Algorithms
- Generate pre-defined outputs on basis of previously programmed rules which are hard-coded in the system.
- Rule-based Algorithms have fixed result and the result doesn't change or evolve based on the data.
- Typically in the form of if-then expressions.
Rule-based system
- Set of facts: Domain-specific knowledge - Database
- Set of rules: Rules engine which makes up the knowledge base
- Inference engine; Capable of deriving conclusions.
