Training the model for the IVA channel
         To enable Pega Intelligent Virtual Assistant (IVA) in your application to react
            to user requests, teach the system to recognize different types of input in a chat
            conversation. When you train the text analytics model for the IVA, the system learns
            from training records, improves the artificial intelligence algorithms, and learns to
            react in the correct way.
 For example, after you train the text analytics
        model for an IVA and a user asks about a car insurance quote in the chatbot, the system
        detects the correct topic and entities. As a result, the IVA starts a car insurance business
        case and asks the user several follow-up questions. 
        Before you begin: Build an IVA by configuring an Alexa, Unified Messaging, or Web
            Chatbot channel. For more information, see Building a conversational channel.
        To ensure that the IVA learns from the training records and detects the correct topics and entities, apply the training changes to the text analytics model for the system. You apply changes to the model after you enable the training data recording, and then create and review the training records.
