What is predicate logic in AI? Understand it in simple terms

If you're just entering the world of artificial intelligence, what is predicate logic in AI is likely a question on your mind. In fact, Predicate Logic, also known as First Order Logic, is a powerful language for representing and reasoning about knowledge in AI.

Predicate Logic goes a step further than Propositional Logic. In it, we can express objects, their properties, and relationships between them, rather than just true or false. For example, "Rahul is a doctor" is written as "Doctor(Rahul)" in Predicate Logic. Similarly, "Every human is mortal" is represented as "∀x(Human(x) → Mortal(x))".

Predicate Logic is widely used in AI in Expert Systems, Natural Language Processing, Machine Learning Models, etc., because it allows complex information to be stored, processed, and inferred in a formal manner. This allows computers to easily draw conclusions based on data, such as "If a bird exists and has wings, then it can fly."

Tip: How to get started with predicate logic?

If you want to advance in AI, thoroughly understand the basic symbology of predicate logic (such as ∀, ∃, →, ∧, ∨) and practice using it in simple everyday examples. This is crucial for building a strong logical foundation in AI.
