TWINTECH COLLEGE SARAWAK EXPERT SYSTEM BIC 3337 ASSIGNMENT 1 Answer ALL questions in the answer sheets provided. 1. Explain three advantages of AI over Natural Intelligence (NI). AI is permanent whereas natural intelligence is perishable AI offers ease of duplication whereas transferring a body of knowledge from one person to another is a lengthy process AI can be less expensive than natural intelligence 2. AI can be classified into several fields. List two of the fields. Expert System Natural Language Processing Speech (Voice) Understanding Robotics and Sensory Systems Computer Vision Intelligent Computer-Aided Instruction (ICAI) Case-based Reasoning / Neural Networks 3. List down two differences between the conventional systems and the expert systems. Conventional Systems Knowledge and processing are combined in one sequential program Programs do not make mistakes (only programmers do) Do not usually explain why input data are needed or how conclusions were drawn The system operates only when it is completed Execution is done on a step-by-step (algorithmic) basis Needs complete information to operate Expert Systems Knowledge base is clearly separated from the processing (inference) mechanism (knowledge rules are separated from the control) Program may make mistakes Effective manipulation of large databases Representation and use of data Explanation is a part of most expert systems The system can operate with only a few rules (as a first prototype) Execution is done by using heuristics and logic Can operate with incomplete or uncertain information Effective manipulation of large knowledge bases Representation and use of knowledge Page 1 of 2 BIC 3337 EXPERT SYSTEM TWINTECH COLLEGE SARAWAK Efficiency is a major goal Easily deals with quantitative data Effectiveness is a major goal Easily deals with qualitative data (Any two of the above) 4. What are the tools for developing an Expert System? Use a programming languages (usually AI language) Use a shell Use an AI environment (or toolkit) 5. Draw the diagram to differentiate between human expert and expert system problem solving. Page 2 of 2 BIC 3337 EXPERT SYSTEM
