Publication number: 20220138798Abstract: A method, system, and apparatus provide the ability to personalize a digital channel. A digital channel is provided to multiple users and visitor information at each visit is collected. The visitor information includes data about each visit and multiple content items that are presented. The users are autonomously clustered by segmenting the user population into behavioral groups such that mutual information is maximized between the users in an assigned behavioral group and the content items. Based on the clustering, a model is generated that estimates a score for each interaction between users and content items. The model is updated at a defined interval. Based on the score, content items to recommend to a specific user are determined. The recommendation jointly maximizes an outcome and a learning speed of the model. The personalized digital channel is delivered to the specific user based on the recommended multiple content items.Type: ApplicationFiled: October 30, 2020Publication date: May 5, 2022Applicant: Sitecore Corporation A/SInventors: Marc Perreau Guimaraes, Tetiana Kostenko, Samira Sadeghi, Mingde Xu, Abhishek Soni, Romeo B.
