has been identified as one of the three main communication scenarios for 5G. In addition to connectivity, computing and storage and data management are also long-standing issues for low-cost devices and sensors. The book is a collection of outstanding technical research and industrial papers covering new research results, with a wide range of features within the 5G-and-beyond framework. It provides a range of discussions of the major research challenges and achievements within this topic

    Abstract The traditional evaluation criteria of coordination analysis were based on the classification of fixed interval index. Clustering methods serve to redefine the criteria and improve the accuracy of the coordination analysis. The improved algorithm was adopted to analyze the spatial coordination between Chinese higher educational institutions and employment population. It was discovered:1.The regional imbalance of the higher educational institutions was less serious than that of the employment population;2.Although the coordination level of developing regions in the south-central and north-east was lower than that of western border and eastern coastal regions, all those regions globally maintained a high level of coupling and coordination; 3. Inclusive regional development strategies could be adopted to optimize the coordination between education and employment.

    Abstract As the main base for training teachers, normal colleges and universities can not only reserve a large number of talents for the construction of teachers but also help to improve the professional quality and teaching ability of teachers. Carrying out research on music education in normal colleges and universities can further meet the diversified needs of the current society for music talents and promote the improvement of art cultivation and cultural level of music students in normal colleges and universities. This paper discusses the preparation work of higher normal music colleges under the new curriculum standards from four aspects: "experience learning, independent learning, cooperative learning, and inquiry learning." Later, through the method of questionnaire survey, starting from the survey of the independent learning motivation of 325 music education students, the independent learning situation of music education students under the network resources was analyzed, and the learning strategies were discussed from various aspects of students, teachers, and the school. By analyzing the current situation of music teaching in higher teacher training colleges from many aspects, and putting forward relevant suggestions according to the survey results, we hope to help the transformation of music teaching methods in the future and make contributions to the field of music teaching in China.

    Abstract Credit evaluation is a difficult problem in the process of financing and loan for small and medium-sized enterprises. Due to the high dimension and nonlinearity of enterprise behavior data, traditional logistic regression (LR), random forest (RF), and other methods, when the feature space is very large, it is easy to show low accuracy and lack of robustness. However, recurrent neural network (RNN) will have a serious gradient disappearance problem under long sequence training. This paper proposes a compound neural network model based on the attention mechanism to meet the needs of enterprise credit evaluation. The convolutional neural network (CNN) and the long short-term memory (LSTM) network were used to establish the model, using soft attention, the gradient propagates back to other parts of the model through the attention mechanism module. In the multimodel comparison experiment and three different enterprise data experiments, the CNN-LSTM-ATT model proposed in this paper is superior to the traditional models LR, RF, CNN, LSTM, and CNN-LSTM in most cases. The experimental results under multimodel comparison reflect the higher accuracy of the model, and the group test reflects the higher robustness of the model.
