چکیده

Recommender systems are most often approached from a number-crunching perspective, even though recent algorithms are very similar to methods used in psychology. Based on these similarities this study tried to investigate if the prediction models produced by a matrix factorization algorithm can be interpreted like is done in more psychological studies. Multidimensional scaling was used on data gathered via an online cardsort to establish the psychological attributes people perceive in movies. These attributes were then partially retrieved in the matrix factorization model.

A new approach for building recommender system using non negative matrix factorization method

Nonnegative Matrix Factorization is a new approach to reduce data dimensions. In this method, by applying the nonnegativity of the matrix data, the matrix is ​​decomposed into components that are more interrelated and divide the data into sections where the data in these sections have a specific relationship. In this paper, we use the nonnegative matrix factorization to decompose the user ratin...
