Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] see figure 1 , methods include:

[0055] Step S201: Obtain the users who use the website and the dominant features of the users;

[0056] The website records user-related information, such as user registration information, user access information, etc. Among them, user-related information is usually stored in the statistical data in the background of the website, and who uses the website can be obtained through statistical data, for example: Statistical data records that Zhang San and Li Si registered as users of the website, then it can be known through statistical data that Zhang San and Li Si have used the website. Of course, the relevant information of the users is required to be true, such as: real name, real age, etc. Wait.

[0057] The dominant feature of the user is the feature obtained directly. For example, if the real name of the ...

Abstract

A method and apparatus for estimating recessive character distribution of users. The method comprises: acquiring users using a website and dominant characters of the users; acquiring character information of the whole population from a population database, the character information comprising dominant characters and recessive characters; and calculating recessive character distribution of the users according to the character information of the whole population, the users using the website, the dominant characters of the users and a Bayesian algorithm. By means of the method, an estimation result is more accurate when recessive characters of users are estimated.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for estimating the distribution of hidden features of users. Background technique [0002] Usually, when using a website, a user needs to register as a user of the website, and when a user registers as a user of the website, he needs to fill in registration information, such as user name, ID number, and so on. [0003] If the website manager needs to carry out accurate advertising marketing and push different advertisements to different users, it is not enough to rely solely on user registration information, and more user information is needed. Information, for example: know the user's name, want to estimate the user's age, race, gender, etc. [0004] In the prior art, estimating recessive features through known explicit features is implemented according to the Bayesian equation, as follows: [0005] Suppose x is the hidden feature of the user we are intere...
