Well, I'm wondering if you might have other data queued up in the read buffer from previous tests, or something like that.

In that case, see what the experience is like with Google Dialogflow first. Then try out another alternative called Rasa (<https://rasa.com/>) which is open source and more flexible. If you really want to get familiar with the underlying ML concepts driving these chatbots from scratch, I suggest auditing one of the many free online courses on either Udacity, Coursera or YouTube. The main concepts around ML I think you should focus on are “supervised learning”, “recurrent neural networks”, “word embeddings”, and “reinforcement learning”. If you have a decent grasp of probability, statistics and differential calculus then you should be able to get stuck into it right away. I also suggest taking a cursory look at “speech act theory” to give you an idea of how people generally structure chatbot conversations.

Since you're already iterating, can't you just add a condition to `continue` if you found a criteria for exclusion?
