> If one understands principles In that case, the hard part is already done. Understanding the principles is what takes the most work, not writing or adapting the code. In fact, understanding the principles is IMO a prerequisite for being able to successfully adapt the code. Now, using something like TensorFlow in another later article is of course super useful. It also will clarify why TensorFlow is more confusing and why this article was written. I find the article enlightening, and specific libraries like TensorFlow are just "implementation details".
