Generative AI for Personalized Mental Health Recommendations

Sage: Our application uses generative AI to provide personalized mental health recommendations by training a model on diverse mental health data to address individual user needs.

Comment

Inspiration

Our project, "Generative AI for Personalized Mental Health Recommendations," was inspired by the growing need for accessible and individualized mental health support. Recognizing that mental health issues are diverse and deeply personal, we aimed to create a solution that leverages generative AI to offer tailored recommendations and resources. Our goal is to enhance the accessibility and effectiveness of mental health care, providing users with support that is both relevant and responsive to their unique needs.

What It Does

The application provides personalized mental health recommendations using advanced generative AI models. By analyzing user inputs, mood assessments, and behavioral patterns, the platform generates customized coping strategies, resources, and advice. Users receive real-time support that adapts to their changing needs, helping them manage their mental well-being more effectively.

How We Built It

We developed the platform using Fast Api as our back-end framework, ensuring a robust and scalable architecture. The generative AI models were integrated to analyze user data and produce personalized recommendations. We utilized NVIDIA AI Workbench for training and fine-tuning these models, taking advantage of its powerful computational resources. The front-end was designed with a focus on user experience, ensuring that the interface was intuitive and engaging.

Step-by-step

Fine Tuning the Existing Gemma Model

Gemma is a family of lightweight, state-of-the-art open models built from the same research and technology used to create the Gemini models. LLMs are extremely large in size (parameters in the order of millions). Full fine-tuning (which updates all the parameters in the model) is not required for most applications because typical fine-tuning datasets are relatively much smaller than the pre-training datasets. Low Rank Adaptation (LoRA) is a fine-tuning technique which greatly reduces the number of trainable parameters for downstream tasks by freezing the weights of the model and inserting a smaller number of new weights into the model. This makes training with LoRA much faster and more memory-efficient, and produces smaller model weights (a few hundred MBs), all while maintaining the quality of the model outputs.

Building a A Chat Application called Sage using Gradio

Next, I'll be building a chat application using Gradio, an open-source Python package that simplifies creating web applications and demos. Gradio allows easy integration with machine learning models, APIs, or any Python function, making development more efficient.

In this project, we'll use Gradio to run inferences with our fine-tuned model and develop a chat app named Lucy. Lucy will be an AI-powered companion designed to offer support and comfort during times of need. With a user-friendly interface, Lucy will provide meaningful conversations and empathetic responses, making her a reliable source of support for users seeking assistance.
