The current study aims to present a detailed analysis about stress detection using
data gathered from chatbot as well as data collected from wearables. The main
target is to build a chatbot in order to collect stress related data from employees.
Then predictive models such as Random Forest Classifier and XGBoost are used for
stress classification as well as for burnout prediction. Both cases are converted to
binary classification models using suitable methods. These models are evaluated
using robust metrics such as accuracy, precision, F1-score and confusion matrix.
Moreover, SMOTE algorithm, which is an algorithm for producing synthetic data, is
used in order to achieve class balance and Grid search parameters are used to get
the best parameters for the predictive models. In addition to this, the most impactful
features that are responsible for the presence of burnout are presented in detail.
Regarding the psychological signals collected from wearables, they are used also to
build a pipeline for stress classification. In this case, the two predictive models that
are used are Random Forest Classifier and Support Vector Machines. These models
are also evaluated using the same metrics already mentioned.
