To understand this, let’s start with what is machine learning and how does the bots learn. This will clear how does these words came into picture of machine learning and what does they mean.

Let’s consider an example where you are shown two pictures one is of a dog and another is number 5 and you are asked what is what? Being an human you just know that yes, this is a dog and that is number 5 but how will the machine or the bots know?

We have to create a complex algorithm that will tell them to crawl the image pixel by pixel and find patterns in that picture that matches pixel patterns usually found in known dog images and give an estimated guess. Human brains have a complex wiring of neurons that learns every second. Similarly we will have to create complex bots with evolving pattern recognition intelligence which they develop over time as they keep learning.

How they learn?

Human programmers create a teacher bot and a builder bot who have simpler brains. Builder bot builds student bots and keeps and discards them based on their test grades.
