- the applications and services provided to the user often depend on the age of the user as an important factor in providing an effective service.
- users of different ages may be interested in different services.
- ads, content, apps, and the like are typically designed for a specific age audience. For example, college students usually belong to the group of household consumption, while adults usually belong to the group of household consumption. Therefore, knowing the age range of users can help to provide users with Service.
- relevant advertisements, content, and applications can be pushed to the user in relation to age, so that the user device does not bear the burden of a large amount of other information irrelevant to the age range of the user.
- some services require users to be at a certain age, and product information about children of different ages needs to be targeted at consumers with children of the appropriate age group.
- the age range of the user can be determined by considering multiple aspects of the user. For example, the user's consumption data during a particular time period may reflect the user's age range. For example, a family with a child has a different spending habit than a single person or family without a child, and a family with children of different ages also has a difference. Therefore, analyzing the user's consumption data can estimate the user's age range.
- analysis can be performed for consumption data of a user in a specific time period such as the most recent year.
- the specific time period is selected as the consumption data of the most recent year because the user's age will also increase with the passage of time, and the consumption characteristics of the most recent year reflect the behavioral habits of the current age, along with the user. As the age grows, the user's spending habits will change accordingly, so the annual behavior can be a true reflection of consumer behavior and characteristics during that age.
- time units can be used to more accurately reflect trends or changes in consumption characteristics of a particular age group, for example, three months and six months.
- the e-commerce can set a plurality of predefined age groups in the system, each age group including a specific age range.
- the age range can also be customized by the user. For example, you can divide the age range into the following five segments:
- Paragraph 1 15-18 years old: groups without spending power

Then, the calculation module 111 calculates a probability that each tuple of the test data belongs to each of the plurality of predefined age segments based on the number of users and the number of the third-level categories.
- the selection module 113 selects an age segment to which the maximum probability of the probabilities belongs as the age segment to which the user of the corresponding tuple belongs.
- the comparison module 115 is configured to compare the error between the known age segment and the selected age segment in the test data to obtain a prediction accuracy rate.
- the modeling module 103 outputs a model whose prediction accuracy rate is greater than or equal to a predetermined threshold, preferably outputs a model with a prediction accuracy rate greater than or equal to 0.7.
- the application module 105 calculates the age range of the user using the model output by the modeling module 103, and outputs the calculation result to the presentation module 107.
- modeling module 103 determines that the user age segment is related to the naive Bayesian algorithm.
- the naive Bayesian algorithm is a probabilistic classification algorithm based on very simple points. The class idea, for the given item to be classified, solves the probability of occurrence of each category under the condition of occurrence of this item, and the maximum considers which category the item to be classified belongs to. For example, if the probability of occurrence of a particular user at multiple ages set by the e-commerce is determined, the age segment in which the greatest probability occurs is the age segment to which the particular user belongs.
- Xk has two cases of classification attribute and continuous attribute. In this model, it is a classification attribute. If the classification attribute, then
- Ci) (the value of the attribute Ak is the number of tuples of xk in Ci) / (the number of tuples of Ci in D).
- Classification usually involves two steps: the establishment of the model and the application of the model.
- model a data set that has been identified for a category.
- the data set used to build the model is called the training set, and the single tuple in the training set is called the training sample.
- Each tuple in the training set belongs to a certain category, and the categories are represented by class labels.
- Learning models are provided in the form of classification rules or mathematical formulas. In practice, the number of samples that are known to be classified According to the training set, after learning the training set, the rules about classification are obtained, so that the new data is classified.
- test set refers to a set of independent samples that have not been used in designing the identification and classification system to evaluate the ability of the model to predict, etc., in order to validate the model.
- Figure 2 illustrates a schematic diagram of a scheme 200 for determining a user's age range in accordance with the present invention.
- the scheme for judging the user age segment mainly includes two parts, a model creation and a model application, wherein the model creation includes: the modeling data is split into training data and test data (the ratio is 7:3), and the training data is passed through Nao Subei.
- the Bayesian algorithm generates a Bayesian model, and the test data evaluates the quality of the model through the Bayesian model. By continuously adjusting the features and classification labels, a better model is finally obtained.
- the model application includes, for example, predicting all user data that conforms to the characteristics of the model through the model and finally obtaining a large amount of user age data.
- the final data characteristics the user's third-level category consumption data in the most recent year, the specific modeling data can be shown in Table 1.
- the method and steps for entering a data set are:
- the input data format is shown in Table 2:
- Input data format is shown in Table 4.
- the output data format is shown in Table 5.
