Elbow method

[waelodat]

Hi Knimers,

I’m trying to optimize the number of topics (K) to use in LDA. The Elbow method was used to do that, but when I run the Knime workflow the result on the scatter plot shows as the picture attached in this post.

Kindly see the two pics attached to this post:

The first picture represents the Workflow I used.

The second picture represents the scatter plot.

Please tell me why does the result look like this?

Thanks in advance

but when I run the Knime workflow

Which KNIME workflow?

Please tell me why does the result look like this?

You haven’t given us nearly enough information to be able to even begin diagnosing the issue. At the very least you should’ve shared your workflow and some data in your post for us to be able to investigate.

My recommendation is to check the KNIME Hub for other elbow method workflows and compare them to yours.
