Federated machine learning based browser extension

A computer-implemented method, comprising:

• sending, by a system comprising a processor to a web browser extension, a base targeted offer model, wherein the base targeted offer model has been generated based on federated machine learning applied to past web browsing data representative of past web browsing history associated with other web browser extensions other than the web browser extension;
• receiving, by the system from the web browser extension, an updated targeted offer model, wherein the updated targeted offer model is generated by the web browser extension based on success data representative of a level of success of the base targeted offer model according to a success criterion, and based on the base targeted offer model;
• and
• aggregating, by the system and using the federated machine learning, the updated targeted offer model with other updated targeted offer models, other than the updated targeted offer model, associated with other web browser extensions other than the web browser extension, resulting in an aggregated base targeted offer model.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

• using a base targeted offer model and web browsing data, representative of web browsing history based on activity associated with a web browser extension, generating a targeted offer, wherein the base targeted offer model has been generated based on federated machine learning applied to past web browsing data that are representative of past web browsing history associated with other web browser extensions other than the web browser extension;
• based on success data representative of a level of success of the base targeted offer model, according to a success criterion, and based on the base targeted offer model, generating an updated targeted offer model;
• and
• transmitting the updated targeted offer model to an external server, wherein the transmitting the updated targeted offer model does not transmit the web browsing data.
