Call for Contributions

How to Get Involved

  • Propose Solutions: Contribute new algorithms, utilities, or examples to advance federated learning.

  • Define Your Approach: Write a short proposal outlining the problem and why it matters. Include your proposed method, how it improves federated learning, expected outcomes, and benefits (e.g., improved efficiency, reduced communication overhead, enhanced privacy).

  • Register Your proposal: Use the link above.

  • Engage With the Community: Discuss ideas, collaborate, and get feedback on implementation.

Why Participate?

  • Gain Recognition. Select contributors will be invited to present their work at NVIDIA FLARE Day 2025.

  • Make an Impact. Help solve key challenges in federated learning.

  • Collaborate With Experts. Work with researchers, developers, and industry professionals.

Focus Areas

We welcome contributions in the following areas:

  • Energy-Efficient Communication and Learning
    E.g., compression, pruning, parameter-efficient fine-tuning, asynchronous federated learning (FL), and carbon footprint tracking.

  • Privacy-Preserving Techniques in the Age of LLMs
    E.g., differential privacy, memorization prevention, privacy attacks, and defenses.

  • Training on the Edge (Real-Time and Multi-Sensor Data)
    E.g., mobile, automotive, robotics, surgery, and dynamic sensor networks.

  • Collaborative Inference and Information Aggregation
    E.g., federated retrieval-augmented generation (RAG), multi-agent learning, decentralized inference.

Contribution Types

We're looking for the following contributions:

  • Algorithms: Novel methods to improve federated learning efficiency, scalability, and security

  • Core Framework and Utilities: Enhancements to NVFlare’s core functionalities

  • Examples and Use Cases: Demonstrations of FL applications in real-world scenarios
