Where is the "Write Weights" ans "Read Weights" operators?

yasinkaya

How do I write to the file the features (weights output) I get in the feature selection operator.

Older versions of the RM had "write weights" and "read weights" operators for this purpose. But now, in the newest version they are depreciated.

Hi @yasinkaya

The Data to Weights operator unfortunately support a different usecase (creating Weights for the attributes of the provided ExampleSet).
What you are looking for is the ExampleSet to Weights operator from the converters extension (install it over the marketplace).

Hopes this helps,
Best regards,

Hi,

For bi-directional (aka save -> read again) workflows of our internal data representations, we want users to use the repository. That way, we can be more confident the files are not broken by accident due to external editing (which is not a good idea), and we also avoid cluttering data all over the disk which would be easier to lose. Furthermore, we also don't want a separate operator for every data/model/etc object we have, so we unified it via Store and Retrieve a long time ago.
The last remnants of the past like Write and Read Weights have therefore been eliminated and will not come back.

Regards,
Marco

Hi,

we recommend to use Weights to Data first and then use the normal Write-CSV or Write-Excel if you need it readable. Otherwise you can use Store to write it into the repository.

Best,

Martin

Thank you Mr. @mschmitz.

Then how do I do the opposite of that?

I can't get true features saved to CSV file when I try to filter data using "read csv" and "data to weights". (Edit: Corrected this sentence, I didn't get an error message)

How to perform the function "read weights".

Hello @yasinkaya

Looks like your process flow is fine. Can you inform the error details?

yasinkaya

There is no error. Sorry. But it don't give expected output from the weights port. I'll add a picture. 

yasinkaya

It is not select features using saved features to CSV file. 
Why Write Weights and Read Weights deprecated?

If there is no operator with the same convenience instead, why did these operators removed?

yasinkaya

Thanks you very much @Marco_Boeck and @tftemme.
This two solutions enough for me.
