It might be from their own mind for gaining more & more intheir Academics or might be from Parental Pressure. Accurate analysis and prediction of stress patterns may be possiblewith the use of machine learning techniques and enabling prompt responses. With an emphasis on the function of machinelearning models, the influence of physiological and behavioral characteristics, this paper explores the important facets ofmental stress detection. The search was conducted on several databases (IEEE, Scopus, Elsevier, and Web of Science).Thetopmost objective of the paper is to analyze various algorithms that are used to predict the level of stress among an individual.This Review paper is based on the analysis of various approaches and finally gives the most appealing among all. RandomForest & Gradient Boosting are the best algorithm with topmost accuracy that has been used in various papers and alsohelps in accurately predicting the level of stress among the individual.
