Those methods can use a variety of techniques to learn rules, which is called training the model. Machine learning (ML) is an umbrella term for a number of statistical inference methods for generating rules (aka models) from large amounts of data (aka observations). For both types of reasoning, the confidence we have in the learned rules depends on the confidence we have in the observations. Inductive reasoning usually involves statistics to generate rules that are likely to be true. Some examples include expert systems and automated theorem proving.

Deductive reasoning can take a series of inputs and deduce a new rule using logic – often these new rules are more generalizable or more succinct ways of representing seemingly complex behavior. If we go one step more abstract, we get to AI which can learn rules based on observations. In our tic-tac-toe example, the AI would now be able to consider chains of moves and the potential outcomes of certain sequences of decisions. Simulations can also exhibit emergence, the property of a system as a whole to develop properties on large scales that aren’t seen on small scales.
Simulations also utilize rules, but rather than just matching the inputs, a simulation is able to extrapolate into potential future states and can incorporate randomness into its decisions to account for input instability. As the behavior gets more complicated, the ruleset must also, and it becomes more and more difficult to build the logic to resolve conflicts. Systems like this don’t scale well with complexity, though. The inputs would be the locations of the plays made so far and the turn number, and the output would be the location to play next. It’s easy to imagine building a ruleset for tic-tac-toe.
Rule-based systems are essentially a collection of rules and an engine that is capable of performing actions (and resolving conflicts between multiple actions) based on the input it sees. There are a number of ways to accomplish them: There is also the concept of general artificial intelligence able to apply problem solving in a variety of ways rather just in one predefined manner. This is also considered to not yet be feasible, with even the most sophisticated personal assistant algorithms just boiling queries down into narrow tasks under the hood.
These specific tasks are examples of weak, or narrow, AI. Of course, we could imagine a stronger kind of AI capable of not just performing specific tasks but of actually having a form of consciousness or mind – but this remains in the realms of philosophy and science fiction. You may have heard about algorithms capable of beating highly skilled humans at complex games like Chess or Go. Tasks like these have historically been difficult for computers, but search for image misclassification rates now and you’ll see reports of algorithms having better success than humans. That’s why we see artificial intelligence being applied in order to do things like handwriting or voice recognition, identification of images, evaluating the meaning of sentences, or music composition. One way of thinking about practical AI is as an umbrella term for efforts to give computers the ability to perform intelligent tasks as well as humans can or exhibit behaviors that are associated with humanity. In this article I’ll go over the big picture definition of AI and how it differs from machine learning and deep learning. These days, AI is often used as a synonym for deep learning, perhaps because both ideas entered popular tech-consciousness at the same time. When you think of artificial intelligence (AI), do you envision C-3PO or matrix multiplication? HAL 9000 or pruning decision trees? This is an example of ambiguous language, and for a field which has gained so much traction in recent years, it’s particularly important that we think about and define what we mean by artificial intelligence – especially when communicating between managers, salespeople, and the technical side of things.
