Best Practice
Federated Learning
Unlock the potential of your data – without giving it away.
Shared intelligence, secured data
In hospitals, banks, factories, and beyond, valuable data is generated every day – but much of it goes untapped. Strict data protection laws, regulatory demands, and concerns about data security often prevent organizations from fully leveraging artificial intelligence. Federated learning is changing that.
Federated learning is an approach to Machine Learning in which AI models are trained in a decentralised manner – directly where the data is generated. The data remains on local devices or in protected systems. Only the trained model parameters are centrally consolidated and evaluated. This enables joint learning across system or company boundaries without ever having to share sensitive data.
Federated Learning as the key to privacy-compliant progress
With its versatility, federated learning finds practical use in numerous areas. Wherever sensitive data is distributed across different parties, this approach creates new opportunities – without compromising security.
Healthcare
Hospitals, labs, and research institutions can collaboratively train AI for disease detection, diagnosis, and treatment – for example, identifying tumors or personalizing care for chronic illnesses. Patient data always stays on-site, enabling innovation without privacy compromise.
Financial sector
Banks operate under strict regulations and face constant cybersecurity threats. Federated Learning allows them to detect fraud, money laundering, or credit risk collectively – without ever sharing customer data. Each bank trains locally, while the model learns globally.
Automotive industry
Modern vehicles generate enormous volumes of sensor data. Federated Learning enables manufacturers to improve driver assistance, optimize maintenance, and advance autonomous driving – all without centralizing sensitive user information. The fleet learns together while keeping data in place.
Retail & e-commerce
Understanding customers is essential for success. With Federated Learning, retailers can train AI for recommendations, inventory planning, and dynamic pricing directly on POS systems or in apps. Sensitive data, such as purchase history and location, remains private – while AI personalizes the experience.
Public sector & smart cities
From traffic flow to energy grids, the city of tomorrow runs on data. Federated Learning empowers governments, utilities, and transport providers to collaborate securely – driving innovation without merging datasets or exposing systems.
Manufacturing & Industrial IoT
Factories and industrial systems generate massive amounts of sensor and machine data. With federated learning, companies can optimize predictive maintenance, quality control, and energy efficiency – without moving data off-site. Each machine or plant contributes to smarter models while keeping operational data secure.
Cross-industry collaboration
Federated Learning opens the door for entirely new forms of collaboration. For example, hospitals and insurance providers can train models together to predict treatment outcomes or assess patient risk – without ever exchanging sensitive data. This creates shared value across sectors while maintaining strict data protection.

Federated Learning and local LLMs – an unbeatable team
In this context, local LLMs are gaining in importance: language models that run directly on company-owned systems, ensuring maximum data sovereignty. Combining both approaches allows LLMs to be adapted locally with confidential data and improved collaboratively via Federated Learning – securely, efficiently and scalably. Modern methods such as Parameter-Efficient Fine-Tuning (PEFT) or model compression make this interaction possible even with limited resources. The result: continuously learning, personalised AI models with full control over the data.
