Every time we make changes to the knowledge base, it is wise to click Save and Train. This will ensure that our model is up to date, with the most current question-and-answer pairs.

Once we have trained the model, we can test it. This can be done by clicking the Test button on the right-hand side. This will present us with the following chat window:

From this chat dialog, we can test some or all of our questions to verify that we get the correct answers. We can also improve the model by asking questions in different ways. In some cases, this will present us with the wrong answer.

If we have been presented with the wrong answer, we can change this by selecting the correct one. With any given question, the possible answers will be listed by clicking the Inspect button beneath the question, ordered by probability. Selecting the correct answer and retraining the model will ensure a correct answer when asking the same question later.
