The sharing of Microsoft’s toys continued today with the open-sourcing of its model-based machine-learning framework, Infer.NET.

A team at Microsoft’s research centre in Cambridge, UK, kicked off development of the framework in 2004, and it was released for academic use in 2008. In Microsoft’s brave new world of AI, the technology has found itself evolving into a machine-learning engine and creeping into Office and Azure as well as gaming applications on Xbox.
