In the centralized federated learning setting, a central server is used to orchestrate the different steps of the algorithms and coordinate all the participating nodes during the learning process. The server is responsible for the nodes selection at the beginning of the training process and for the aggregation of the received model updates.
Federated architecture. Federated architecture (FA) is a pattern in enterprise architecture that allows interoperability and information sharing between semi-autonomous de-centrally organized lines of business (LOBs), information technology systems and applications. Architecture areas of concern. Organisational architecture; Business architecture
A DBMS can be classified as either centralized or distributed. A centralized system manages a single database while distributed manages multiple databases. A component DBS in a DBMS may be centralized or distributed. A multiple DBS (MDBS) can be classified into two types depending on the autonomy of the component DBS as federated and non federated.
Difference between centralized federated learning (on the left) and decentralized federated learning (on the right) French Illustration de la différence entre apprentissage fédéré centralisé (à gauche) et apprentissage fédéré décentralisé (à droite)
The two broad types of architecture, centralized and federated, correspond to the data warehouse and federated database system models of data integration. In the centralized configuration (e.g., The Santa Cruz Community and the Michigan UP Network), all providers send their data to the RHIO's central repository on a periodic basis (daily).
Accordingly, the idea of a strong, centralized government has very negative connotations in German politics, although the progressive political movements in Germany (Liberals, Social Democrats) were advocating at the time of the Second German Empire (1871–1918) to abolish (or to reshape) the majority of German federated states of that era, as ...
The Electronic Frontier Foundation (EFF), a U.S. legal defense organization and advocacy group for civil liberties on the Internet, endorses the distributed social network model as one "that can plausibly return control and choice to the hands of the Internet user" and allow persons living under restrictive regimes to "conduct activism on social networking sites while also having a choice of ...
With federated learning coupled with local differential privacy, researchers have found this model to be quite effective to facilitate crowdsourcing applications and provide protection for users' privacy. Federated learning has the ambition to protect data privacy through distributed learning methods that keep the data in its storage. Likewise ...
