Päättelymoottori

Päättelymoottori is a Finnish term that translates to "inference engine" in English. It is a crucial component in artificial intelligence and expert systems responsible for deriving new information or conclusions from existing data and a set of rules. In essence, it acts as the reasoning mechanism of an AI system.

An inference engine works by applying logical rules to a knowledge base, which contains facts and relationships about a particular domain. When presented with a query or new information, the inference engine searches the knowledge base for relevant facts and rules. It then uses logical deduction techniques, such as forward chaining or backward chaining, to reach a conclusion. Forward chaining starts with known facts and applies rules to derive new facts until a goal is reached. Backward chaining, on the other hand, starts with a goal and works backward to find facts that support it.

The effectiveness of a päättelymoottori depends heavily on the quality and completeness of its knowledge base and the sophistication of its reasoning algorithms. They are widely used in various applications, including medical diagnosis systems, financial forecasting, natural language understanding, and automated decision-making processes. The goal is to mimic human reasoning capabilities to solve complex problems and provide intelligent responses.
