Inferring prerequisite relations between educational\nconcepts is required for modern large-scale online educational technology\napplications such as personalized recommendations and automatic curriculum\ncreation. We present PREREQ, a new supervised learning method for inferring\nconcept prerequisite relations. PREREQ is designed using latent representations\nof concepts obtained from the Pairwise Latent Dirichlet Allocation model, and a\nneural network based on the Siamese network architecture. PREREQ can learn\nunknown concept prerequisites from course prerequisites and labeled concept\nprerequisite data. It outperforms state-of-the-art approaches on benchmark\ndatasets and can effectively learn from very less training data. PREREQ can\nalso use unlabeled video playlists, a steadily growing source of training data,\nto learn concept prerequisites, thus obviating the need for manual annotation\nof course prerequisites.","url_abs":"http://arxiv.org/abs/1811.12640v2","url_pdf":"http://arxiv.org/pdf/1811.12640v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"inferring-concept-prerequisite-relations-from","repo_url":"https://github.com/suderoy/PREREQ-IAAI-19","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[{"method_slug":"siamese-network","method_name":"Siamese Network"}],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
