There is a "performance to data" operator, you can connect this to the performance operator and this will help you connect to write excel or CSV operator. But it will save the accuracy and other parameters and not the confusion matrix.
I see that the confusion matrix can be saved using report generation extension, there are two reporting extensions, one is an old one and the new one is "Advanced reporting extension" (3rd Party). This is a paid one but not much expensive if you want to consider (Click_Here).
I tried the free one "Reporting Extension", this is free but old and I don't think it works well, I tried saving as pdf but the confusion matrices are saved in the second page. Sample XML is given below with titanic dataset. You need to have the mentioned extension to run this code.
Hope this helps.

Do we have any document that specifies extensions and their relevant operators? It would be good if there is one.
Thanks

Either we can do text (string) matching in market place, but my concern is it returns lot of operators with that string and may not be feasible. I am thinking something like an excel with extension name and their relevant operator with a one line description if possible. When ever a new extension is created, this should be updates with relevant information.
There may be other efficient ways, need to give some thought on this one.
Thanks

Pretty strange and looks like some connection problem (?)... I personally never had any problem with search on the marketplace:
Same results are achievable also on the marketplace web site: https://marketplace.rapidminer.com/UpdateServer/faces/index.xhtml

There is an approximative solution to extract (in your case) as exampleset via the Performance to Data operator :
- the weighted mean recall
- the weighted mean precision
NB : These performances metrics are initialy calculated by the Performance (Classification) operator inside the CV operator (so you have to check these 2 performance metrics in the parameters of the ¨Performance operator).
Then you can "join" the exampleset with these 2 perf. metrics with the exampleset with your confusion matrix...
The resulting exampleset looks like that : (here for the Iris Dataset) :
The process :

Mmmh, at first sight it is strange (but interesting) ....
I'm considering the picture you shared in your first post :
- accuracy = 46,49 %
- When I average the different class recall in your results (52 %, 46%, 26% etc.) I obtain weighted_mean_recall = 46,49 % (weights = 1, 1,1 etc.) = accuracy.
Anyways to understand what's going on, can you share please :
- your data
- your process (XML)

Lionel
