The AI Chatbot with Sentiment Analysis is an advanced Python project that solves a real-world problem using Pre-trained weight checkpoints and GPU-accelerated training pipeline, orchestrated with OpenCV / MediaPipe. It is architected as a modular system where data handling, processing logic, and presentation layers stay cleanly separated, so each part can be developed, tested, and reused independently. The result is a production-grade application that is easy to explain, extend, and present as a final year capstone.
Most existing approaches to this problem rely on manual effort or fragile scripts that are slow, hard to maintain, and unable to scale with growing data. Without an automated, well-structured solution built on GPU-accelerated training pipeline, organizations and students alike struggle to get consistent, reliable results, and there is no easy way to monitor, audit, or improve the process over time.
This project builds an automated, modular system that ingests inputs through Pre-trained weight checkpoints, processes them with OpenCV / MediaPipe, and exposes results through Streamlit / web UI. The design emphasizes maintainability, testability, and reusability, so the same architecture can be adapted to related problems with minimal changes. It delivers consistent results, keeps a clear audit trail, and drastically reduces the manual effort involved.

Clean separation of data, logic, and presentation
The system follows a layered architecture. The data layer handles acquisition and cleaning through Pre-trained weight checkpoints; the logic layer implements the core processing with OpenCV / MediaPipe and GPU-accelerated training pipeline; and the presentation layer exposes results through Streamlit / web UI. A shared configuration module and a logging module support all layers, while the whole system is wrapped with automated tests. This separation makes the project easy to debug, benchmark, and extend.
