What is Artificial Intelligence?

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are designed to think, learn, and solve problems like humans. These systems can analyze data, recognize patterns, make decisions, and even improve over time through machine learning.

AI is built on various technologies including:

• Machine Learning (ML)

• Natural Language Processing (NLP)

• Computer Vision

• Deep Learning

Types of Artificial Intelligence

AI can be categorized into three main types:

1. Narrow AI (Weak AI)

Designed for a specific task or purpose. Examples:

• Siri or Alexa

• Spam filters

• Netflix recommendation engine

2. General AI (Strong AI)

A theoretical concept where a machine can perform any intellectual task a human can. We haven't achieved this yet.

3. Super AI

An advanced form of AI that surpasses human intelligence in every field. This remains speculative and is the subject of philosophical and ethical debate.

How Does AI Work?

AI systems use algorithms and data to mimic human decision-making. Here’s a simplified process:

1. Data Collection – AI systems need data to learn from.

2. Training – Machine learning models are trained on large datasets.

3. Modeling – The system identifies patterns and relationships.

4. Prediction/Action – Based on input, it provides an output or action.

5. Feedback Loop – AI improves as it receives more data and user feedback.

Example: A spam filter learns from millions of emails to classify new messages as spam or not spam.
