How to use machine learning to increase information systems value ?

Look into Big data if your IS data is consuming a ZB or more. Otherwise look into data mining and data warehousing. 

Well machine learning is the present and the future. How they can increase the information systems value is dependent on your use. 

as models are exposed to new data, they are able to independently adapt. They learn from previous computations to produce reliable, repeatable decisions and results. It’s a science that’s not new – but one that’s gaining fresh momentum.
