1. Case-based reasoning. ESs that use this approach draw inferences by comparing a current problem to hundreds or thousands of similar problems of past cases. It is best used when there are too many variations to generalize into rules.
2. Neural networks. Neural networks are a type of decision-making system. They contain links and nodes that fire signals to other nodes.
3. Rules-based systems. This is the most common form of knowledge representation. The rules are obtained from experts who draw upon their own expertise, experience, and common sense ways of doing business, regulations and laws to state the rules. They generally exist in the form of If-Then statements.
