RECOMMENDATION SYSTEM USING A TRANSFORMED SIMILARITY MATRIX

摘要

Systems and methods for transforming a similarity matrix used to generate content item recommendation lists are described. The system may determine a weight (used to transform the similarity matrix) sufficient to place one or more content items on the content item recommendation list or at a particular position on the recommendation list. The transformed similarity matrix may further be reduced in size, and content recommendations may be generated using the transformed or reduced similarity matrix.

1. A method comprising:
generating, by a computing device, a list of content items to recommend to a user based on a similarity matrix; responsive to a determination that a first content item was not in the list of content items to recommend to the user, applying a weight to the similarity matrix to generate a weighted similarity matrix; generating a second list of content items to recommend to the user based on the weighted similarity matrix; and determining whether the first content item was in the second list of content items to recommend to the user.
