perceptron VS minimal-spanning-trees

The example above perfectly demonstrated how a lacking understanding of math can be harmful, but what's the case with frameworks? They have a similar issue. When I started doing coding and research on it outside of school, one of my first goals became to write some code that included the use of AI, so I went to learn AI. I started off with a freeCodeCamp seven hours course, hoping I could make AI when I'm done following that tutorial. I was completely wrong. I just followed the steps, did whatever they did and made some very simple AI. When I then tried using that knowledge on my own case, I quickly realised that I have no idea how to do that. And not to mention, every time I had a problem the guy from the tutorial didn't have I would search for hours to solve it. Simply put: I wrote words, neither understanding the sentences they made nor the letters that were used. The truth was: I was lacking an understanding of the math behind Artificial Intelligence and wanted to directly start coding. To fix this I started off watching tutorials on the math, learned basic calculus and wrote a copy of the Perceptron in JavaScript. The first article I wrote was about that.

If you just want the code, you can get it here

The first time I recognised this problem is when I had to draw a line between two points that could be placed completely randomly. The project (you can look at here, instructions and location are in the readme) was for a course mixing math and IT. My teacher gave me the task to "write a program that makes it able for me to draw dots, connect them with lines of a weight I choose and then the code searches for the minimal spanning tree. If I click the lines I should be able to change their weight". Now what is step one, when implementing that? Making it able for the user to draw dots and connect the lines. And how do you calculate the line between those two dots? Give it a thought before you read the next part. Trigonometry and Pythagorean's Theorem could be a very useful tool. If you had that thought, it was (obviously) because you know the math to approach problems like these exist. If the problem was a different one maybe you don't know the math and because it is such a specific task you also won't find any good sources to it. How did I solve that problem? Every time a user creates a line between two dots, my code plots a triangle, where the created line is the hypothenuse and draws it. Here is the code, if you are interested.
