⚙️What is FL ?
Federated Learning (FL) is a machine learning technique that allows multiple devices or nodes to collaboratively train a model without sharing their local data.
Instead of sending data to a central server, each node processes the data locally and shares only the model updates (like weights and biases). This approach has several advantages, especially when privacy and data security are priorities.
How Federated Learning is Changing the World
Federated Learning is revolutionizing the way machine learning models are built and deployed by enabling decentralized collaboration. Traditional machine learning requires aggregating data in one place, which can lead to privacy concerns, data breaches, and compliance challenges. FL changes this paradigm by allowing local data processing and sharing only the model updates, thereby:
Preserving Privacy: Data remains on local devices, ensuring compliance with privacy regulations and reducing the risk of data breaches.
Enhancing Security: Since raw data is never transmitted over the network, FL minimizes exposure to potential cyber threats.
Enabling Collaboration Across Organizations: Different organizations can collaborate on model development without sharing sensitive data, fostering innovation while maintaining data privacy.
Supporting Edge Computing: With the rise of smart devices and IoT, FL allows models to be trained directly on devices, reducing latency and the need for constant connectivity.

A Global Collaboration Without Sharing Raw Data
With FL, hospitals across continents can collaborate on training an AI model without transferring raw patient data. Each hospital keeps its data secure and local, while FL allows the model to learn directly from their datasets.
• Imagine ten hospitals, each training a part of the model on their own data.
• The learned insights—encrypted model updates, not raw data—are shared with a central server or blockchain network.
• These encrypted updates are aggregated to improve the global model without ever exposing sensitive information.
Privacy-Preserving with Advanced Cryptography
Using cryptographic techniques like Pedersen commitments, FL ensures that Medical histories remain confidential: No raw data is ever shared outside the hospital’s servers.
Encryption protects all communication: Weights, biases, and updates are secure from end to end.
Regulations are adhered to: FL enables hospitals to comply with data privacy laws while still participating in groundbreaking research.
Faster, Smarter Insights Without Risk
Through this decentralized collaboration - AI models are trained on a diverse, global dataset, ensuring they are more accurate and effective.
Hospitals don’t need to spend months negotiating data-sharing agreements—they can start contributing instantly.
And, Patients benefit from faster diagnoses, personalized treatments, and ultimately, better chances of survival.
