People often use the term “artificial intelligence” without really understanding what it’s supposed to mean. We can’t blame them. AI can mean what you want it to. It’s an abstract term, to a good extent. And if you talk to experts in the science of machine learning, you might even learn that they don’t really recognize artificial intelligence as a technology but more as a marketing buzzword used to sell machine learning. So, for the sake of simplicity, understand that machine learning is one of the most effective and mature approaches to realizing algorithms that make programs and machines seem “intelligent.”

Well, we’re going to go a lot deeper than that to help you understand how machine learning is the key force shaping the world of artificial intelligence.

Machine learning is about data — mostly

Machine learning is mostly based on using lots and lots of training data and good algorithms. Though there’s a lot of excitement in technology circles about sophisticated algorithms, particularly deep learning, it must be understood that most applications of machine learning are a result of good data. Machine learning could exist without good algorithms, but it can’t exist without good data.

This is a major fact for everyone involved in the artificial intelligence industry. The path to the future is paved on the foundation of good data more than anything else. That’s why you’d observe that the most remarkable examples of artificial intelligence are in industries where data scientists have access to massive data.

“Garbage in, garbage out” — this is the rule of thumb in software development, as old as the idea of software itself. It applies particularly well to machine learning, and it’s very important that developers and data scientists understand it. This is a key limitation of machine learning. It can only identify patterns that exist in the training data, and that’s the sole basis for its learning.

If a machine learning model generates good results based on its training data, expect it to generate results of a similar quality in a production environment. However, that’s only when the production data follows the same distribution as that of the training data. Skews between training and production data are guaranteed to result in the errant behavior of your model.
