Do we need to go Deep? Knowledge Tracing with Big Data. (arXiv:2101.08349v1 [cs.LG])

Interactive Educational Systems (IES) enabled researchers to trace student
knowledge in different skills and provide recommendations for a better learning
path. To estimate the student knowledge and further predict their future
performance, the interest in utilizing the student interaction data captured by
IES to develop learner performance models is increasing rapidly. Moreover, with
the advances in computing systems, the amount of data captured by these IES
systems is also increasing that enables deep learning models to compete with
traditional logistic models and Markov processes. However, it is still not
empirically evident if these deep models outperform traditional models on the
current scale of datasets with millions of student interactions. In this work,
we adopt EdNet, the largest student interaction dataset publicly available in
the education domain, to understand how accurately both deep and traditional
models predict future student performances. Our work observes that logistic
regression models with carefully engineered features outperformed deep models
from extensive experimentation. We follow this analysis with interpretation
studies based on Locally Interpretable Model-agnostic Explanation (LIME) to
understand the impact of various features on best performing model
