With the growing popularity of online learning and blended learning, as well as the rapid development of cloud computing and big data technology, scalable computing infrastructure has become an indispensable part of building a modern education platform. Method: Five experiments were conducted to test the scalability and reliability of computing infrastructure based on online and blended learning environments. The experiments include the performance comparison of online learning platforms based on different virtualization technologies, the performance comparison of online and hybrid learning environments under different loads, the comparison of online learning experiences under different bandwidth constraints, the system stability test under different user numbers, and the comparison of access speeds in different regions. Result: The experimental results showed that on an online learning platform using the KVM (Kernel-based Virtual Machine) interface, when the number of concurrent users is 99, the response time is 100.9ms, and the CPU (Central Processing Unit) utilization rate is 60.9%. Under low load conditions, the concurrent access volume is 200; the response time is 50ms, and the throughput is 10.3. When accessing locally, the latency is 9.19ms; the download speed is 500.3KB/s; the network throughput is 399.8KB/s.

Unmanned Aerial Vehicles (UAVs), also known as drones, have rapidly gained popularity due to their widely employed applications in various industries and fields, including search and rescue, agriculture, industry, military operations, safety, and more. Additionally, drones assist with tasks such as search and rescue efforts, pandemic virus containment, crisis management, and other critical operations. Due to their unique capabilities in image, video, and information collection, a multi-UAV system plays a crucial role in these activities. However, such images and video data involve individual privacy. Therefore, such multi-UAV applications have an indigenous tradeoff of privacy preservation. We have proposed a Federated Learning (FL) based approach for ensuring privacy in multi-UAV applications. The proposed methodology utilizes a synchronous FL approach and the Convolutional Neural Network (CNN) to ensure security. The model parameters are protected by using a secure aggregation. Results demonstrate that the proposed approach outperforms existing techniques in terms of accuracy and precision.

The implementation of innovation and entrepreneurship education is inseparable from professional education, so it is important for the rich data in the education platform to mine the connection between professional courses and between grades and courses. The study of association rule algorithm based on education data mining improves the time performance efficiency and accuracy of Apriori algorithm. The study improves the time efficiencies of Apriori algorithm by maintaining Map table and splitting transaction database; the accuracy is improved by using mixed criteria to measure the accuracy and filtering deformation rules based on the inference of confidence. The results of the validation of the time efficiency of the algorithm show that the running time of the improved algorithm in solving frequent itemsets is improved by about 93.86%, 92.48% and 92.76%, respectively, compared with the other three algorithms. The running time of the algorithm for generating frequent itemsets of all orders is about 91.35 ms, which is 66.13% and 83.72% better than the Apriori algorithm and AprioriTid algorithm, respectively.

The process of learning any new technology requires acquiring the best knowledge about the information of that technology. The better the knowledge humans get about digital technology, the more they become efficient in implementing technological development. In developing the musical rhythm and tuning, the application of programming technologies helps improve the quality. In constructing networking sites and sensing technologies, algorithmic learning processes help in effective development. This development occurs by making the systematic process of transforming a data processing language and data interpreter. Thus, it helps in performing programming effectively in the present as well as future purposes. Therefore, it reflects all the benefits of machine learning. Thus, the preference for machine learning increases technological impact. This development of the programming used in the computer makes humans learn about something easily and get the best information. The effectiveness of the technological development by the algorithm used in the data processing implements the best way to improve the technological language transformation from human language to computer operating language. There is a transnational perspective of the average beat commonness of each part of the music. “Reinforcement algorithms-based learning” incorporated with sensor networks has proposed compelling opportunities for improving “music improvisation” and interpretation.

In light of Internet+, how to make network technology better serve the educational cause needs more exploration. The online and offline hybrid education model that integrates MOOC is a new attempt. The sports safety of college students is the premise for the smooth development of sports activities. Therefore, a mixed teaching mode of sports safety combined with MOOC is designed to evaluate the teaching effect. However, under this teaching mode, the commonly used teaching effect evaluation methods cannot adhere to formative evaluation standards. Consequently, to better evaluate the MOOC teaching mode, a model for evaluating instructional effects based on RF mixed teaching mode is constructed. Aiming at the defects of RF in data processing, a genetic algorithm and particle swarm algorithm are used to optimize random forest. The outcomes demonstrate that the enhanced PSO-RF evaluation model has a 98.68% accuracy rate, which is 5.44% and 3.49% higher than the RF and GA-RF model respectively. Therefore, the enhanced PSO-RF-based teaching effect assessment model can better assess the mixed teaching mode in sports safety, meeting the evaluation requirements for students’ learning effects.

The current overall layout planning model matrix of landscape ceramic sculpture is generally unidirectional, and the planning efficiency is low, resulting in a decline in the layout optimization ratio of the model. Therefore, the design and verification analysis of landscape ceramic sculpture’s overall layout planning model based on the Nondominated Sorting Genetic Algorithm (NSGA - II) algorithm is proposed. According to the actual planning needs and standards, first set the basic layout points, establish a cross-planning matrix in a multi-level manner, and improve the efficiency of the overall layout planning of the sculpture. The NSGA - II calculation landscape ceramic sculpture layout planning structure is constructed on this basis, and the model design is realized by level conversion. This novel NSGA-II with level conversion performs better layout planning when compared with other conventional models. The final test results show that through three stages of layout optimization processing, compared with the initial planning layout, the optimal layout optimization ratio for the setting of the plaza sculpture can reach more than 60%, indicating that with the help of this method, the layout planning of sculpture has been further improved, the space has been expanded, and has practical application value.
