AI, or Artificial Intelligence, is a branch of computer science that focuses on creating machines or software that can perform tasks that normally require human intelligence. This includes things like learning, reasoning, problem-solving, understanding language, recognizing patterns, and even making decisions.
1. Types of AI
a. Narrow AI (Weak AI):
- Designed for a specific task.
- Examples: ChatGPT, Siri, recommendation systems on Netflix or Amazon, self-driving car software.
b. General AI (Strong AI):
- Would have human-level intelligence across a wide range of tasks.
- Example: AI that can reason, learn, and plan like a human. (We don’t have this yet.)
c. Superintelligent AI:
- Hypothetical AI that surpasses human intelligence in all areas.
- Mostly in theory/future speculation.
2. How AI Works
AI often relies on these core techniques:
- Machine Learning (ML): Systems learn patterns from data rather than being explicitly programmed.
- Deep Learning: A type of ML using neural networks inspired by the human brain. Useful for image recognition, speech, and natural language processing.
- Natural Language Processing (NLP): Lets machines understand and generate human language (like me!).
- Computer Vision: Allows machines to see and interpret images or video.
- Reinforcement Learning: AI learns by trial and error to maximize rewards, often used in robotics and games.
