Patent Name: Tree Enhanced Embedding Model Predictive Analysis Methods and Systems

Patent No: 20190325293A1 (US)

Publication Date:  24 Oct 2019

Filing Date: 18 Apr 2018

Country to be Filed: USA

Description: Methods and systems for predictive analysis are disclosed. A predictive analysis method comprises receiving input data comprising an indication of a user, an indication of an item, a user feature vector indicating features of the user and an item feature vector indicating features of the item; and constructing a cross feature vector indicating values for cross features between features of the user and features of the user. Embedding vectors derived from the cross feature vector, the user feature vector and the item feature vector are input into an attention network to determine a set of attentive weights which indicate cross features between the user and item features. These cross features are used in the identification of a user item preference.
