This document describes a project to predict mental fitness using machine learning regression models. The project will use parameters like schizophrenia, bipolar disorder, anxiety, depression, drug usage, and alcohol usage to predict an individual's mental fitness score. A random forest regressor is used as the machine learning model. The model is trained on datasets from online sources. Evaluation metrics like mean squared error indicate the model performs well. Potential end users are medical centers and researchers. The project was implemented from scratch using Python libraries like Pandas, Scikit-Learn, and Seaborn.
