This document proposes a system to detect depression from users' online posts through machine learning. It would analyze text, images, and audio uploaded by users to social media platforms. If the system detects depressive language or content, it would send motivational messages to the user. The system would use support vector machines trained on labeled data and natural language processing techniques to classify posts as indicating depression or not. It aims to help identify depressed users and provide support by analyzing common language patterns associated with mental illness.
