NLU results for same sentence or phrase Vary when typed in Uppercase vs lowercaseDescriptionNLU results for same sentence or phrase Vary when typed in Uppercase vs lowercaseSteps to Reproduce Typing the same sentence in lower cases and upper cases vary when it come to matching with Topics.Attaching Screenshots examples.When you type "details about my case" it goes to "Check case status" and show list of topics but "DETAILS ABOUT MY CASE" matches with 3 topics.Another example : Typing hi or hellow matches with greeting topic but not "HI" or "HELLO" WorkaroundNLU is case sensitive, we have built in tolerance in the neural model to mitigate this issue but there are some words where the neural network is biased e.g "HI"(Hawaii ) is seen so many times in its corpus that is is biased towards it being a noun. These are the place where our build in tolerance fails and we expect users to add these samples to the Model. We cannot lowercase everything automatically as it can have negative effects. This is expected behavior and by design in all currently supported releases.Related Problem: PRB1350551
