Research on the Application of Reinforcement Learning Model in Vocational Education System

Vocational education can effectively improve the vocational skills of employees,improve people’s traditional concept of vocational education,and focus on the training of vocational skills for students by using new educational methods and concepts,so that they can master key vocational skills and develop key abilities.In this paper,three different learning models,Deep Knowledge Tracing(DKT),Dynamic Key-Value Memory Networks(DKVMN)and Double Deep Q-network(DDQN),are used to evaluate the indicators in the vocational education system.On the one hand,the influence of learning degree on the performance of the model is compared,on the other hand,the performance evaluation of three models under the same learning effect is compared,so as to obtain the best learning model applied to the field of skill training.In order to accurately evaluate the learning status of students,the loss function curves under three models are compared.Finally,the error rate of students in vocational skills education tends to be zero,and the learning process of intensive learning effectively improves students’mastery of skills and key abilities.

Bilinear pair based authentication protocol for wireless medical sensor network

With the development of wirdess network and electronic technologies, the wireless sensor network （WSN） has been widely used in many applications. One of the most important applications is wireless medical sensor network （WMSN） , which makes modern heahh-care more popular. However, most of the sensor data transmitted in the WMSN is patient-related information. The sensor data are important and should be confidential. In addition, the attackers may also maliciously modify these sensor data. Therefore, both security and privacy are two very important issues in WMSN. A user authentication protocol and data security transmission mechanism based on bilinear pairing is proposed to protect data security and privacy. The proposed protocol enables the medical staff to monitor the health status of health care workers and provide timely and comprehensive health care information to the patient. Finally, through security and performance analysis, it can be found that the proposed authentication and key agreement protocol can resist common attacks such as impersonation attack, replay attack, online or offline password guessing attack, and stolen verifier attack. At the same time, this agreement is also in line with the performance of WMSN application environment.
