| description | This study compared various machine learning methods to develop an accurate predictive
system to predict perceived stress in regression problem with relevant personality traits.
The machine learning methods that were identified and being compared including the
single regression models (Multiple Linear Regression, Support Vector Machine for
regression, Elastic Net, Random Forest, Gaussian Process Regression, and Multilayer.
Perceptron), homogeneous ensemble models (Bagging, Random Subspace, and Additive
Regression), and heterogeneous ensemble models (Voting and Stacking). The dataset for
the training and testing the predictive methods was taken from a study which the survey
was distributed to the public in Melbourne, Australia and its surrounding districts. The
selected predictors for perceived stress include gender and six personality traits, namely;
mastery, positive affect, negative affect, life satisfaction, self-esteem, and perceived
control of internal states. The predictive performances of all the predictive methods were
compared, and the benchmark single model was identified. The ensemble instances with
certain combinations of single models as base learners and with certain meta learners
were proven to perform better than the benchmark single model. The implications and
recommendations were discussed in this study.
