• B.True Positives / (True Positives + False Positives)
• C.True Positives / (True Positives + False Negatives)
• D.False Positives / (True Negatives + False Negatives)

What is important when creating an IBM Watson Visual Recognition classifier?

• A.Provide an approximately equal number of both positive and negative examples of pictures to train with
• B.Make sure training images are very high resolution
• C.Collect training images for the same classification that are very similar to each other
• D.Ensure use of only PNG formatted images

Before a developer can work with any of the IBM Cloud services, they need to obtain service credentials.
What is the proper procedure to do this in IBM Cloud?

• A.The IBM Cloud credentials are the same as your service credentials.
• B.Log-in to IBM Cloud, navigate to your account, and view your user credentials.
• C.Log-in to IBM Cloud, navigate to your account profile, then copy the account credentials into the application for service access.
• D.Create a service instance within IBM Cloud, create the service credentials, use the service credentials in the application.

When running an application on IBM Cloud that uses the IBM Watson assistant service, what is the prerequisite to use the service?

• A.That the Watson Assistant service credentials username and password are provisioned and referenced for the application.
• B.That the Watson Assistant service uses robust conversation collected from actual user questions.
• C.That the Watson Assistant service is associated with an IBM Watson speech to Text service.
• D.That the Watson Assistant service is bound to the application.

How can the threshold for the confidence level be set for the intent of a dialog node in the IBM Watson Assistant service?

• A.It can be a condition within the Dialog node alongside the intent. For Example, intents
  [0].confidence<0.8
• B.On the drop-down of the Dialog node, the condition for confidence levels can be set for the intents defined in your Dialog node.
• C.The confidence level cannot be set within the Dialog and should be done programmatically within the application code.
• D.The confidence level threshold is already set for each Dialog node at "0.2". It can be overridden by turning off the confidence level on the improve tab within the Watson Assistant workspace.
