How to compare and check the differences of your NLU Model on two different instancesSummaryIn this How To, we will be going over how to check if your NLU Model on one instance is the same or has differences on another instance.InstructionsDownloading the trained model file: Get the sys_id of the NLU Model you are wanting to check.NLU Model sys_id can be found in the [sys_nlu_model] table. Or by going to the NLU Model and getting the sys_id from the URL.Head over to the [ml_model_artifact] table. Filter 'Model ID' = "authoring.model.artifact", and add a CONTAINS on 'Solution' = "*SYS_ID". (SYS_ID being the NLU Model sys_id). Add the 'Created' field to the columns and sort so the newest records are at the top of the list.Click the newest record for that model.At the top left should be an attachment ([sys_attachment] table). Go ahead and click that attachment to download it.Do this for the other instance as well. By following that process on both instances, we now have the trained models. Next, find a "Difference Checker" online or an application you can get. By placing the contents (JSON) into a difference checker, we can start seeing what kind of differences there are between the models. Any differences in the NLU models could result in different predictions and behaviors in Virtual Agent.Related LinksThe authoring model artifact files are the JSON version of your NLU Model. By checking these two files, you can see direct differences between models on two different instances.
