2013 chapter
Personalizing Embedded Assessment Sequences in Narrative-Centered Learning Environments: A Collaborative Filtering Approach
In Lecture Notes in Computer Science (pp. 369–378).
TL;DR:
This paper compares two model-based collaborative filtering methods, including probabilistic principal component analysis and non-negative matrix factorization (NMF), to a memory-based baseline model, k-nearest neighbor, and suggests that PPCA provides the most accurate predictions on average, but NMF provides a better balance between accuracy and run-time efficiency.
