What is Federated learning? – A Complete Guide!

Federated learning

The article What is Federated learning? is explaining briefly about Federated Learning. Federated Learning is a part of machine learning. The concept of federal learning is to correct machine learning algorithms while maintaining data privacy and enhancing cybersecurity. This is done by letting machine learning algorithms train and correct themselves from the performance of similar algorithms in other datasets. 

What is Federated learning? – Benefits!

Federated learning actually teaches an algorithm used in machine learning across datasets within local nodes. The principle works by training local models on local data samples and then exchanging parameters between these local nodes.

Federated learning

For instance, as users in a network utilize a machine learning application or algorithm, they can spot errors in the execution caused by the application of the algorithm and do corrections. These corrections serve as local training datasets so that the machine learning now knows and that mistake will not be repeated.

This new learning of that mistake correction now becomes a global model in that data center.

Companies using machine learning extensively and require accurate machine learning techniques rather than conventional machine learning. Conventional machine learning has limitations such as a lack of learning on edge devices.

Moreover, conventional machine learning is built over a common data set and end-user devices most often do not have access to the central dataset. Another problem is that a user’s data accumulates in a central area and may compromise the user’s privacy.

Federated learning takes care of this accessibility by learning from user data while ensuring that the data never leaves the user’s device. 

Federated learning is a popular research topic as more and more unique features are being discovered.

Federated learning, however, is finding wide use in diverse fields such as in predictive maintenance in Manufacturing operations, in smartphones, in health care, and even in automobiles.  

Federated learning is finding wide use in the healthcare field by gathering data from pharmacies, hospitals, laboratories which can be used for finding causes of rare and chronic diseases without compromising remote data from individual data centers in hospitals and clinics, thereby maintaining data privacy while allowing the system to learn from remote experiences.

Federated learning is use in healthcare

Federated learning has made inroads into smartphones from the data pool of millions of handsets and is using this technology in features such as face recognition and voice recognition in newer models and using Federated learning to provide errorproof detection in an area where there is no room for error.

Google is reportedly using Federated learning in its voice-enabled google assistant which performs complex searches based on voice commands. 

Federated learning has wide use in the area of autonomous self-driving vehicles. These vehicles need continuous learning to be able to recognize and learn from real-time traffic and road conditions. The control of the autonomous vehicle needs to be trained to make instant decisions while steering in real-time conditions. 

Federated Learning has solved a problem in the manufacturing industry where conservative organizations do not like to share data for fear of competition. Predictive maintenance is a vital part of five crucial types of maintenance and a key ingredient of Total Productive Maintenance (TPM).

The factory system is required to predict the precise moment when key equipment requires maintenance, thereby saving a lot of money in unnecessary breakdowns. Federated learning gathers data on equipment performance over thousands of similar components and learns. Federated learning is thereby able to translate this learning into accurate predictive Maintenance schedules.

There are many advantages of Federated learning. There is now no need to collate or collect data for continual learning as models are being constantly improved using client data. There are savings on investment in hardware as federated learning models do not need large servers for their data analyses. Federated learning also has the advantages of data security and data diversity

Federated learning can be centralized, decentralized, or heterogeneous. Centralized Federated learning makes use of a central server whereas connected nodes coordinate the learning process between themselves using a global model.

In the heterogeneous model of Federated learning, several heterogeneous clients such as mobile phones and appliances connected to the internet of things are able to develop while learning. In fact, the HeteroFL has been developed to train several clients and produce a single inference model. 

The learning process of Federated learning follows the process of initialization, client selection, Configuration, reporting, and termination.
