The integrated use of Machine Learning (ML) and Business Rules (BR) is one of the most practical trends in the development of modern decision-making software. OpenRules is involved in this development for more than 10 years starting with our successful ML+BR projects for IRS.

OpenRules at AWS

We are aggressively making OpenRules-based services available from cloud environments such as Amazon EC2.

Another example is the game “Nim” that you may play now from the cloud by clicking on the image below: Continue reading
