You are advised to implement an 80/20 split with training and test utterances. This means that 80% of new utterances harvested from the conversation logs should be used as intent training utterances and 20% for testing.
Why is this a good practice?

• A. Batch testing works more efficiently when there is a ratio of one test utterance for every five training utterances.
• B. Adding 100% of user phrases to the intent would overload the model.
• C. By keeping 20% for testing, you are able to test the model with data on which it has not been specifically trained.
• D. By performing an 80/20 split, you are randomizing which data is added to the utterances.
