Thisnwas great, very well explained and from a point of view I didn't read before.

Just a thought before I forget to mention, that could be interesting to discuss in the future. I would like if at some point there is a discussion on how the theory of ML might fit with Complexity theory. For instance, most of us believe P!=NP. However, if Metric TSP has a polynomial approximation then P=NP.

So a question I ask myself usually is what happen if we find a ML algorithm that approximates TSP amazingly well, it cannot be categorized as a polynomial algorithm unless is a Decider of the problem, which means 100% accuracy.

So I always have the question, is it possible to reach this 100% in a problem like this (probably not) and if not, then Why? What would be a mathematical proof for that, again from theorethical point of view, assuming we have all the data that we might need, all the features that we need, etc.

## Foundations of ML #1 - What is Machine Learning?

Very easy to understand, and not the most simple subject. Nicely done, Daniel and Ale!

Thank you for such a great article

Truly masterful. It provides a truly intuitive approach to understanding the basics of ML.
