Embodiment Construction

[0064] The specific embodiments of the present invention will be described in detail below. The following algorithm will help those skilled in the art to further understand the present invention, but does not limit the present invention in any form. It should be pointed out that for those of ordinary skill in the art, a number of modifications and improvements can be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0065] This embodiment provides a method for evaluating program quality based on the Hawkes process, which includes the following steps:

[0066] Step a, data preprocessing: use the record of user viewing behavior as raw data, and process the raw data into a sequence of user viewing events;

[0067] Step b, on the basis of the user viewing event sequence, use the Hawks process to establish a user viewing event sequence model, randomly initialize the parameter values ​​of the conditional...

Abstract

The invention provides a program quality evaluation method based on a Hawkes process. The method comprises the steps that the original data of a user viewing behavior are abstracted into a point process, wherein only the time point, the program number, the program type and the channel number of the user viewing are included; the influence of subjective and objective factors such as the user viewing wish, the user preference and the channel preference on the program quality evaluation is ruled out; the influence of objective factors such as the program type on the program quality evaluation is ruled out; and the behavior of each user's viewing program is modeled through a Hawkes model. According to the invention, the minimum window gradient descent algorithm is used; the parameters of the established model are acquired by calculating the user data; and the program quality and the program type are evaluated.

Description

Technical field [0001] The present invention relates to the technical field of program quality evaluation, in particular to a program quality evaluation method based on the Hawkes process. The method models user viewing program behaviors and uses data calculation methods to evaluate program quality algorithms. User viewing behavior modeling can exclude user viewing intentions, program types, channel preferences, user preferences and other factors to obtain an objective evaluation of program quality. Background technique [0002] The traditional evaluation of program quality is achieved by statistically investigating the ratings of programs, but this method cannot exclude the interference of users’ viewing willingness, program types, channel preferences, and user preferences, and cannot obtain a more objective evaluation of program quality. Quality evaluation. Specifically, these interferences include the user’s own viewing willingness, the time when the program is broadcast, the...
