Information observation method and information observation device

A method receives user behavior information at a first system. The user behavior information is determined by user interaction with a first list sent to the user by a first network on a video delivery service. A first state is generated using the received user behavior information and prior user behavior information by the user from cells that store the prior user behavior. The method inputs the first state into a second network with the first recommendation list to generate a value that evaluates a performance of recommending the first recommendation list. An update to parameters is generated for the first network and provided to the first network. The first network generates a second state from the received user behavior information and prior user behavior information derived from cells that store the prior user behavior and outputs a second recommendation list using the second state and updated parameters.

Reinforcement learning network for recommendation system in video delivery system

A method receives ratings for videos from a first user that is using a video delivery service. A first model includes connection networks where each connection network corresponds to a rating. The method inputs each rating into a connection network in an order. Also, parameters for the ratings and ratings other than the rating received from the first user are modeled in a respective connection network. Values for the set of parameters are trained such that the plurality of connection networks predict conditional probabilities that the first user would provide the rating corresponding to the each connection network in the order. The conditional probabilities are based on the first user providing ratings that are previously located in the order. The parameters are then used to generate a list of videos to recommend to the first user using the first model.

A method receives a candidate set of recommendations for video entities on a video delivery service in response to receiving a request to generate a page of an interface. A number for each recommendation is generated that represents a relevance rating of the respective recommendation minus a similarity rating between the respective recommendation and recommendations from the candidate set of recommendations that are added to a subset of recommendations. A recommendation is added to the subset of recommendations that has a maximum probability of being relevant to the user and diverse from the recommendations in the subset of recommendations based on the number. The method then updates the number for recommendations in the candidate set of recommendations based on adding the recommendation to the subset of recommendations.
