Abstract
(EN)
In various examples there is a data retrieval apparatus. The apparatus has a processor configured to receive a data retrieval request associated with a user. The apparatus also has a machine learning system configured to compute an affinity matrix of users for data items. The affinity matrix has a plurality of observed ratings of data items, and a plurality of predicted ratings of data items. The processor is configured to output a ranked list of data items for the user according to contents of the affinity matrix.

La présente invention concerne, dans divers exemples, un appareil de récupération de données. L'appareil comprend un processeur configuré pour recevoir une demande de récupération de données associée à un utilisateur. L'appareil comprend également un système d'apprentissage automatique configuré pour calculer une matrice d'affinité d'utilisateurs pour des éléments de données. La matrice d'affinité a une pluralité d'évaluations observées d'éléments de données et une pluralité d'évaluations prédites d'éléments de données. Le processeur est configuré pour fournir en sortie une liste classée d'éléments de données pour l'utilisateur en fonction du contenu de la matrice d'affinité.
