Define AI, importance and applications

Short answer

AI is the study of intelligent agents that perceive environments and act to achieve goals. Importance: automates repetitive work, improves accuracy/speed, supports decisions with big data, provides 24/7 availability, solves hard search problems, enables personalization, assists people. Applications: healthcare (diagnosis, drug discovery), education (tutors, grading), finance (fraud detection), agriculture (crop monitoring), transport (self-driving), NLP (translation, assistants), computer vision (face recognition), robotics, games, security, e-commerce recommendations.

Define Artificial Intelligence (AI). Describe the importance and practical applications of AI.

Artificial Intelligence (AI) is the study and design of intelligent agents, that is, systems that perceive their environment and take actions that maximise their chance of achieving their goals. Russell and Norvig group the definitions into four views: systems that think like humans, act like humans, think rationally and act rationally.

Importance of AI

  1. Automation of repetitive work: AI performs routine and dangerous tasks faster and without fatigue (factory robots, data entry).
  2. Accuracy and speed: Machines process huge data and make fewer errors in tasks such as diagnosis, fraud detection and translation.
  3. Decision support: AI finds patterns in big data that humans cannot see and recommends better decisions.
  4. 24 x 7 availability: Chatbots and monitoring systems work without breaks.
  5. Solving hard problems: Planning, scheduling, route finding and game playing are search problems too large for manual solution.
  6. Personalisation: Recommendations, adaptive learning and smart assistants adjust to each user.
  7. Helping people: Assistive technology for the disabled, early warning for disasters and better access to health and education.
