Introduction to Artificial Intelligence
Artificial intelligence is the field of building computer systems that can perform tasks we normally associate with human intelligence—like understanding language, spotting patterns, and making decisions.
What is AI?
AI systems use data, algorithms, and computing power to produce useful outputs. A spam filter classifies messages, a navigation app predicts traffic, and a voice assistant interprets speech. Each turns inputs into an output using learned or programmed rules.
AI is a broad umbrella. Machine learning is one way to build AI: instead of writing every rule by hand, we train a model to learn patterns from examples.
The simple model
Input + process → output
Data enters a system, the model finds a useful pattern, and the system returns a prediction or action.AI, machine learning, and deep learning
| Term | Meaning | Example |
|---|---|---|
| AI | Broad goal of machine intelligence. | Route planner |
| Machine learning | Learning patterns from data. | Fraud detection |
| Deep learning | Layered neural-network learning. | Image recognition |
Example
function recommendNextStep(topic) {
if (topic === 'AI') return 'Learn machine learning basics';
return 'Start with Introduction to AI';
