SAKT:self attentive knowledge tracing. 知识追踪(Knowledge tracing)的任务是模拟每个学生在一系列学习活动中对知识概念的掌握情况。最近几年,基于RNN(Recurrent Neural Networks)方法,如 Deep Knowledge Tracing (DKT) 和Dynamic Key-Value Memory Network (DKVMN) 取得了很好的结果。但是这些模型有个问题是,不能很好...
本文提出了一种基于自注意力机制的知识追踪模型 Self Attentive Knowledge Tracing (SAKT)。其本质是用Transformer的 encoder 部分来做序列任务。 任务描述 利用学生的交互序列X=(x1,x2,…,xt)其中xt=(et,rt)预测学生下次的表现即预测p(rt+1=1∣et+1,X) 方法 这里首先列举使用到的符号 模型架构如下 输入编码...
In this paper, we propose a novel Sequential Self-Attentive model for Knowledge Tracing (SSAKT). SSAKT utilizes question information based on Multidimensional Item Response Theory (MIRT) which can capture the relations between questions and skills. Then SSAKT uses a self-attention layer to capture...
The self-attentive knowledge tracing (SAKT)18 has been the first method to adopt attention mechanisms in the context of KT. Attention mechanisms are more flexible than recurrent and memory-based neural networks. Extensive experiments on a variety of real-world datasets suggest that the SAKT model...

The task of knowledge tracing involves establishing a model that characterizes the mastery level of individual students in relation to knowledge concepts (KCs), as they engage with a sequence of learning activities. Each student's knowledge is modelled by estimating the student's performance on the...
To resolve the above issues, we develop a novel KT model with the heterogeneous hypergraph network (HHN) and propose an attentive mechanism, including intra-and inter-graph attentions, to aggregate neighbors' information upon HHN. To further enhance the question representation, we supplement the ...
as well as exploring knowledge independently through pre-class preview and post-class review. Three students mentioned challenges with the flipped learning. They found that they needed to spend more time and effort on preview before class and be more attentive during class to participate in discussio...
(a literal Latinstatus, or position) to be sitting with both feet on the floor, hands at rest, gazing frontward. Such posture is imagined to reflect attentive studenthood, and indeed, is used as a measure of engagement in learning analytics (e.g., De Carolis et al.,2019). We ...
