This article aims to address the challenge of predicting the salaries of college graduates, a subject of significant practical value in the fields of human resources and career planning. Traditional prediction models often overlook diverse influencing factors and complex data distributions, limiting the accuracy and reliability of their predictions. Against this backdrop, we propose a novel prediction model that integrates maximum likelihood estimation (MLE), Jeffreys priors, Kullback-Leibler risk function, and Gaussian mixture models to optimize LSTM models in deep learning. Compared to existing research, our approach has multiple innovations: First, we successfully improve the model's predictive accuracy through the use of MLE. Second, we reduce the model's complexity and enhance its interpretability by applying Jeffreys priors. Lastly, we employ the Kullback-Leibler risk function for model selection and optimization, while the Gaussian mixture models further refine the capture of complex characteristics of salary distribution. To validate the effectiveness and robustness of our model, we conducted experiments on two different datasets. The results show significant improvements in prediction accuracy, model complexity, and risk performance. This study not only provides an efficient and reliable tool for predicting the salaries of college graduates but also offers robust theoretical and empirical foundations for future research in this field.
本文旨在应对预测大学毕业生薪资这一挑战,该主题在人力资源和职业规划领域具有重大实用价值。传统预测模型常常忽视多样的影响因素和复杂的数据分布,限制了其预测的准确性和可靠性。在此背景下,我们提出一种新颖的预测模型,该模型整合了最大似然估计(MLE)、杰弗里斯先验、库尔贝克-莱布勒风险函数和高斯混合模型,以优化深度学习中的长短期记忆(LSTM)模型。与现有研究相比,我们的方法有多项创新:第一,通过使用最大似然估计成功提高了模型的预测准确性。第二,应用杰弗里斯先验降低了模型的复杂性并增强了其可解释性。最后,我们使用库尔贝克-莱布勒风险函数进行模型选择和优化,而高斯混合模型进一步优化了对薪资分布复杂特征的捕捉。为验证我们模型的有效性和稳健性,我们在两个不同数据集上进行了实验。结果表明,在预测准确性、模型复杂性和风险性能方面有显著提升。本研究不仅为预测大学毕业生薪资提供了一个高效可靠的工具,也为该领域未来研究提供了坚实的理论和实证基础。
