Abstract

Job satisfaction is the attitude or feelings of employees towards the pleasant or unpleasant aspects of work that in accordance with the assessment of each employee. There are several factors that affect job satisfaction, such as work environment satisfaction and employees' welfare. With obtained datasets, ‘welfare satisfaction’ and ‘environment satisfaction’ were used as independent variables with project numbers as dependent variables to examine an algorithm indicating the highest accuracy with the lowest RMSE and MAE values and the highest R-Squared values out of four algorithms, namely Linear Regression, Support Vector Regression, AdaBoost Regression, and Random Forest Regression. The results suggested that Random Forest Regression was the most accurate algorithm with MAE and RMSE values of 0.097000 and 0.185068, respectively, and R-Squared values of 0.981878.
几种预测工作满意度的回归算法比较
工作满意度是员工对工作中愉快或不愉快方面的态度或感受,与每个员工的评估相一致。影响工作满意度的因素有几个,如工作环境满意度和员工福利。利用获得的数据集,“福利满意度”和“环境满意度”被用作自变量,项目编号作为自变量,以检验一种算法,该算法表明线性回归、支持向量回归、AdaBoost回归和随机森林回归四种算法中具有最低RMSE和MAE值以及最高r平方值的最高精度。结果表明,随机森林回归是最准确的算法,MAE和RMSE分别为0.097000和0.185068,R-Squared值为0.981878。
