Algorithms such as collaborative filtering, DeepFM and Deep Matrix Factorization can be deployed in different commercial environments without a lot of fundamental modifications. Although there has been hot debate among academic scientists and industrial product owners, environment-sensitive algorithms remain a practice only in real world applications. In this paper, we discuss the topic whether collaborative filtering algorithm is a justified valid model by topological analysis of the problem structures. We claim that the validity of the algorithm is related to the shape of the input data domain.<\/jats:p>","DOI":"10.3233\/faia231233","type":"book-chapter","created":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T12:56:35Z","timestamp":1705064195000},"source":"Crossref","is-referenced-by-count":0,"title":["Collaborative Filtering Is a Lie or Not?
