The text emphasizes that the power of an expert system lies in separating the knowledge base from the inference engine. This allows the system to be updated by adding new rules without rewriting the engine code. Kim and her team worked through the night

The book walks through a simplified diagnostic system for bacterial infections. It demonstrates how certainty factors (a number between -1 and 1) handle medical uncertainty—a topic rarely covered in modern machine learning courses. This allows the system to be updated by
