how to get the model description

How can I log the output from our models?
I took the training and learned how to log model parameters and  model performance. But I am also interested in get information about the actual model, for the description tab in the model output, I wish I could attach an image of what I am trying to say....

    Hi senniang,

    You can store the model itself as well. Than you can have a look in the repository. Or do you want to store e.g. the decision tree as an png on hard disc?

    Best,

    Hi Senniang,

    I think you mean the model text description in the results window. 
    Method 1: Use RapidMiner Server
    If you are using RapidMiner Server then create a webservice or reporting component a process that returns the model you want to build. 
    Next choose Output = HTML & select either "text/html" or "text/plain" as the MIME type. 

    Method 2: If you don't have RapidMiner Server and want to extract the details through RapidMiner Studio.

    Whilst I believe you can get at this through the Execute Script operator I confess that I haven't tried & don't want to give you any untested methods. 
    One easy way to access this then is to install the reporting extension and then export the information you want as part of your report.
    See below process for an example. 
    (please note: Method 1 is much easier IMO)

    Thank you all for the help. I want to get the model description for the next step computation. I want to be able to automate the process. Is there any operator that allows me to write the model into an excel or a data table in RM?
