The experimental data show that the learning effect score is 85.2 points in the 4-week learning period of the experimental group, which is obviously higher than 63.1 points of the control group, so that the system of the invention obviously improves the personalized teaching effect.
Average learning time the average learning time of the experimental group was 28.6 hours, which was 20.1% less than 35.8 hours of the control group. This shows that the inventive system effectively reduces the time required for learning through real-time feedback and personalized path optimization.
User satisfaction-Experimental groups using the system of the invention user satisfaction scores 4.7 points, 3.5 points higher than control groups. The result shows that the system of the invention provides better user experience and learning participation.
The success rate of data leakage detection is that in 20 times of simulated attack tests, the system successfully detects all 20 times of data leakage attempts, the success rate is 100 percent, and the success rate of comparison components is 60 percent (12/20). The system of the invention has stronger safety protection capability.
The privacy protection rate of the system is 98.5%, which is obviously better than 85.0% of the control group, and the system is excellent in protecting the user data privacy.
Experimental data shows that the AI art teaching management system is remarkably superior to the prior art in the aspects of personalized teaching effect, learning time optimization, user satisfaction improvement, data safety and privacy protection.
In summary, the invention innovatively uses an improved multi-modal deep ensemble learning algorithm (MMDILA) to significantly improve data fusion and analysis capabilities. Unlike the prior art, the present invention is capable of simultaneously processing multiple data types (such as text, image, voice and video) of a user and efficiently analyzing the data through Convolutional Neural Network (CNN), natural Language Processing (NLP) and emotion recognition model. The innovative data processing mode realizes more comprehensive and more accurate user behavior understanding, so that the invention can generate and dynamically adjust the learning path according to the personalized requirements of the user, and the effect and pertinence of personalized teaching are obviously improved.
The invention introduces a reinforcement learning algorithm, establishes a real-time feedback and dynamic optimization mechanism, and can continuously adjust course content and teaching strategies according to real-time performance and feedback of users. Compared with the feedback mode relying on fixed rules or simple scores in the prior art, the method can provide more instant and accurate personalized suggestions, so that the learning time is effectively shortened, and the learning efficiency is improved. The innovative interaction mechanism enhances the user experience and increases the learning investment and satisfaction of the user.
The invention provides a brand new data security and privacy protection scheme through an integrated block chain technology and a differential privacy technology. The block chain technology ensures transparency and non-tamper property of data operation, and the differential privacy technology effectively prevents leakage of sensitive information of users in the data analysis and use processes. In addition, the invention also introduces an abnormality detection model, and can monitor and cope with potential data leakage and illegal access risks in real time. Compared with the single encryption or access control measures in the prior art, the method and the device realize higher level protection in terms of data security and privacy protection.
The invention adopts a modularized system architecture design, and each functional module (such as user management, course generation, interactive feedback, data security and the like) works independently and cooperatively. The architecture design not only improves the expansibility and compatibility of the system and is convenient for subsequent function development and system upgrading, but also reduces the maintenance cost and complexity of the system. Compared with a relatively closed and inflexible system architecture in the prior art, the design of the invention can better adapt to different user requirements and use scenes, and has wide market application potential.
The invention verifies the remarkable advantages of the invention in the aspects of personalized teaching effect, learning time optimization, user satisfaction improvement, data safety and privacy protection through a large amount of experimental data. Experimental results show that the personalized teaching effect score of the system is improved by 35%, the learning time is reduced by 20%, the user satisfaction is increased by 34%, and the system is excellent in data leakage detection and privacy protection.
