Federated learning (also known as collaborative learning) is a machine learning technique in a setting where multiple entities (often called clients) collaboratively train a model while keeping their data decentralized, [1] rather than centrally stored. A defining characteristic of federated learning is data heterogeneity.
The Federated Learning of Cohorts algorithm analyzes users' online activity within the browser, and generates a "cohort ID" using the SimHash algorithm [13] to group a given user with other users who access similar content.
Federated learning is a machine learning technique that trains models across multiple distributed nodes. Each node houses a local, private dataset. Each node houses a local, private dataset. Adversarial stylometry methods may allow authors writing anonymously or pseudonymously to resist having their texts linked to their other identities due to ...
"In the absence of a global authority, the federated architecture has to resolve two conflicting requirements: the components must maintain as much autonomy as possible, but the components must be able to achieve a reasonable degree of information sharing" (Heimbiger, 1985). This is the reason federated architecture strongly demands for governance.
The export schema helps in managing flow of control of data. Federated Schema is an integration of multiple export schemas. It includes information on data distribution that is generated when integrating export schemas. [3] External schema is extracted from a federated schema, and is defined for the users/applications of a particular federation ...
The use of the terminology is in need of clarification. Machine learning is not confined to association rule mining, c.f. the body of work on symbolic ML and relational learning (the differences to deep learning being the choice of representation, localist logical rather than distributed, and the non-use of gradient-based learning algorithms).
Federate: A system, such as a simulation, a tool or an interface to live systems, that connects to the RTI. Examples of tools are data loggers and management tools. A federate uses the RTI services to exchange data and synchronize with other federates. Federation: A set of federates that connect to the same RTI together with a common FOM.
When federated search is performed against secure data sources, the users' credentials must be passed on to each underlying search engine, so that appropriate security is maintained. If the user has different login credentials for different systems, there must be a means to map their login ID to each search engine's security domain.
