"Support Vector Machine - Plot View Missing"

Q-Dog

Hello everybody,

I just wanted to implement a simple Support Vector Machine in RapidMiner and noticed that many of the options in the results view were missing.

I only have:
- Text view
- Annotations

According to the online tutorial (and some videos) there should be:
- Text view
- Weight Table
- Support Vector Table
- Plot View
- Annotations

what am I doing wrong? And can you reproduce this behaviour?

Cheers Q-Dog

It sounds like you're only outputting the model itself, not an application of the model to your data nor performance measures thereof.

If you output the "mod" that comes from your SVM block you will see the SVM model.  This is what it sounds like you're doing.

If you attach your SVM block to an Apply Model block (mod to mod, exa to unl) the apply model will output the same model (mod) and the results of the model applied to the data (exa).  This data might be the plot view your wanting.

The "wei" node of the SVM block outputs weights, presumably the ones you're looking for.


Does that help at all?  If you have a link to the tutorial or video I might be able to give better suggestions.  There're so many operators that generate the various outputs you're looking for it's difficult to say what's missing.

Hi dromiceiomimus,

thanks a lot for your answer.

I meant the following video (at 1:30):

In this video even though only the model is connected with the output, you can see all of the views (especially the plot view) I mentioned in my first post.


Cheers Q-Dog

// Edit
Furthermore, it is described in the RapidMiner Tutorial (open Rapidminer: Help -> RapidMiner Tutorial) step 5 of 26

Oh, I see!  Well, that's quite beyond my ken, I'm afraid.  Hopefully someone with some more experience will chime in.

Q-Dog

That's a pity.

Thanks a lot anyway

Apparently Weight Table, Support Vector Table and Plot View were removed from version 5.1.14 onwards. Not sure why they remove them. It is a shame as the information in Support Vector Table is quite useful.

Hi,

I just check with my up-to-date version of RapidMiner and for me everything seems to be fine!
Are Weight Table, Support Vector Table and Plot View never shown or does this happen just from time to time?

Greetings

Hi,

I also tried this with a fresh SVN version and the views have been missing on my laptop. I tried again in debug mode and, tada, they are back. Could this be a thread problem? This would explain why some people experience this and others do not and maybe even why I got the views in debug mode without changing a line of code. By the way, I already have sent Simon a mail about this containing more details.

Cheers,
Ingo

I have just tried using my RM v5.1.14. The views are back again, without the need to go into debug mode. Very strange indeed. Anyway, glad to hear that they are not removed by design.

You're right, they are back

Don't panic, we are working on it in this very moment

And now it is fixed. At least in the current SVN version. The next update should fix it for you too.

Best,
Nils
