Hi,

I am a neophyte using this software. Once you have a model developed with Watson Analytics, how can I see how the model would classify backwards each case in my dataset?  Can I save the model and apply it to a different test set to classify unknowns?

Thank you, Alberto

Hi Alberto,

I am not sure I fully understand what is being asked but it seems like you are interested in creating a 'template' that you can use for multiple data sets, i.e. swap in a new data set and apply the template, is that correct?   Standard 'Discoveries' in WA are tied to a single data set. The data set can't be swapped out for another one. 

You  would need to use 'Expert Storybooks'. These can either be built by combining several discoveries into a single 'Storybook' yourself, or downloaded from the Analytics Exchange where you will find pre-built storybooks created by other users to accomplish common business tasks.   You could then apply your own data to these templates. Expert storybooks are the only way to build a template and apply different data sets.

Here is some documentation (you will need to be signed in to WA to access):
https://watson.analytics.ibmcloud.com/wa_docs/help/#/SS4QC9/com.ibm.solutions.wa_an_overview.2.0.0.doc/wa_storybook_intro.html

As for the question regarding how to see how a model would classify backwards against the data, I am not too clear on what is being asked. You may just want to apply opposite sort order on the visualization. If it is a predictive visualization (Decision rules of a decision tree, for example), you may want to flip the visualization by tapping the opposite arrow in the top left hand corner to show the inverse correlation.

I hope this helps. I would definitely encourage you to open a support case where someone from the support team will be able to assist with more specific issues.
