PMML is the leading standard for statistical and data mining models and supported by over 30 vendors and organizations. With PMML, it is easy to develop a model on one system using one application and deploy the model on another system using another application, simply by transmitting an XML configuration file.
PFA is an emerging standard for statistical models and data transformation engines. PFA combines the ease of portability across systems with algorithmic flexibility: models, pre-processing, and post-processing are all functions that can be arbitrarily composed, chained, or built into complex workflows. PFA may be as simple as a raw data transformation or as sophisticated as a suite of concurrent data mining models, all described as a JSON or YAML configuration file.
The Data Mining Group is a consortium managed by the Center for Computational Science Research, Inc., which is an Illinois based 501(c)(3) not-for-profit corporation
