Key Questions Answered
What is federated learning and how does it work?
Federated learning (FL) is a decentralized approach to training models where clients train on their local datasets and share only model updates, preserving data privacy. This method allows for the aggregation of knowledge from diverse sources without centralizing sensitive data.
What are the differences between supervised fine-tuning and parameter-efficient fine-tuning?
Supervised fine-tuning (SFT) involves adjusting all parameters of a model, while parameter-efficient fine-tuning (PEFT) focuses on adding adaptation parameters or layers to a fixed model. PEFT is often more resource-efficient and cost-effective than SFT.
How does NVIDIA FLARE facilitate scalable model training?
NVIDIA FLARE supports scalable model training through features like the Lightning Client API and the ability to stream large files, which helps in managing the substantial data transfer required for training large language models effectively.
What performance improvements can be expected from using federated learning?
Federated learning can enhance model performance by allowing the aggregation of updates from multiple clients, resulting in better accuracy and robustness compared to training on isolated datasets. This collaborative approach leverages larger and more diverse datasets.

Common Pitfalls
1
Failing to properly manage data privacy during model training.
Without federated learning, organizations risk exposing sensitive data when centralizing datasets for training, which can lead to compliance issues and loss of user trust.
2
Overlooking the resource implications of supervised fine-tuning.
SFT requires significant computational resources, which may not be feasible for all organizations. Parameter-efficient approaches should be considered to mitigate this challenge.
