a.What is Intelligence? [2 Marks]It's the ability to acquire and apply knowledge and skills.
b.Describe the four categories under which AI is classified with examples. [2 Marks]Expert systemsExpert (knowledge-based) system: an artificial intelligence system that captures expertise in acertain domain and then applies reasoning capabilities to reach a conclusion. Example: an expertsystem could use facts and symptoms to diagnose a medical problem. The system could thenrecommend a treatment for the condition.Neural networksNeural network : an AI system capable of finding patterns within vast amounts of data. • Usuallygives poor results when first run - then improves through "training" - exposure to: cases withknown solutions, feedback and self-modification.• Widely used for speech and visual pattern recognition
• Neural networks are also used in: - Security training, fraud detection, real estate appraisal,target marketing, Speech and visual pattern recognition - Medicine: Monitoring drug reactions,detecting anomalies in tissues, etc.Genetic algorithmsArtificial intelligence software capable of following trial-and-error processes leading to theevolution of a good result.Genetic algorithms useselection (preference given to better outcomes)crossover (portions of good outcomes are combined in the hope of creating an even betteroutcome)mutation (randomly try new combinations evaluating each combination)Intelligent agentsIntelligent agent - software that assists you , or acts on your behalf , when performing repetitive,computer-related tasks
