Study Notes
Expert Systems
- Expert systems (ES) are artificial intelligence (AI) programs designed to solve complex problems by emulating human expertise.
- They analyze data and provide recommendations, often used in fields such as medicine, engineering, and finance.
- Key components include:
- Knowledge Base: Contains domain-specific knowledge, facts, and rules.
- Inference Engine: Processes information using logical rules to derive conclusions.
Applications of Expert Systems
- Used in diagnostics for medical conditions, troubleshooting for equipment, and decision support in various industries.
- Examples include MYCIN for diagnosing bacterial infections and DENDRAL for chemical analysis.
Benefits of Expert Systems
- Enhance decision-making by providing quick, consistent outputs.
- Reduce the need for human expertise, allowing tedious tasks to be automated.
Limitations of Expert Systems
- High initial development and maintenance costs.
- May lack flexibility in unpredictable situations and require extensive knowledge to develop.
Artificial Intelligence (AI)
- AI is the simulation of human intelligence in machines designed to think and learn.
- Incorporates various fields such as machine learning, natural language processing, and robotics.
Importance of AI
- AI improves operational efficiency, enhances user experiences, and supports data analysis for better decision-making.
Goals of AI
- Aim to create systems capable of performing tasks that typically require human intelligence, such as visual perception, speech recognition, and decision-making.
Advantages of AI
- Automation leads to increased productivity and efficiency.
- Can analyze massive datasets faster than humans, uncovering insights quickly.
Disadvantages of AI
- Risk of job displacement due to automation.
- Ethical concerns, including bias in algorithms and loss of privacy.
Search Engines
- Search engines are systems designed to search for information on the web using algorithms to return relevant results based on queries.
Voice Recognition
- Voice recognition technology allows computers to understand and process human speech; this facilitates interactions with devices using natural language.
- Commonly used in virtual assistants like Siri, Alexa, and Google Assistant.
Advantages of Voice Recognition
- Enables hands-free operation and accessibility for users with disabilities.
- Provides convenience and efficiency in executing tasks through voice commands.
Disadvantages of Voice Recognition
- May struggle with accents, background noise, or incomplete phrases, leading to misunderstandings.
- Raises concerns over privacy and data security in voice data collection.
Applications of ICT
- Communication Transformation: ICT has revolutionized communication, making it more affordable and efficient
-
Direct Communication: Involves real-time interaction between sender and recipient
- Examples include:
- Real-time messaging apps
- Voice over IP (VoIP) for low-cost voice calls
- Video conferencing for remote meetings
- Examples include:
-
Indirect Communication: Allows for asynchronous message exchange, where the recipient can access messages later
- Examples include:
- World Wide Web (WWW)
- File sharing
- Social networking
- Examples include:
Basic Online Terminologies
- Bandwidth: Refers to the data transfer capacity of a network
- Satellite Downlink and Uplink: Critical for satellite communication systems
Virtual Reality (VR) Applications
-
Military: Used for training in combat scenarios to minimize risks associated with live training
- Includes flight simulation, battlefield rehearsal, medic training, and vehicle operation simulations
