Summary
Federated learning is revolutionizing the way we train large language models (LLMs) by enabling secure, distributed multi-party collaboration. NVIDIA FLARE, an open-source and extensible SDK, is at the forefront of this movement. This article explores how NVIDIA FLARE enhances LLM performance through scalable federated learning, addressing key challenges such as data privacy and resource limitations.
The Challenge of Training Large Language Models
Training LLMs requires vast amounts of data and computing resources, which can be difficult to centralize due to privacy, regulatory, and geopolitical issues. Traditional methods often fall short in managing these complexities, leading to compromised data security and privacy.
What is Federated Learning?
Federated learning is a method that allows AI models to be built and validated from diverse data sources without the data ever leaving the individual site. This approach mitigates the risk of compromising data security and privacy, enabling more accurate and generalizable AI models.
Key Benefits of Federated Learning
- Privacy-Preserving: Federated learning ensures that each change to the global model stays hidden, preventing the server from reverse-engineering the submitted weights and discovering any training data.
- Distributed Collaboration: It enables AI models to be built with a consortium of data providers without the data ever leaving the individual site.
- Scalability: Federated learning allows for both data and model parallelism, leveraging compute resources from multiple locations to train a model shared by all participants.
