Embodiment 1
[0159] The intelligent learning state tracking method and system based on the multi-task framework specifically include:
[0160] (1) Collect learners' external learning behavior characteristics and learning resource characteristics from the learner's answer sequence, use item response theory to mine learners' potential ability characteristics, and then perform a series of preprocessing operations on these characteristics, so as to obtain Learned features from prior information;
[0161] (2) Design multiple stacked convolutional neural networks to perform deep representation learning on the learning features containing prior information, and control the forgetting of learners while capturing the learning rate of learners in different periods, so as to construct deep learning features;
[0162] (3) Integrate deep learning features, external learning behavior features, and learning resource features into deep and shallow features, and creatively introduce bidirectional recurrent...
