Which one is edible?

Let’s say you want to learn how to classify something, but the ‘rules’ behind the classification are not obvious. For example, given some measurements about a person’s heart, can we tell if they have heart disease? What if you are hiking through the woods and want to know if a mushroom you see is edible or not? Perhaps the stem has a certain color, the head is a certain width, or it has a ‘curtain’ around it. Instead of spending years mastering which mushrooms are edible based on sight, how about you simply get a computer to tell you? Well, with decision trees you can!
