SVD++ Linear Regression Recommendation Algorithm with Time Effect

Aiming at the problem of data sparsity in traditional collaborative filtering algorithm,this paper proposes a recommended algorithm named timeSVD++ LR,which introduces the time effect attribute on the basis of the SVD++ algorithm and linear regression model.The SVD++ algorithm is used to map the use...
