TL;DR: In this article, a delicious food recommendation method based on a multi-index probability matrix decomposition model is proposed, and the method comprises the following steps: (10) constructing a single-index scoring matrix: constructing a user-project-single-index context scoring matrix according to a user purchase record; (20) constructing an index-based scoring matrix in a multiindex environment according to the user purchase records; and (30) solving a scoring matrix to obtain a plurality of scoring values, and selecting the information with the maximum scoring value to be recommended.
