Salesforce just bought another startup in the machine learning space

Salesforce just agreed to buy a small startup called PredictionIO, a software maker that helps developers build predictive applications. The announcement was made through PredictionIO's blog post. The exact terms of the deal were not disclosed. PredictionIO's website says it's a maker of open source software for machine learning apps. That means anyone could use or modify the designs of its software to build an app that does a lot of data analytics and predictive work.
