Oracle DVD Cluster Model Quality Tab contains 'No Data'

Summary

Oracle DVD Cluster Model Quality tab contains 'No Data'

Content

When I train a clustering model in Oracle Data Visualization desktop(latest version) and then inspect the model I see 'No Data' in the quality pane.  I would expect to see ellipses indicating the PCA which would show me the quality of the Model.  The model does create clusters and produces data with the cluster ID.

Does anybody have any thoughts

As you are talking about PCA, I believe this is the custom model that you have build

The custom model building is split in to six parts as per the blog http://oracledataviz.blogspot.com/2018/03/custom-model-scripts-for-oracle.html

You need to look at the step 5 and step 6 on how to add the related data sets and populate the quality tab. The links in these steps though talk about regression and classification, you can take a look at how the clustering algorithm is built and how the quality tab is being populated. In my system, I can access the .py files from C:\Program Files\Oracle Data Visualization Desktop\OracleBI1\bifoundation\advanced_analytics\python_scripts\obipy\obiml this location

Oracle DV is not working in my laptop, will take a look and will post you more on this

 

Hope this helps
