3) What are some of the problems that make machine vision so challenging?
- masses of irrelevant data

4) What is the knowledge base? What is an expert system? How are the two related?
Knowledge base: contains a system of rules for determing and changing the relationship among facts
Expert system: a software program designed to replicate the decision making process of a human expert
Knowledge bases lie at the heart of every expert system used in business, science, and industry.
