METHODS AND APPARATUSES FOR INFORMATION PROCESSING AND INFORMATION RECOMMENDATION ELECTRONIC DEVICE STORAGE MEDIUM AND COMPUTER PROGRAM PRODUCT

摘要

The present disclosure discloses an information processing method, an information processing apparatus, an information recommendation method, an information recommendation apparatus, an electronic device, and a storage medium, and relates to the field of artificial intelligence, in particular, a recommendation system and a deep learning technology field. In the information processing method of the present disclosure, the computing device obtains a tree structure parameter of a tree structure, and the tree structure is for indexing a set of objects for recommendation. The computing device obtains a classifier parameter of the classifier, and the classifier is for predicting a set of preferred nodes in which the rank of the probability preferred by the user in each layer is preceded by one layer down from the top layer of the tree structure, where the one layer The preferred node set of ' is determined based on the preferred node set of the upper layer. The computing device builds a recall model based on the tree structure parameter and the classifier parameter. The recall model constructed according to an embodiment of the present disclosure uses the tree structure parameter and the classifier parameter as model parameters to optimize the training process and use process of the recall model, thereby improving the recall result of the recall model.
