DATA PUSHING METHOD AND SYSTEM, ELECTRONIC DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2021/169218

A1

A data pushing method and system, an electronic device and a storage medium, which relate to the field of intelligent decision making. Said method comprises: extracting, according to webpage browsing information, personal features related to data pushing (S110), and recording and storing a personal behavior policy; defining, in combination with the personal features and the personal behavior policy, a reward function (S120); abstracting a real process of item recommendation as a Markov process on the basis of the reward function (S130); using the Markov property of the Markov process to simplify a Bellman equation to form an iterative equation, calculating an optimal solution of the iterative equation, and obtaining a data pushing model (S140); inputting million-level data as data features into the data pushing model to perform network training, so as to form an optimal data pushing model; and inputting personal features of a data pushing target user into the optimal data pushing model, and the optimal data pushing model automatically outputting recommendation information to said target user (S160).
