Study Notes
Artificial Intelligence Overview
- AI encompasses techniques designed to efficiently organize and utilize vast amounts of both unstructured and constantly changing data.
- Key characteristics of effective AI knowledge representation include perceivability, modifiability, and utility in various situations, even when incomplete or inaccurate.
Applications of AI
- Gaming: AI enhances gameplay in strategic games like chess and poker by analyzing numerous potential positions using heuristic knowledge.
- Natural Language Processing (NLP): Enables computer interactions using human language, enhancing user experience.
- Expert Systems: These integrate technology and domain-specific knowledge to provide reasoning, advice, and explanations to users.
- Vision Systems: Capable of interpreting visual data for applications like aerial photos for mapping, medical diagnostics, and facial recognition for law enforcement.
- Speech Recognition: Allows systems to understand spoken language, adapting to various accents and background noise.
- Handwriting Recognition: Enables systems to read written text from paper or screens.
AI Search Techniques
- Greedy Best First Search: Expands nodes that appear closest to the goal; quicker but prone to getting stuck in loops and is not optimal.
- Local Search Algorithms: Start from an existing solution and explore neighboring solutions. May yield a valid solution even if interrupted.
- Hill-Climbing Search: Iterative method that incrementally adjusts a solution to find improvements until no further enhancements are found; lacks completeness and optimality.
- Local Beam Search: Maintains multiple states, selecting the best k based on their successors until a solution is reached.
- Simulated Annealing: Mimics the physical process of cooling metals; involves variable temperature to escape local optima.
Fuzzy Logic System Example
- An air conditioning system uses five-level fuzzy logic to adjust temperature by comparing current and target values through a series of steps including defining variables, constructing membership functions, and evaluating rules.
Expert System Technology
- Development environment includes hardware and software, such as workstations and high-level programming languages like LISP and PROLOG.
- Tools assist in the creation process by providing rapid prototyping, debugging, and knowledge representation capabilities.
- An expert system shell offers the base framework without a knowledge base, supporting knowledge acquisition and inference.
Steps in Expert System Development
- Identifying the Problem Domain: Ensure the suitability and cost-effectiveness for an expert system.
- System Design: Select appropriate technology and integration with existing systems.
- Prototype Development: Acquire domain knowledge and represent it with rules.
Differences Between AI Programs and Robots
- AI programs function in simulated environments with symbolic inputs, while robots interact with real physical environments using analog signals.
- Robots require specialized hardware with sensors, unlike general-purpose computers used for AI programs.
Robot Locomotion
- Types of Locomotion: Includes legged, wheeled, tracked, and combinations thereof.
- Legged Locomotion: Consumes more power and requires complex leg coordination for movement; higher count of legs leads to exponentially more possible movement events.
- Wheeled Locomotion: More efficient in power consumption and easier to implement due to fewer stability concerns compared to legged locomotion.
