Prediction of College Students’ Employment Rate Based on Gray System

Abstract: College students’ employment is affected by many factors such as economy and policy, which makes the prediction error of college students’ employment rate large. In order to solve this problem, a prediction method of college students’ employment rate based on the gray system is designed. Firstly, it analyzes the current research status of college students’ employment rate prediction, finds out the causes of errors, then collects the historical data of college students’ employment rate, fits the change characte… Show more

“…From the point of view of the gray system, the waterborne transport safety production system can be regarded as a "gray box", and its behavior is the gray output generated under the action of a certain gray input. In the prediction of the waterborne transport safety production situation, in order to adapt to the characteristics of "small samples and poor information", overcome the uncertainty of understanding of objective things and the inconclusiveness of statistical information, etc., the parameters and measured data in the waterborne transport safety production situation prediction model can be regarded as gray, and the gray system method is used to identify the gray parameters and monitor and predict waterborne transport safety [10] .…”

“…Then, a model named GM-BPNN (Gray model-BP neural network) of subjective employment obstacles of college students and its predictive factors were constructed based on deep learning, and the results show that the relative error of the combined model is smaller and its accuracy is higher. Yao et al [26] pointed out that many factors can affect college students' employment, so the prediction error of employment rate is usually high. In their work, the authors designed a prediction method for the said problem based on gray system.…”
