MOA and WEKA are powerful tools to perform data mining analysis tasks. Usually, in real applications and professional settings, the data mining processes are complex and consist of several steps. These steps can be seen as a workflow. Instead of implementing a program in JAVA, a professional data miner will build a solution using a workflow, so that it will be much easier to maintain for non-programmer users.
The Advanced Data mining And Machine learning System (ADAMS) is a novel, flexible workflow engine aimed at quickly building and maintaining real-world, complex knowledge workflows.
The core of ADAMS is the workflow engine, which follows the philosophy of less is more. Instead of letting the user place operators (or actors in ADAMS terms) on a canvas and then manually connect inputs and outputs, ADAMS uses a tree-like structure. This structure and the control actors define how the data is flowing in the workflow, no explicit connections necessary. The tree-like structure stems from the internal object representation and the nesting of sub-actors within actor-handlers.
