Introduction: A Powerful Engine Empowering Cutting-Edge AI Research
As Generative Artificial Intelligence (Generative AI) drives transformation across various fields at an unprecedented pace, having efficient, scalable, and flexible development tools is crucial for research institutions. The training, fine-tuning, and deployment of advanced AI technologies like Large Language Models (LLMs) and Multimodal Models (MMs) require robust underlying frameworks to cope with ever-increasing model sizes and data complexity.
BIT Research Alliance consistently stands at the forefront of AI technology application. To rapidly translate our innovative ideas in fields like healthcare into tangible results, we have chosen and deeply integrated the NVIDIA NeMo™ framework. This end-to-end, cloud-native framework provides us with a comprehensive suite of tools and capabilities needed to develop, customize, and deploy large-scale Generative AI models.

How BIT Research Alliance Leverages the NeMo™ Framework to Accelerate Innovation
The NVIDIA NeMo™ framework plays an indispensable role in various research projects at BIT Research Alliance:
- Rapid Prototyping and Model Iteration:
- NeMo’s pre-trained models and standardized training workflows enable us to quickly build and test new AI model concepts, shortening the cycle from idea to initial validation.
- For example, when developing language models for specific medical texts, we can leverage NeMo’s LLM foundation models and efficiently fine-tune them with our collected medical corpora.
- Handling Large-Scale, Multimodal Medical Data:
- Data in the medical field is often massive and multimodal. The NeMo framework’s data processing and multimodal model support capabilities help us effectively manage and utilize this complex data.
- In our projects like the multimodal chronic disease management framework or AI food recognition, the NeMo framework has supported the joint processing and model training for various data types, including images and text.
- Achieving Efficient Model Customization and Alignment:
- For specific medical application scenarios (such as diagnostic assistance for particular diseases or health guidance for specific populations), we need to customize general models. Parameter-efficient fine-tuning techniques like LoRA, provided by NeMo, allow us to quickly adapt models with limited data and computational resources.
- Simultaneously, through alignment techniques like RLHF (Reinforcement Learning from Human Feedback), we can guide models to generate content that better conforms to medical professional standards and ethical requirements.
- Optimizing Deployment and Inference Efficiency:
- Efficient deployment and inference are crucial for translating research outcomes into practical medical AI tools. The NeMo framework, combined with TensorRT-LLM™ and NVIDIA Triton™ Inference Server, optimizes trained models and deploys them as high-performance inference services, meeting the real-time demands of clinical applications.
- This is particularly important in our development of Line chatbots requiring real-time responses or edge computing AI systems.
- Ensuring Reliability and Safety of AI Applications:
- The reliability and safety of medical AI are our top priorities. NeMo Guardrails allow us to set clear behavioral boundaries for AI models, preventing them from generating inaccurate, irrelevant, or harmful content, thereby enhancing the trustworthiness of our AI solutions.
The Value the NeMo™ Framework Brings to BIT Research Alliance
Integrating the NVIDIA NeMo™ framework has brought multifaceted value to BIT Research Alliance:
- Increased R&D Efficiency: Significantly shortens the development, training, and optimization time for AI models.
- Enhanced Model Performance: Enables the training of larger, more complex, and higher-performing Generative AI models.
- Lowered Technical Barriers: Standardized tools and workflows make it easier for our researchers to master advanced AI technologies.
- Accelerated Translation of Results: More quickly transforms cutting-edge AI research outcomes into solutions that can address real-world medical problems.
