Artificial Intelligence (AI) has seen a massive boom in recent years but there are very few people who actually know what they are, how they work, and why we need them. Even though machines using AI have been an integral part of all our lives for many years, there is still a huge gap between using those machines and understanding them. Therefore, using one of the most commonly used AI algorithms, I try to bridge the gap and explain the mechanism behind AI and machine learning while exploring the question “How do machines learn?”.
