Early adaptation on the bridge between research and the real world

Federated learning is a relatively new technology, and it is still in the process of being adopted by different industries. First mover are digital technology companies, certain public institutions, automotive, space, healthcare and universities. There are already several examples of companies and organizations using FL to improve their products and services, and it's not surprising that they are the top data companies in the world:

  • Google: Google has been one of the pioneers in FL, using it to improve the performance of its keyboard app, Gboard. The app uses FL to train a model on the typing patterns of individual users, making predictions more accurate and reducing the amount of data that needs to be sent to a central server.
  • Apple: Apple has also been exploring FL, using it to improve the performance of its Siri voice assistant. The company has been using FL to train a model on the speech patterns of individual users, making Siri more accurate and responsive.
  • OpenAI: OpenAI has been working on FL to improve the performance of its GPT-3 model. The company has been using FL to train a model on the data of individual users, making the model more accurate and personalized.
  • Alibaba: Alibaba has been using FL to improve the performance of its recommendation system. The company has been using FL to train a model on the browsing and purchasing habits of individual users, making recommendations more accurate and personalized.
  • Meta: Facebook has been using FL to improve the performance of its text classification system. The company has been using FL to train a model on the text data of individual users, making the model more accurate and personalized.
  • NASA / ESA: FL is used to interpret, classify, and search multiple satellite images for a variety of projects, the most prominent of which is the Earth Observation Project. The Technical University of Berlin leads a number of ESA research groups working on such platforms.

It is safe to say that FL is a rapidly evolving field that is expected to become more widely adopted in the industry in the coming years as businesses and organizations realize the benefits it can bring in terms of performance, privacy, and scalability.

Commercial use of Federated Learning

There are several ways in which Federated Learning (FL) can be used in enterprise settings to improve business operations and decision making. Here are a few examples:

  • Personalization: By training a model on the data of individual customers, an enterprise can personalize products and services to meet the specific needs of each customer. For example, a retail company could train a model on the browsing and purchasing habits of each customer and use the model to make personalized product recommendations.
  • Predictive maintenance: By training a model on sensor data from equipment, an enterprise can predict when maintenance is needed and schedule it before a failure occurs. This can increase uptime and reduce costs.
  • Fraud detection: By training a model on transaction data, an enterprise can detect fraudulent activity and take action to prevent it. This can reduce financial losses and improve customer trust.
  • Image and video analysis: By training a model on image and video data, an enterprise can improve object detection and tracking, as well as facial recognition. This can be used in areas such as security, surveillance and self-driving cars.
  • Edge computing: By training a model on data collected at the edge of a network, an enterprise can improve the performance and responsiveness of IoT devices, as well as reduce the amount of data that needs to be sent to a central server.

It's important to know that FL can be used in conjunction with other machine learning techniques and technologies, such as cloud computing, big data platforms, and deep learning. As well as considering the technical aspects, it's also important to take into account the organizational, legal and ethical issues related to using FL in an enterprise setting.

Open Source projects for Federated Learning

There are several open-source Federated Learning (FL) projects that have been developed to make it easier for researchers and developers to experiment with FL and build their own FL systems. Here are a few examples:

  • TensorFlow Federated (TFF): TFF is an open-source library for building FL systems using TensorFlow. It provides a set of APIs and tools for training models on federated data, as well as for implementing various FL algorithms.
  • PySyft: PySyft is an open-source library for building FL systems using PyTorch. It provides a set of APIs and tools for training models on federated data, as well as for implementing various FL algorithms.
  • OpenMined: OpenMined is an open-source community focused on developing tools and libraries for privacy-preserving machine learning, including FL. It provides a set of libraries and tools for building FL systems, as well as tutorials and resources for learning about FL.
  • PaddleFL: PaddleFL is an open-source FL platform developed by Baidu which provides a set of tools and libraries for building FL systems, as well as a set of pre-built models and datasets.
  • Apache Wayang (incubating): Apache Wayang is an open-source project that provides a set of libraries and tools for building FL systems. It aims to provide a common framework for FL developers, enabling them to create efficient, secure, and reliable FL systems.
  • FL-Core: FL-Core is a lightweight, open-source, and easy-to-use framework for Federated Learning (FL) written in Python. It supports data parallelism and model parallelism, and makes it easy to build custom FL workflows.
  • Leabra: Leabra is an open-source library for building neural networks and other machine learning models. It provides a set of tools and libraries for building FL systems, as well as a set of pre-built models and datasets.

These are just a few examples of open-source FL projects, and new ones are appearing regularly. These projects can be a great resource for researchers and developers who want to learn more about FL or build their own FL systems.

The future of Federated Learning and decentralized AI training

We at databloom.ai are the largest contributor to Apache Wayang (incubating), which undergoes a graduation process at the Apache Software Foundation. Wayang is a federated data processing platform that provides a set of libraries, APIs, and tools for building and deploying FL systems. The goal of Wayang is to provide an easy-to-use and extensible data framework, allowing developers to create efficient and reliable data processing systems with minimal effort. By supporting data parallelism and model parallelism, as well as various types of communication between clients and servers, Wayang also aims to provide a secure and privacy-preserving solution by supporting a secure multiparty computing environment. Wayang is expected to be a valuable resource for developers looking to build FL systems, providing an easy-to-use and extensible framework for creating efficient, secure, and reliable FL systems.

Federation addresses several key challenges in machine learning; we talked about data privacy, data regulations, scalability, and performance. One of the biggest upcoming use cases for FL is IoT, the Internet of Things, and therefore edge computing. FL can be used to train models on data collected by IoT devices and stored in small, efficient edge devices with limited ML capabilities. Using FL in large IoT and edge system setups, like smart cities, autonomous driving, or space-related projects like the Earth Observation Project, federated AI and data processing improves the performance and responsiveness of devices, as well as reducing the amount of data that needs to be transferred to central systems, be they data warehouses or data lakes. FL is also expected to play a major role in the development of autonomous systems, such as self-driving cars, drones, and robotics, where the technology can be used to train models on the data collected by the systems, making them more accurate and reliable. In addition, federated learning is also expected to be used in a wide range of other industries and applications, such as healthcare, finance, and manufacturing.
