specific Embodiment 1
[0078] Specifically, this embodiment provides a data prediction analysis method for the China General Social Survey (CGSS) data set. CGSS aims to systematically monitor the relationship between social structure and quality of life in China, and this example evaluates the effectiveness of predictive analysis by exploring the relationship between personal income and other factors.
[0079] This example chooses to analyze the 2015 CGSS dataset, which contains 10968 data samples collected from 10968 individuals. In this embodiment, 45 attributes that may be related to personal income are selected from the CGSS data set.
[0080] After preprocessing the collected data, use the rule fitting algorithm to generate the corresponding rules, assuming that the following four rules are generated:
[0081] Rule 1, the correlation between personal education level and annual income is the most obvious;
[0082] Rule 2, populations with at least secondary education and living in urban areas ...

[0097] In the expert reasoning system for engineering equipment development, the predictive analysis method of big data is used to collect and analyze data of 8 different types of combat engineering vehicles. as followed:
[0098] A1 represents fuel consumption {more, less};
[0099] A2 represents workload {large, medium, small};
[0100] A3 represents the protective ability {strong, weak};
[0101] A4 represents the combat comprehensive performance evaluation index, with 0 and 1 representing low and high decision-making attributes, respectively.
[0102] The information table is shown in Table 1.

specific Embodiment 3
[0126] We can also apply the decision tree model to the traffic field, by analyzing data about road and intersection conditions, traffic conditions, traffic load, traffic control and management, etc., to predict traffic delays and services at urban intersections Level, use the observed data on green signal ratio, saturation, traffic capacity and service level as training samples to train the decision tree model, and use the trained model to predict and analyze the service level of road intersections.
[0127] Specifically, its implementation is as follows:
[0128] P1. Collect data and get data sets; we can collect data about road and intersection conditions, traffic conditions, traffic load, traffic control and management, etc., and integrate them into a data set.
[0129] P2. Preprocess the data set to obtain the interaction between the original attributes of the data in the data set; for example, extract numerical values including green signal ratio, saturation, traffic c...
