Squirrel AI Learning: Intelligent Adaptive Education Technology Changes Education Pattern
At this IROS 2019 conference, Dr. Wei Cui introduced in detail to the participants how the Squirrel AI Learning intelligent adaptive education system can make its own contribution to the industrialization of education through the empowerment of AI technology.
At the technical level, Squirrel AI Learning fully uses more than ten kinds of artificial intelligence algorithm technologies, such as knowledge space theory, Bayesian theory, logistic regression, genetic algorithms and deep learning, and initiates the nanoscale knowledge point decomposition, the decomposition of MCM system (Model of Thinking, Capacity and Methodology), and the deep decomposition of knowledge points, clearly and accurately penetrates the students' knowledge loopholes/weaknesses; the nanoscale knowledge point splitting created originally by Squirrel AI Learning splits the knowledge points in the disciplines into nanoscale knowledge point splitting.
Through the correlation between knowledge points, students' user portraits can be visualized, so as to have a clearer understanding on the grasp of students' knowledge points and accurately detect the weak points of students' knowledge points. On the basis of nanoscale knowledge point decomposition, the learning abilities and learning methods of Squirrel AI Learning for students are split into measurable and teachable learning ability models.
On this basis, Squirrel AI Learning intelligent adaptive learning system can accurately detect the weak points of learning knowledge, accurately give the most suitable learning path for each child, so as to achieve personalized learning program. The association concept algorithms of non-associated knowledge points created by Squirrel AI Learning not only establishes the relevance of knowledge points based on the knowledge map theory, tracing the source to present, but also establishes the association probability on the non-associated knowledge points, so that the test efficiency and learning efficiency can be improved by 3-10 times respectively than the knowledge map theoretical model of similar products.
It is worth mentioning that Squirrel AI Learning is the first one in the world to put forward the concept of reconstructing knowledge map of fault causes. It sums up the mistakes of every student's knowledge points so as to find the root of problems. And this is also the basis of achieving a real personalized learning program.
In the past, in order to cover the blind area of knowledge points, students often had to carry out the excessive assignments tactics to eliminate illiteracy. Squirrel AI Learning scans the students' knowledge map to accurately locate the blind area of their knowledge. Students do not need to consolidate their knowledge in hundreds of thousands of exam questions. The system will help students quickly according to their weak points of knowledge, so that students' learning efficiency can be maximized, and their performance can be ensured to be improved steadily.
Dr. Wei Cui introduced that at present, in terms of technical characteristics, Squirrel AI Learning is mainly applied to several major AI technologies:
First, evolutionary algorithms, logistic regression and neural networks. The algorithm model takes into account the learning objectives and knowledge state of students, and dynamically adjusts the learning path. The system will gradually draw students' learning habits, interests, methods and other multi-directional student portraits, and continuously optimize the content recommendation logic automatically.
Second, machine learning, deep learning and natural language processing technology. The technology can recommend the most suitable learning content according to different students' personal preferences, learning habits and learning styles. Different students have different degrees of adaptation to different learning atmospheres and difficulties, using natural language processing technology to automatically generate learning content labels; using deep learning technology to analyze student portrait and learning content, and automatically select the suitable learning content for students.
Third, Bayesian theory and Bayesian networks. Look at problems dynamically based on experience and information. The system will render the knowledge points and probability distribution, and predict the learning ability of learners. By comparing the correlation between different knowledge points and the learning degree of students on knowledge points, Squirrel AI Learning intelligent adaptive learning system can infer the correlation between knowledge points without logical relationship.
Fourth, graph theory, knowledge space theory and information entropy theory. Squirrel AI Learning distinguishes between knowledge points according to difficulty, importance and cognitive level, models knowledge system, builds "Knowledge Map", and combs the logic and cognitive correlations between knowledge points.
From the perspective of measurement, information can be quantified. By using the theory of information entropy, we can quickly approach the level of students' knowledge state by detecting some important knowledge points, and then make repeated refined calculations around this basic level, so as to effectively and accurately diagnose students' knowledge loopholes and states.
Fifth, knowledge tracing theory. The system will evaluate the ability level of students at each knowledge point, and analyze the ability level of knowledge points and related knowledge points successively, and finally accurate to the grasp of each nanoscale knowledge point, and update the ability value changes of students in real time after learning, so as to accurately push the most suitable learning path and learning content for the current situation of students. It can not only understand the degree of mastery of students' current knowledge points, but also reflect students' potentiality, which is a kind of prediction.
Sixth, education data mining and learning analysis technology. Education data mining refers to the quantitative analysis of learning process and learning behavior, and collect the learning data of students in the process of learning, including learning time, residence time and test accuracy, etc. Through the processing and analysis of data, different students' learning models are established. Learning analysis technology is mainly used to predict and monitor students' test results, which can provide teachers with detailed student data and information for the system and teachers to improve teaching methods.
Seventh, it is under research that user interaction driven by Dialog-based HUI and VPA engine in the form of dialogue realizes real-time voice interaction between virtual teachers and students. The main technologies are natural language processing, voice recognition and semantic analysis. In the process of learning, students can ask virtual teachers about their learning situation and learning tasks at any time, and give feedback on questions.
Eighth, MIBA is another project working with both SRI and CMU. MIBA refers to the Multi-modal Integrated Behavior Analysis. It collects students' physiological data and behavioral data through cameras, brainwaves measuring rings and other devices, including facial expression data, blood change data under the skin, body movement data and brain wave data. Combined with the learning data generated during the learning process, it analyzes the learning state of students, including the degree of students' concentration and learning input. The teacher terminal system used by teachers can receive early warning signals, and can timely implement personalized intervention to make learning more effective.
Dr. Wei Cui said that just because of the integration of technology, at present, Squirrel AI Learning has established laboratories in cooperation with several top AI research institutes around the world such as CMU, SRI, etc. Squirrel AI Learning intelligent adaptive learning system has opened more than 2,300 learning centers in more than 700 cities and counties in more than 20 provinces, with a total of nearly 2 million registered students.
After understanding the practical application effect of leading algorithms, model and intelligent adaptation technology of Squirrel AI Learning, experts and scholars and participants on site highly praised the achievements of Squirrel AI Learning in research and development and the application of AI technology in the field of education, as well as the behavior that it is committed to bringing fair, efficient and personalized education to every child.
At last, Dr. Wei Cui said that traditional education currently faces many deep-rooted problems: the development of education resources is uneven, high-quality education resources tend to developed areas, while in the underdeveloped areas, the quality of teachers is uneven. Squirrel AI Learning by Yixue Group hopes to achieve the education concept that we have been advocating since ancient times through the empowerment of AI technology: teaching students according to their aptitude, to reform and innovate traditional education.
