Extract Metadata /Parameters of a whole Process / an experiment?

Sure,

Generate Data by User Specification and then create an example set with your settings. This can be written to any format.

ok I will try that out, is there any way to comment or annotate folders (e.g those with experiments) with additional information provided by yourself? I thought this was a function that was present in previous RapidMiner commercial programs..?

Or is it somehow possible to visualise other files, like normal text files in your folders? where you could save all experiment settings and take a quick glimpse onto it?

EDIT: this is really headachingly painful if you have to enter every parameter and its settings manually for each experiment again.. isn't there a way to do this automatically?

I think it would be really useful if programmers would work this out, e.g for each experiment, do an automatic listing of the operators used, with it's settings in a table-like styled format...

this could be  done by an interface method that will be implemented by each operator or in the main menu, that takes the settings from it's implemented operators, I think that would be easy to implement..

can you explain to me, how I can extract my Parameters settings from the optimize Parameters (GRid) operator, like e.g all the C and gamma values that I chose as combinations? I didnt find how with param("...","...") there seems not to be a field list that accepts those parameter choices to display... ?

Inside your grid opitimizer, you can add an operator 'Log' after the performance.

Hope that makes sense.

this whole concept is overly complicated, for some things I have to use generate  data by user specification, and for some I have to use the log operator, however it gives me just the combinations of all tried out C and gammas, but I want the range of C and gamma that I have configured in grid optimizer, to have an overview of how my process is designed .. the "metadata".

However, to save the results I then have to transform log into an example set and so on -.-

this is really annoying, I think if there would be some way to integrate process creation metadata with more operators into the process context, or enter the operator data directly into the context for additional operators (like split data, sample... etc.) and save your config as an overview of the whole process, this would make it a lot easier.

I could imagine that other data mining tools are capable to save process metadata configuration as well...

Fred,

if it is only the context, you should be fine by parsing the process XML?

I dont know how to parse XML

Static parameters can be extracted by the Generate User Data operator, whilst dynamic parameters like performance that you get when running the process can only be extracted by the Log operator... I will have to convert both into an example set and join them I somehow I guess... or write them onto a separate excel file and append them after...
